Description

Technical Field

[0001] This utility model relates to the field of PCB board production equipment, specifically an automated equipment for double-sided inlay welding of PCB boards. Background Technology

[0002] PCBs can be classified according to the number of circuit layers into single-sided boards, double-sided boards, four-layer boards, six-layer boards, and other multi-layer circuit boards. Double-sided boards: These circuit boards have wiring on both sides, but to use the wires on both sides, there must be appropriate circuit connections between the two sides.

[0003] In the PCB manufacturing process, automated double-sided inlay soldering equipment is indispensable. This type of equipment is typically equipped with robotic arms for gripping PCB substrates for loading and flipping operations. It also includes feeding mechanisms and soldering mechanisms for soldering components. Traditionally, the loading process relied on robotic arms gripping at fixed points, while manual labor was responsible for loading at these points. Because loading required waiting for the robotic arms to operate, manual monitoring was necessary for extended periods, consuming significant time and increasing labor costs. Utility Model Content

[0004] The purpose of this invention is to provide an automated PCB board double-sided inlay welding equipment that eliminates the need for long-term, continuous manual monitoring of material feeding, thereby saving manpower and time, and can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated PCB board double-sided inlay welding equipment, comprising a housing and an internal loading structure. The loading structure includes a rotating shaft. The top of the housing is open. Two sets of rotating shafts are arranged parallel to each other inside the housing. Each set contains several rotating shafts, which are arranged vertically along the housing. The two ends of the rotating shafts are rotatably connected to adjacent sides inside the housing. Two sets of loading rods are fixedly connected to the annular side of the rotating shaft. Each set contains two loading rods. The outer walls of the rotating shaft are annularly arranged with the two loading rods. Support rods are rotatably mounted on both ends of the rotating shaft. The two support rods are symmetrically arranged about the loading rods. Limiting rods are fixedly connected to the front door and rear side of the housing above the support rods. Several evenly arranged elongated channels are opened on the front side of the housing. A drive structure is installed at the bottom of the housing.

[0006] Preferably, the top of both the front and rear sides of the housing is provided with notches.

[0007] Preferably, the front inner side of the box body located in the long channel position is fixedly connected with a baffle.

[0008] Preferably, the bottom of the housing is equipped with several locking casters.

[0009] Preferably, the drive structure includes a stepper motor, which is installed on the rear end face at the bottom of the housing. The output end of the stepper motor is connected to the main shaft. Two drive wheels are fixedly sleeved on the main shaft. Driven wheels are fixedly sleeved on the outer walls of the two shafts located at the lowest position. The drive wheels are connected to the driven wheels through a first belt. Each set of shafts has a pulley fixedly sleeved on the outer wall. The pulleys in the same vertical direction are connected through a second belt.

[0010] Preferably, one end of the support rod is located near the limiting rod, and its weight is less than that of the other end of the support rod, and the two vertically adjacent feeding rods are staggered.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The system enables the synchronous upward movement of each PCB substrate. Once the top PCB substrate is removed, the PCB substrates below are replenished. This process does not require long-term manual monitoring of the feeding, thus saving manpower and time. It allows operators to supervise other equipment or perform other replenishment work, effectively reducing labor costs. Furthermore, the system uses a vertical stacking method for feeding multiple PCB substrates, which takes up less space compared to the flat conveyor belt method. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1 , Figure 3 and Figure 4 The diagram illustrates an automated double-sided PCB soldering equipment, comprising a housing 1 and an internal loading structure 2. The loading structure 2 includes rotating shafts 201. The top of the housing 1 is open, and two sets of rotating shafts 201 are arranged parallel to each other inside the housing 1. Each set contains several rotating shafts 201, which are distributed vertically along the housing 1. The two ends of each rotating shaft 201 are rotatably connected to adjacent sides of the housing 1, and the annular side of each rotating shaft 201 is fixedly connected. Two sets of feeding rods 203 are connected, with two feeding rods 203 in each set. The two feeding rods 203 are arranged in a ring on the outer wall of the rotating shaft 201. There are support rods 202 on the rotating sleeves at both ends of the rotating shaft 201. The two support rods 202 are symmetrically arranged about the feeding rods 203. Limiting rods 204 are fixedly connected to the front door and rear side of the box 1 above the support rods 202. Several evenly arranged long channels 102 are opened on the front side of the box 1. A drive structure 3 is installed at the bottom of the box 1.

[0020] It is worth noting that when the box 1 is placed at the gripping and loading position of the robotic arm, the operator only needs to insert multiple PCB substrates from the long channel 102 into the area of ​​the support rod 202 at once. The support rod 202 then lifts the PCB substrates, activating the drive structure 3, which causes several rotating shafts 201 to rotate synchronously. The rotation of the rotating shafts 201 simultaneously drives the loading rod 203 to rotate. When the loading rod 203 contacts the bottom of the PCB substrate, it lifts the PCB substrate upward. As the PCB substrate rises, it squeezes the support rod 202, causing it to rotate upward. Since the extension length of the support rod 202 is less than that of the loading rod... With the extension length of 203, the support rod 202 will detach from the side wall of the PCB substrate before it. Under the influence of gravity, the support rod 202 will fall back to its original position. The feeding rod 203 continues to rotate and eventually detaches from the bottom of the PCB substrate. The PCB substrate then falls to the support rod 202 at the upper position, realizing the synchronous upward movement of each PCB substrate. When the topmost PCB substrate is removed, the replenishment process of the PCB substrates below is completed. This process does not require long-term continuous monitoring of the feeding, thus saving manpower and time, allowing operators to supervise other equipment or perform other replenishment work, effectively reducing labor costs.

[0021] Please see Figure 4The box 1 has notches 101 on the top of both the front and rear sides. It is worth noting that the robotic arm can grab the PCB substrate at the top position through the notches 101.

[0022] See Figure 1 The front inner side of the box 1 is fixedly connected with a baffle 103 at the position of the long channel 102. The baffle 103 is made of rubber material. The baffle 103 closes the area of ​​the long channel 102 and prevents the PCB board placed in the box 1 from sliding out during the collision process.

[0023] See Figure 1 and Figure 2 The bottom of the box 1 is equipped with several locking casters 104. It is worth noting that the box can be moved to a suitable position by relying on the locking casters 104, so as to fix the loading position and increase the applicability.

[0024] See Figure 2 and Figure 3 The drive structure 3 includes a stepper motor 301 and a stepper motor 306 mounted on the rear end face of the bottom position of the housing 1. The output end of the stepper motor 301 is connected to the main shaft 306. The main shaft 306 is fixedly fitted with two drive wheels 304. The outer walls of the two rotating shafts 201 located at the lowest position are fixedly fitted with driven wheels 305. The drive wheels 304 are connected to the driven wheels 305 through a first belt 302. The outer walls of each set of rotating shafts 201 are fixedly fitted with pulleys 307. The pulleys 307 in the same vertical direction are connected through a second belt 303.

[0025] It is worth noting that when the stepper motor 301 is turned on, the main shaft 306 is rotated at a fixed angle. The drive wheel 304 is connected to the driven wheel 305 through the first belt 302, thereby driving the two rotating shafts 201 at the bottom position to rotate synchronously. The pulleys 307 in the same vertical direction are connected through the second belt 303, so that all rotating shafts 201 rotate synchronously. The working frequency of the robotic arm gripping is set to the same as that of the stepper motor 301, ensuring that after gripping, a PCB substrate can be continuously provided to the gripping position.

[0026] See Figure 4 One end of the support rod 202 is located near the limiting rod 204. Its weight is less than that of the other end of the support rod 202. Under its own weight, the support rod 202 will fall back. Through the limiting rod 204, the support rod 202 falls back to a fixed position and stops falling, thus being able to support the PCB substrate to lay flat. The two vertically adjacent feeding rods 203 are staggered, so that the two vertical feeding rods 203 will not collide during the rotation process, ensuring the normal rotation and feeding process.

[0027] Working principle: The box 1 is placed at the gripping and loading position of the robotic arm. The operator simply inserts multiple PCB substrates from the long channel 102 into the support rod 202 area at once. The support rod 202 then lifts the PCB substrates, activating the stepper motor 301, which rotates the main shaft 301 at a fixed angle. The driving wheel 304 is connected to the driven wheel 305 via the first belt 302, thus driving the two bottom rotating shafts 201 to rotate synchronously. Pulleys 307 in the same vertical direction are connected via the second belt 303, causing all rotating shafts 201 to rotate synchronously. This results in a number of rotating shafts 201 rotating simultaneously. The rotation of shaft 201 simultaneously drives the loading rod 203 to rotate. When the loading rod 203 contacts the bottom of the PCB substrate, it lifts the PCB substrate upward. As the PCB substrate rises, it squeezes the support rod 202, causing it to rotate upward. Since the extension length of the support rod 202 is less than the extension length of the loading rod 203, the support rod 202 will detach from its side wall before the PCB substrate. Due to gravity, the support rod 202 will fall back to its original position. The loading rod 203 continues to rotate and eventually detaches from the bottom of the PCB substrate. The PCB substrate then falls to the support rod 202 at the upper position, achieving synchronous upward movement of each PCB substrate.
