Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing, and in particular relates to a feeding and flipping device for processing circuit board substrates. Background Technology

[0002] In the field of PCB substrate processing, the loading and turning device is a key piece of equipment for ensuring the continuity of the production process and processing quality. Its performance directly affects the efficiency and yield of the entire production line. However, the relevant devices currently on the market still have many shortcomings at the technical level that urgently need to be addressed.

[0003] Some devices use a single rotating axis to rotate the substrate, which makes it difficult to maintain the substrate's balance during the rotation process. This is especially true for larger or thinner circuit board substrates, where uneven rotation and poor rotation results are common. Other devices use only vacuum chucks to grip the circuit board substrate. However, due to the limited adhesion between the vacuum chuck and the substrate surface, the substrate cannot be gripped firmly, resulting in poor gripping stability and a high risk of causing hard damage to the substrate during gripping. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a feeding and flipping device for processing circuit board substrates, which aims to solve the problems of poor flipping effect and poor gripping stability of existing feeding and flipping devices for processing circuit board substrates.

[0005] The present invention adopts the following technical solution:

[0006] The feeding and turning device includes a machine base with a pair of front and rear material carriers on the machine base. A turning mechanism is provided between the material carriers. The machine base also includes a transfer mechanism. The turning mechanism includes a fixed base with a pair of partitions above the fixed base. A pair of support seats are slidably mounted on the partitions. Each support seat has a limit groove at its front end. A sliding cylinder is provided on the fixed base corresponding to each support seat. The drive seat of the sliding cylinder is connected to the back of the support seat. A pair of rotating seats are also rotatably mounted on the fixed base between the two partitions. The rotating seats have grippers and driven wheels on their inner and outer sides, respectively. A turning assembly is provided inside the fixed base to drive the driven wheels to rotate.

[0007] Furthermore, the fixed base is provided with a rotating shaft, both ends of which extend out of the fixed base and are provided with driving wheels. A belt is fitted between the driving wheel and the driven wheel on the same side. The flipping assembly includes a gear mounted on the rotating shaft. The fixed base is provided with a slide, and the slide is provided with a connecting seat. The connecting seat is provided with a spur rack, and the spur rack meshes with the gear. The fixed base is also provided with a sliding cylinder, and the drive shaft of the sliding cylinder is connected to the connecting seat.

[0008] Furthermore, the transplanting mechanism includes a horizontal moving module, the moving end of which is provided with a vertical moving module, the moving end of which is provided with a lifting plate, the top surface of which is provided with a top frame, a row of vacuum suction columns inserted downwards through the top of the top frame, the lower end of the vacuum suction columns passing through the lifting plate, and a retaining ring formed in the middle of the vacuum suction columns on the top surface of the lifting plate, and a spring provided on the vacuum suction columns between the retaining ring and the top frame.

[0009] Furthermore, both ends of the lifting plate are provided with corner seats, and the corner seats are provided with stop seats that rotate downwards. The corner seats are also provided with clamping cylinders, and the drive shaft of the clamping cylinders is rotatably connected to the stop seats.

[0010] The beneficial effects of this utility model are:

[0011] 1. In the flipping mechanism of this device, the sliding cylinder can drive the support base to slide on the partition, which makes it easy to adjust the distance between the two support bases according to the size of the circuit board substrate. The limiting groove can play a good limiting role for the substrate, improving the adaptability to substrates of different sizes.

[0012] 2. The flipping assembly moves the connecting seat through a sliding cylinder, causing the rack and pinion drive gear to rotate. This, in turn, drives the rotating seat to rotate through the rotating shaft, drive wheel, belt, and driven wheel, thus enabling the gripper to flip the substrate. This transmission method is relatively smooth and reduces the impact on the substrate during the flipping process.

[0013] 3. The vacuum suction column of the transplanting mechanism can be buffered by the action of the spring, which on the one hand avoids hard damage to the substrate, and on the other hand allows the vacuum suction column to stably grasp the circuit board substrate. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figures 1-4 As shown, the feeding and turning device includes a machine base 1, on which a pair of front and rear material carriers 2 are provided, and a turning mechanism is provided between the material carriers 2. The machine base 1 is also provided with a transfer mechanism. The turning mechanism includes a fixed base 4, and a pair of partitions 5 are provided above the fixed base 4. A pair of support seats 6 are slidably provided on the partitions 5. The front end of each support seat 6 is provided with a limit groove 7. A sliding cylinder 8 is provided on the fixed base 4 corresponding to each support seat. The drive seat of the sliding cylinder 8 is connected to the back of the support seat 6. A pair of rotating seats 3 are also rotatably provided on the fixed base 4 between the two partitions 5. The rotating seats 7 are provided with a clamp 31 and a driven wheel 9 on the inner and outer sides of the fixed base 4, respectively. A turning component is provided inside the fixed base 4. The turning component is used to drive the driven wheel 9 to rotate.

[0022] In this embodiment, the front loading rack is a loading rack, and the rear loading rack is a unloading rack. When using this device, a certain number of substrates are first placed on the loading rack. Then, according to the size of the substrate, the sliding cylinder on the fixed base is activated, driving the support base to slide on the partition, adjusting the distance between two support bases at the same position. Next, the transfer mechanism picks up a substrate from the loading rack and transfers it to the flipping mechanism, allowing the edge of the substrate to be inserted into the limiting groove at the front end of the support base, completing the initial positioning of the substrate. Then, the gripper lightly clamps the substrate. Because the gripping end of the gripper is equipped with a rubber pad, it will not damage the substrate.

[0023] In practice, the machine is also equipped with a processing mechanism to process the substrate. After processing is completed, all the support seats retract to create clearance. Driven by the flipping component, the gripper rotates the substrate 180 degrees, and the support seats move towards the substrate again to support and limit the substrate. The gripper releases to create clearance, and the transfer mechanism transfers the substrate to the unloading rack and stacks it neatly as required.

[0024] As a preferred structure, such as Figures 2-3The fixed base 4 is provided with a rotating shaft 10. Both ends of the rotating shaft 10 extend out of the fixed base 4 and are provided with driving wheels 11. A belt 12 is fitted between the driving wheel 11 and the driven wheel 9 on the same side. The flipping assembly includes a gear 13 installed on the rotating shaft 10. The fixed base 4 is provided with a slide 14. The slide 14 is provided with a connecting seat 15. The connecting seat 15 is provided with a spur rack 16, and the spur rack 16 meshes with the gear 13. The fixed base 4 is also provided with a sliding cylinder 17. The drive shaft of the sliding cylinder 17 is connected to the connecting seat 15.

[0025] When the flipping assembly drives the gripper to flip, the sliding cylinder drives the connecting seat to move on the slide, and the rack inside the connecting seat moves accordingly. Since the rack meshes with the gear on the rotating shaft, the gear drives the rotating shaft to rotate, and the driving wheels at both ends of the rotating shaft also rotate synchronously. Through belt transmission, the driving wheel drives the driven wheel on the same side to rotate, thereby causing the rotating seat to rotate. The gripper rotates with the rotating seat, realizing the flipping of the substrate.

[0026] Furthermore, as a preferred structure, combined with Figure 1 , Figure 4 The transplanting mechanism includes a horizontal moving module 18, and a vertical moving module 19 is provided at the moving end of the horizontal moving module 18. A lifting plate 20 is provided at the moving end of the vertical moving module 19. A top frame 21 is provided on the top surface of the lifting plate 20. A row of vacuum suction columns 22 is inserted downwards through the top of the top frame 21. The lower end of the vacuum suction column 22 passes through the lifting plate 20, and a retaining ring 23 is formed in the middle of the vacuum suction column 22 on the top surface of the lifting plate. A spring 24 is provided on the vacuum suction column between the retaining ring and the top frame.

[0027] When the processed carrier plate is transferred to the unloading rack using the transfer mechanism, the lateral movement module drives the vertical movement module to move above the substrate. The vertical movement module then drives the lifting plate to descend, bringing the lower end of the vacuum suction column into contact with the substrate. Through vacuum adsorption, the vacuum suction column holds the substrate. During the contact process between the vacuum suction column and the substrate, the spring is compressed, which serves two purposes: firstly, to cushion the impact and prevent hard damage to the substrate, and secondly, to allow the vacuum suction column to grip the substrate more stably. After the substrate is gripped, the lifting plate moves upward, and the lateral movement module moves the lifting plate directly above the unloading rack. Finally, the lifting plate moves downward and neatly stacks the substrate on the unloading rack. Since the vertical and lateral movement modules are existing technologies, they will not be described in detail here.

[0028] In addition, both ends of the lifting plate 20 are provided with corner seats 25, and the corner seats 25 are rotatably provided with stop seats 26. The corner seats 25 are also provided with clamping cylinders 27, and the drive shaft of the clamping cylinders 27 is rotatably connected to the stop seats 26.

[0029] Once the substrate is picked up, the lifting plate moves up a short distance, the clamping cylinder is activated, and the stop seat rotates. The stop seat contacts the side of the substrate, further securing the substrate and preventing it from falling during the transfer process.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
