Description

Technical Field

[0001] This utility model relates to the technical field of PCB feeding equipment, specifically an automatic PCB feeder. Background Technology

[0002] PCB feeders are key pieces of equipment used in PCB manufacturing. They automatically transport PCB boards and are equipped with an adjustment mechanism. A motor-driven lead screw moves related components, allowing the T-shaped pallet to move along the inclined guide plate and groove. This, in turn, moves the limit rods and other components to adjust the position, enabling precise adjustment of the feeding limit to accommodate PCBs of different sizes. It also prevents damage to the end face of the processed board. The feeding mechanism uses an electro-hydraulic rod to drive a lifting plate and a suction cup to pick up and transport the processed board. For flexible PCBs, an electric push rod lifts the middle of the plate into an arc shape, ensuring that only one board is transported at a time, improving feeding accuracy and production efficiency.

[0003] In addition, most early PCB feeders used fixed limiting devices, which meant they could only be used for PCBs of specific sizes. When processing products of different sizes, they were not convenient to operate. Furthermore, traditional feeding methods usually used a simple suction cup adsorption principle. When dealing with flexible PCBs, this method could easily cause multiple PCBs to stick together. Therefore, it was necessary to design an automatic PCB feeder that could solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic PCB feeder to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic PCB feeder, including a machine base, wherein adjustment mechanisms are fixedly connected to the front and rear ends of the machine base respectively, and a feeding mechanism is fixedly connected to the top of the machine base.

[0006] The adjustment mechanism includes two support seats, which are fixedly connected to the front and rear ends of the machine base respectively. A slanted guide plate is fixedly connected to the top of one side of each support seat. A guide seat is provided on the surface of the support seat. A motor is fixedly connected to the front of the guide seat. A lead screw is fixedly connected to one end of the back of the motor. A threaded block is threaded onto the surface of the lead screw. A T-shaped clamping plate is fixedly connected to the top of the threaded block. A limit rod is fixedly connected to the side of the guide seat. A vertical seat is fixedly connected to one end of the limit rod. A limit rod is fixedly connected to the bottom of the side of the support seat. A spring is fixedly connected inside the vertical seat. A limit plate is fixedly connected to the top of the spring. A vertical rod is fixedly connected to the top of the limit plate. A top bar is fixedly connected to the top of the vertical rod. A feeding roller is fixedly connected to the top right of the machine base. A limit bar is fixedly connected to the bottom of the side of the support seat.

[0007] Preferably, a guide groove is formed inside the guide seat, and the surface of the threaded block is slidably connected to the inside of the guide groove, so that the threaded block can slide inside the guide groove.

[0008] Preferably, a limiting hole is formed inside the bottom end of the guide seat, and the surface of the limiting rod is slidably connected to the limiting hole. A rectangular hole is formed inside the support seat, and the surface of the limiting rod is slidably connected to the rectangular hole.

[0009] Preferably, the inclined guide plate has an inclined groove inside, and the upper surface of the T-shaped card plate is slidably connected to the inside of the inclined groove, so that the T-shaped card plate can slide under the trajectory action in the inclined groove.

[0010] Preferably, a limiting groove is formed inside the vertical seat, and the surface of the limiting plate is slidably connected to the inside of the limiting groove.

[0011] Preferably, the feeding mechanism includes an electric slide rail assembly, which is fixedly connected to the top of the machine base. An electric hydraulic rod is fixedly connected to the bottom end of the electric slide rail assembly, and a lifting plate is fixedly connected to the bottom end of the electric hydraulic rod. An electric push rod is fixedly connected to the inside of one end of the lifting plate, and a stop block is fixedly connected to the bottom end of the electric push rod. Suction cup assemblies are fixedly connected to the four ends of the surface of the electric hydraulic rod.

[0012] Preferably, the lifting plate has a through hole at each of its four ends, the surface of the suction cup assembly is fixedly connected to the inside of the through hole, and a second through hole is opened at one end of the middle of the lifting plate, the surface of the electric push rod is slidably connected to the inside of the second through hole, so as to facilitate the electric push rod to perform support activities within the second through hole.

[0013] Compared with the prior art, the present invention provides an automatic PCB feeder, which has the following advantages:

[0014] 1. This automatic PCB feeder, through an adjustable mechanism, uses a motor-driven lead screw to rotate. The rotation of the lead screw causes the mating threaded block and T-shaped clamping plate to move synchronously. During this process, the T-shaped clamping plate moves along a specific trajectory of the inclined groove inside the inclined guide plate, thereby pushing the limit rod to move. The movement of the limit rod further drives the vertical seat and movable plate to adjust their positions, achieving precise adjustment of the PCB board feeding limit. This design allows the feeder to flexibly adapt to the feeding limit requirements of PCB boards of different sizes and effectively avoids damage to the end face of the PCB board caused by excessive clamping adjustment force.

[0015] 2. This automatic PCB feeder, through its feeding mechanism, uses an electric hydraulic rod to drive a lifting plate downwards, which in turn drives a suction cup assembly downwards to adsorb the PCB processing board. This adsorbs the processing board and lifts it upwards for transport. During the upward lifting process, since the PCB processing board is made of a soft material, an electric push rod drives a stop block downwards, pushing the center of the processing board downwards to a certain degree of arc. This allows excess processing boards to be returned to their original position, ensuring that only one PCB processing board is transported at a time, thus avoiding the phenomenon of multiple processing boards sticking together.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Combination Figures 2 to 6 PCB automatic feeder includes a machine base 1, with adjustment mechanisms 2 fixedly connected to the front and rear ends of the machine base 1, and a feeding mechanism 3 fixedly connected to the top of the machine base 1.

[0029] The adjusting mechanism 2 includes a support base 21, of which there are two. The two support bases 21 are fixedly connected to the front and rear ends of the machine base 1, respectively. An inclined guide plate 22 is fixedly connected to the top of one side of the support base 21. A guide seat 23 is provided on the surface of the support base 21. A motor 231 is fixedly connected to the front of the guide seat 23. A lead screw 24 is fixedly connected to one end of the back of the motor 231. A threaded block 25 is threadedly connected to the surface of the lead screw 24. A T-shaped clamping plate 26 is fixedly connected to the top of the threaded block 25. A limit rod 232 is fixedly connected to the side of the guide seat 23. A vertical seat 27 is fixedly connected to one end of the limit rod 232. A limit rod 24 is fixedly connected to the bottom of the side of the support base 21. 32. A spring 271 is fixedly connected inside the vertical base 27. A limit plate 28 is fixedly connected to the top of the spring 271. A vertical rod 281 is fixedly connected to the top of the limit plate 28. A top bar 282 is fixedly connected to the top of the vertical rod 281. A feeding roller 29 is fixedly connected to the top right of the machine base 1. A limit bar 233 is fixedly connected to the bottom side of the support base 21. A guide groove is opened inside the guide base 23. The surface of the threaded block 25 is slidably connected to the inside of the guide groove. A limit hole is opened inside the bottom of the guide base 23. The surface of the limit bar 233 is slidably connected to the inside of the limit hole. A rectangular hole is opened inside the support base 21. The surface of the limit bar 232 is slidably connected to the inside of the rectangular hole.

[0030] Furthermore, an inclined groove is formed inside the inclined guide plate 22, and the upper surface of the T-shaped clamping plate 26 is slidably connected to the inside of the inclined groove. A limiting groove is formed inside the vertical seat 27, and the surface of the limiting plate 28 is slidably connected to the inside of the limiting groove. The motor 231 drives the lead screw 24 to rotate, which in turn drives the threaded block 25 and the T-shaped clamping plate 26 to move. Thus, the T-shaped clamping plate 26 drives the limiting rod 232 to move under the trajectory of the inclined groove inside the inclined guide plate 22, which in turn drives the vertical seat 27 and the movable plate 291 to move and adjust the feeding limit of the PCB processing board. This makes it suitable for feeding limit of PCB processing boards of different sizes.

[0031] Example 2

[0032] See Figure 1-6 Furthermore, based on Embodiment 1, the feeding mechanism 3 further includes an electric slide rail assembly 31, which is fixedly connected to the top of the machine base 1. An electric hydraulic rod 32 is fixedly connected to the bottom of the electric slide rail assembly 31, and a lifting plate 33 is fixedly connected to the bottom of the electric hydraulic rod 32. An electric push rod 34 is fixedly connected to the inside of one end of the lifting plate 33, and a stop block 35 is fixedly connected to the bottom of the electric push rod 34. Suction cup assemblies 36 are fixedly connected to the four ends of the surface of the electric hydraulic rod 32.

[0033] Furthermore, the lifting plate 33 has four through holes at its four ends. The surface of the suction cup assembly 36 is fixedly connected to the inside of the through hole one. The lifting plate 33 has a through hole two at one end in the middle. The surface of the electric push rod 34 is slidably connected to the inside of the through hole two. The electric hydraulic rod 32 drives the lifting plate 33 downward and drives the suction cup assembly 36 downward to adsorb the PCB processing board, thereby adsorbing the processing board and lifting it upward for corresponding transport. During the upward lifting of the processing board, since the PCB processing board is made of soft material, the electric push rod 34 drives the stop block 35 downward to push the middle of the processing board downward to a certain degree of arc, thereby returning the excess processing board to its original position, thus ensuring that only one PCB processing board is transported at a time.

[0034] In actual operation, when this device is used, during the feeding operation of PCB processing boards, multiple pre-processed PCB processing boards are neatly stacked on the feeding roller 29. Then, in order to keep the feeding position of the processed parts accurate during feeding, it is necessary to limit the left and right ends of the processing board. The vertical seat 27 and the movable plate 291 are moved to limit the contact between the two ends of the stacked processing parts and ensure the limit is maintained. Then, during feeding, the electric hydraulic rod 32 drives the lifting plate 33 downward and drives the suction cup assembly 36 downward to adsorb the PCB processing board, thereby adsorbing the processing board and lifting it upward for corresponding conveying. During the upward lifting of the processing board, since the PCB processing board is made of soft material, the electric push rod 34 drives the abutment block 35 downward to push the middle of the processing board downward to a certain degree of arc, thereby returning the excess processing board to its original position, thus ensuring that only one PCB processing board is conveyed at a time.

[0035] In addition, when the feeding limit of the PCB processing board needs to be adjusted for the clamping size of processing boards of different sizes, the motor 231 drives the lead screw 24 to rotate, which in turn drives the threaded block 25 and the T-shaped clamping plate 26 to move. This allows the T-shaped clamping plate 26 to drive the limit rod 232 to move under the action of the inclined groove inside the inclined guide plate 22, which in turn drives the vertical seat 27 and the movable plate 291 to move and adjust the feeding limit of the PCB processing board. This is suitable for feeding limit of PCB processing boards of different sizes. In addition, when the lifting plate 33 moves downward, it contacts the top of the top bar 282 and drives the movable plate 291 to move downward. The vertical mobility of the movable plate 291 can ensure the normal lifting and lowering of the lifting plate 33, and the suction cup assembly 36 is long enough to adsorb the bottom processing board.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
