Description

Technical Field

[0001] This utility model relates to the field of PCB board production technology, specifically a PCB board stacking device. Background Technology

[0002] PCB boards are a fundamental material in the electronics manufacturing industry. During mass production, cut PCB boards need to be stacked in an orderly manner to facilitate subsequent processing, storage, and transportation. With the rapid development of the electronics industry, the demand for PCB boards is increasing daily, placing higher demands on the automation level, stacking accuracy, and production continuity of stacking devices. Automatic feeding, precise positioning, batch stacking, and rapid switching of stacking racks are required to improve production efficiency and ensure board quality.

[0003] Currently, most traditional PCB board stacking devices do not have a dedicated repositioning structure. After a set of boards is stacked, the machine needs to be stopped to disassemble the stacking rack and then replace it with an empty rack. This results in long waiting times and poor production continuity. In view of this, we propose a PCB board stacking device. Utility Model Content

[0004] The main objective of this invention is to provide a PCB board stacking device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the PCB board stacking device proposed in this utility model includes a machine base, a conveyor roller frame fixedly connected to the outer wall of the machine base, a feeding component mounted on the conveyor roller frame, a lifting component mounted on the machine base, and a transposition component mounted on the machine base. The transposition component includes: A shifting side platform is fixedly connected to the outer wall of the machine tool, and a first slide rail is fixedly connected to the top of the shifting side platform. A shifting slide is slidably connected to the top of the first slide rail, and a ring rail is fixedly connected to the top of the shifting slide. A stacking rack is slidably connected to the top of the ring rail, and the stacking rack has a placement slot.

[0006] Preferably, the transposition slide plate has directional holes, and there are four sets of directional holes distributed equidistantly in a circle. The directional rod can slide into the directional holes. The transposition slide plate has threaded through holes, and the threaded through holes are threaded with abutment screws.

[0007] Preferably, the outer wall of the stacking rack is fixedly connected to a support lug, and the inner wall of the support lug is inserted with a directional rod. The directional rod has a T-shaped design, and the support lug and the directional rod are elastically connected by a compression spring.

[0008] Preferably, the feeding assembly includes a mounting frame, the outer wall of which is fixedly connected to the outer wall of the conveyor roller frame, and a first electric cylinder seat is fixedly connected to the top of the mounting frame, with a push block fixedly connected to the output end of the first electric cylinder seat.

[0009] Preferably, a guide plate is fixedly installed on the top of the conveyor roller frame, a feeding baffle is fixedly installed on the top of the conveyor roller frame, and a sensor is installed on the guide plate to monitor whether material is coming.

[0010] Preferably, the lifting assembly includes a second electric cylinder base, the bottom of which is fixedly connected to the inner wall of the machine tool, a lifting platform is fixedly connected to the top of the second electric cylinder base, a guide slide rod is fixedly connected to the bottom of the lifting platform, and a fixing sleeve is fixedly connected to the inner wall of the machine tool.

[0011] Preferably, the top of the lifting platform is fixedly connected to a second slide rail, and the outer wall of the guide slide rod is slidably connected to the inner wall of the fixed sleeve.

[0012] This utility model provides a PCB board stacking device. It has the following beneficial effects: (1) When a set of stacking racks is full, the lifting platform rises to be flush with the transposition side platform. Loosening the abutment screws allows the transposition slide to be pushed along the first slide rail and the second slide rail to switch to the transposition side platform. At the same time, the transposition slide of another set of empty stacking racks is moved to the lifting platform and the abutment screws are tightened to complete the fixation. There is no need to stop the machine to wait throughout the process, ensuring that the stacking work can be carried out continuously and avoiding production interruption.

[0013] (2) The PCB board stacking device guides the PCB board to be transported in a straight line through the guide side plate. The sensor and the feeding baffle work together to achieve precise positioning. The first electric cylinder seat drives the push block to push the board smoothly into the placement slot of the stacking rack. The lifting component automatically adjusts the height according to the stacking progress, so that the empty placement slot is always in the receiving area. No manual intervention is required for feeding and stacking, which greatly improves the batch stacking efficiency of PCB boards. Attached Figure Description

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.

[0019] Please see Figure 1 - Figure 4This utility model proposes a PCB board stacking device, including a machine base 1. A conveyor roller frame 2 is fixedly connected to the outer wall of the machine base 1. The conveyor roller frame 2 is a metal frame with multiple sets of rotating rollers inside. The rollers have smooth surfaces, which can stably convey PCB boards and avoid scratching the board surface. A feeding component 3 is provided on the conveyor roller frame 2. A lifting component 4 is provided on the machine base 1. A switching component 5 is provided on the machine base 1. The switching component 5 includes a switching side platform 51, which is a rectangular metal platform fixedly connected to the outer wall of the machine base 1 and welded to the machine base 1. The first slide rail 52 is fixedly connected to the top of the transposition side platform 51. The transposition slide plate 53 is slidably connected to the top of the first slide rail 52. The transposition slide plate 53 has a threaded through hole and a connecting screw is threaded onto the threaded through hole. By tightening the connecting screw, it abuts against the first slide rail 52 or the second slide rail 45, thus completing the fixing of the transposition slide plate 53. The top of the transposition slide plate 53 is fixedly connected to the ring rail 54. The top of the ring rail 54 is slidably connected to the stacking rack 55. The stacking rack 55 has a placement groove 56.

[0020] In this invention, the repositioning slide plate 53 has four sets of directional holes 57, which are equidistantly distributed in a circle. The directional rod 59 can slide into the directional hole 57 to ensure accurate rotation and positioning of the stacking rack 55. The outer wall of the stacking rack 55 is fixedly connected to the support lug 58, and the inner wall of the support lug 58 is inserted with the directional rod 59. The directional rod 59 has a T-shaped design. The support lug 58 and the directional rod 59 are elastically connected by a compression spring. The compression spring is built between the T-shaped end of the support lug 58 and the directional rod 59. In the natural state, the directional rod 59 is pushed into the directional hole 57 to automatically fix the stacking rack 55. When it is necessary to change the direction, the stacking rack 55 can be rotated by moving the directional rod 59 away from the directional hole 57, and the ring rail 54 provides auxiliary guidance.

[0021] Furthermore, the feeding assembly 3 includes a mounting frame 31, which is an L-shaped metal frame welded and fixed to the conveyor roller frame 2. It has high strength and provides stable support for the first electric cylinder seat 32. The outer wall of the mounting frame 31 is fixedly connected to the outer wall of the conveyor roller frame 2. The top of the mounting frame 31 is fixedly connected to the first electric cylinder seat 32, which is a servo electric cylinder with precise and controllable output stroke. It can stably control the movement of the push block 33. The output end of the first electric cylinder seat 32 is fixedly connected to the push block 33. The top of the conveyor roller frame 2 is fixedly installed with a guide plate 34 and a feeding baffle 35. A sensor is installed on the guide plate 34 to monitor whether material is coming.

[0022] Furthermore, the lifting assembly 4 includes a second electric cylinder base 41, the bottom of which is fixedly connected to the inner wall of the machine base 1. The second electric cylinder base 41 is a servo electric cylinder with precise and controllable output stroke. A lifting platform 42 is fixedly connected to the top of the second electric cylinder base 41, and a guide slide rod 43 is fixedly connected to the bottom of the lifting platform 42. The guide slide rod 43 is a cylindrical metal rod, and two sets are symmetrically distributed to ensure that the lifting platform 42 lifts and lowers smoothly without tilting. A fixed sleeve 44 is fixedly connected to the inner wall of the machine base 1, and a second slide rail 45 is fixedly connected to the top of the lifting platform 42. The second slide rail 45 is a metal rail with the same size as the first slide rail 52 to ensure smooth switching of the shifting slide plate 53. The outer wall of the guide slide rod 43 is slidably connected to the inner wall of the fixed sleeve 44. The fixed sleeve 44 is a cylindrical metal sleeve with a clearance of ≤0.05mm between it and the guide slide rod 43, providing directional support for the guide slide rod 43.

[0023] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0024] In use, the PCB board is conveyed from one side to the other through the conveyor roller frame 2. It is first detected by the diffuse reflection photoelectric sensor on the guide side plate 34. Then, when the board is blocked by the feeding baffle 35, it is also detected by the diffuse reflection photoelectric sensor on the feeding baffle 35. The conveyor roller frame 2 stops conveying. Then, the first electric cylinder seat 32 is activated, which drives the push block 33 to push the board into the upper transfer slide 53 of the lifting platform 42 and push it into the placement slot 56 of the stacking rack 55. Then, the first electric cylinder seat 32 is reset. After the first electric cylinder seat 32 is reset, the second electric cylinder seat 41 moves upward to facilitate the movement of another set of empty placement slots 56 to the receiving area for the next receiving operation. Repeat the above steps. When the placement slots 56 on the stacking rack 55 are full of materials, the height of the lifting platform 42 is the same as the height of the switching side platform 51. Through the cooperation of the first slide rail 52 and the second slide rail 45, we can push the switching slide plate 53 to slide and transfer it to a set of switching side platforms 51. Then move the switching slide plate 53 on another set of switching side platforms 51. By rotating the abutment screw, we can easily loosen and fix the switching slide plate 53 and move it to the lifting platform 42 with the empty stacking rack 55. Then start the second electric cylinder base 41 to lower the lifting platform 42 to facilitate the new material receiving work.
