Description

Technical Field

[0001] This utility model relates to the technical field of circuit board processing equipment, specifically to a chip mounting device for circuit board production and packaging. Background Technology

[0002] The surface mount equipment in circuit board manufacturing is a core component of the surface mount technology production line. It is mainly used to mount electronic components, such as resistors, capacitors, and chips, onto the surface of printed circuit boards (PCBs) with high precision and efficiency, thereby improving the processing efficiency of circuit boards.

[0003] For example, the utility model patent disclosed in CN217011327U discloses a chip mounter for circuit board production, which includes a pickup, a base plate, and a turning mechanism. A turntable is rotatably provided at one end of the top of the base plate. A square groove is provided on the top of the turntable. A partition is placed in the square groove along the length direction. The partition slides with the square groove and can slide along the width direction of the square groove. A moving mechanism is movably provided on the top of the base plate. The pickup is set on the moving mechanism and can move arbitrarily above the base plate through the moving mechanism. The turning mechanism includes a slide rod, which is horizontally set at one end of the base plate. The slide rod passes through the end face of the base plate and slides with the base plate. The end of the slide rod is connected to the turntable drive. Sliding the slide rod can drive the turntable to rotate by an integer multiple of 90 degrees. The user only needs to slide the slide rod to control the turntable to rotate by an integer multiple of 90 degrees through the transmission mechanism. With the help of the partition in the square groove, the electronic components are limited and the electronic components are neatly turned so that they can be directly picked up and used, avoiding the problems of inconvenience and large errors of manually rotating electronic components.

[0004] Although the aforementioned equipment can perform rotating placement operations on circuit boards, it is not convenient to adjust the placement positioning operation of the circuit board at any angle. At the same time, when performing placement operations on batch circuit boards, its feeding efficiency is also insufficient. Therefore, there is an urgent need for a placement equipment for circuit board production and packaging to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a chip mounting device for circuit board production and packaging, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chip mounting device for circuit board production and packaging, comprising a support base for support, a support top plate fixedly disposed at the center of the upper end face of the support base, a servo motor disposed at the rear end face of the support base, a guide screw disposed at the output end of the servo motor, and a fixed guide shaft disposed on the inner end face of the support base away from the guide screw.

[0007] The alignment device is threadedly slidably connected to the inner end face of the support base via the guide screw, and a circuit board is fixedly snapped onto the inner end face of the alignment device.

[0008] The patch module is provided in three sets, and the three sets of patch modules are fixedly arranged at equal intervals on the inner end face of the support top plate.

[0009] Preferably, the alignment device includes a support bracket, the inner end face of which is rotatably engaged with two sets of transmission screws, and a synchronous pulley is fixedly arranged on the side end face of the transmission screws. The two sets of synchronous pulleys are meshed and connected by a synchronous belt. Threaded guide seats are symmetrically arranged near the upper part of the side end face of the support bracket. Three sets of driving bevel gears are equidistantly arranged on the outer end faces of the two sets of transmission screws. Three sets of limiting devices are equidistantly arranged on the inner end face of the support bracket. A stepper motor is arranged on the rear end face of the support bracket opposite to the transmission screws.

[0010] Preferably, the limiting device includes a guide turntable, a driven bevel gear is fixedly provided at the center of the lower end face of the guide turntable, a three-axis cylinder is symmetrically provided on the inner end face of the guide turntable, and a locking clamp is provided at the output end of the three-axis cylinder.

[0011] Preferably, the guide turntable is rotatably engaged with the inner end face of the support bracket, and the active bevel gear meshes with the driven bevel gear. The three sets of active bevel gears can quickly and accurately adjust the angle of the three sets of guide turntables and the circuit board to the bottom of the mounting module by meshing with the driven bevel gears, thereby improving the adaptability of the equipment for subsequent mounting of the circuit board.

[0012] Preferably, the two sets of locking clamps are fixedly engaged with the circuit board, which can effectively improve the stability of subsequent locking and limiting of the circuit board.

[0013] Preferably, the support bracket is threadedly slidably connected to the upper end face of the support base by means of the threaded guide seat and the guide screw. When the circuit board is cyclically fed, the servo motor can be threadedly connected to the threaded guide seat through the guide screw, thereby alternately driving the two rows of limiting devices to position at the bottom of the chip module, improving the efficiency of processing the circuit board.

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

[0015] 1. This utility model, by setting up an alignment device, enables the stepper motor to synchronously drive two sets of transmission screws to rotate when adjusting the placement of circuit boards at any angle. This is achieved through the synchronous belt and synchronous pulley. The two sets of transmission screws can then mesh with the active and driven bevel gears, thereby synchronously driving the three sets of guide turntables at the workstation to rotate. This allows the circuit board to be aligned to the bottom of the placement module at any angle for placement, effectively improving the efficiency of the equipment in placing circuit boards. At the same time, the circuit boards inside the two rows of guide turntables can be alternately guided to the bottom of the placement module, effectively improving the efficiency of the equipment in feeding circuit boards and also improving the efficiency of placing circuit boards.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides an embodiment of a chip mounting device for circuit board production and packaging, comprising a support base 1 for support, a support top plate 4 fixedly disposed at the center of the upper end face of the support base 1, a servo motor 7 disposed at the rear end face of the support base 1, a guide screw 3 disposed at the output end of the servo motor 7, and a fixed guide shaft 6 disposed at the inner end face of the support base 1 away from the guide screw 3.

[0024] Alignment device 2 is threadedly slidably connected to the inner end face of support base 1 via guide screw 3, and circuit board 8 is fixedly snapped onto the inner end face of alignment device 2.

[0025] The surface mount module 5 consists of three sets, which are equidistantly fixed on the inner end face of the supporting top plate 4.

[0026] The alignment device 2 includes a support bracket 23. Two sets of transmission screws 24 are rotatably engaged on the inner end face of the support bracket 23. Synchronous pulleys 28 are fixedly installed on the side end face of the transmission screws 24. The two sets of synchronous pulleys 28 are meshed and connected by a synchronous belt 27. Threaded guide seats 21 are symmetrically arranged near the upper part of the side end face of the support bracket 23. Three sets of driving bevel gears 26 are equidistantly arranged on the outer end face of the two sets of transmission screws 24. Three sets of limiting devices 22 are equidistantly arranged on the inner end face of the support bracket 23. A stepper motor 25 is arranged on the rear end face of the support bracket 23 opposite to the transmission screws 24.

[0027] The limiting device 22 includes a guide turntable 223. A driven bevel gear 224 is fixedly installed at the center of the lower end face of the guide turntable 223. A three-axis cylinder 222 is symmetrically installed on the inner end face of the guide turntable 223. A locking clamp 221 is installed at the output end of the three-axis cylinder 222.

[0028] The guide turntable 223 is rotatably engaged with the inner end face of the support bracket 23, and the active bevel gear 26 meshes with the driven bevel gear 224. The three sets of active bevel gears 26 can quickly and accurately adjust the angle of the three sets of guide turntables 223 and the circuit board 8 to the bottom of the mounting module 5 by meshing with the driven bevel gear 224, thereby improving the adaptability of the equipment for subsequent mounting of the circuit board 8.

[0029] Two sets of locking clamps 221 are fixedly engaged with the circuit board 8, which can effectively improve the stability of subsequent locking and limiting of the circuit board 8.

[0030] The support bracket 23 is threadedly slidably connected to the upper end face of the support base 1 by the threaded guide seat 21 and the guide screw 3. When the circuit board 8 is cyclically fed, the servo motor 7 can be threadedly connected to the threaded guide seat 21 through the guide screw 3, thereby alternately driving the two rows of limit devices 22 to position to the bottom of the patch module 5, thereby improving the efficiency of processing the circuit board 8.

[0031] Working principle: Before performing surface mount processing on batches of circuit boards 8, the operator can position the feeding module of the circuit board 8 on both sides of the upper part of the support top plate 4 to facilitate feeding into the two rows of guide turntables 223. During feeding, the external feeding module can position the circuit board 8 on the upper part of the locking clamp 221. At this time, the locking clamp 221 is in a disengaged state. Subsequently, two sets of three-axis cylinders 222 are activated. The two sets of three-axis cylinders 222 can perform omnidirectional limiting operations on the outside of the circuit board 8 through the locking clamp 221. When performing surface mount processing on the circuit board 8, the operator can start the servo motor 7. At this time, the servo motor 7 can drive the guide turntables 223. Rotating the lead screw 3 allows it to connect with the threaded guide seat 21, thereby positioning the support bracket 23 and the row of locking clamps 221 on its upper part to the bottom of the surface mount module 5. Simultaneously, if it is necessary to adjust the surface mount angle of the circuit board 8, the stepper motor 25 is started. The stepper motor 25 can synchronously drive the two sets of transmission lead screws 24 to rotate through the synchronous belt 27 and the synchronous pulley 28. This allows the two sets of transmission lead screws 24 to mesh with the driven bevel gear 224 through the active bevel gear 26, thereby adjusting the circuit board 8 at any angle. Subsequently, the surface mount module 5 can complete the surface mount processing of the circuit board 8.
