Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing and processing equipment technology, and in particular to a PCB pin removal device. Background Technology

[0002] In PCB (Printed Circuit Board) manufacturing, pins are used to secure the PCB board and ensure its stability during processing or transportation. However, these pins need to be removed in subsequent processes for further processing or packaging. Traditional pin removal methods rely heavily on manual operation, which is inefficient.

[0003] To address the aforementioned issues, some improvements have been proposed in the prior art. For example, patent application CN107932037A discloses a PCB board shape positioning pin removal device, including a support frame, a controller, a hydraulic push device, and a pin clamp. The controller is embedded in the upper side of the support frame and is electrically connected to the hydraulic push device. The hydraulic push device is embedded in the middle side of the support frame, and the pin clamp is embedded in the lower side. The controller controls the hydraulic actuator of the hydraulic push device to drive the lower telescopic rod to move up and down, thereby clamping and moving the pin clamp at the bottom. The sliding device of the clamp drives the pin removal plate to fix the pin, and the hydraulic push device pulls it out. This improves the efficiency of pin removal, does not damage the PCB board, and saves manpower.

[0004] While the existing technology can automatically remove pins, it does not address issues such as how to feed and position the PCB board, or how to collect the pins. Therefore, there is an urgent need for a fully automated device that can automatically feed, position, remove, and collect the pins of the PCB board to solve these problems. Utility Model Content

[0007] A PCB pin removal device includes a mounting base, which is equipped with a conveying mechanism, a limiting mechanism, a pin removal mechanism, and a collecting mechanism. The conveying mechanism includes multiple conveying rollers and a drive assembly for rotating the conveying rollers. The limiting mechanism includes limiting wheel sets disposed on both sides of the conveying mechanism. Each limiting wheel set includes several limiting wheels. Multiple limiting wheel sets are arranged along the conveying direction.

The movable seat is threadedly connected to the lead screw and slidably connected to the guide shaft.

[0010] Furthermore, the angle adjustment assembly includes a rotating shaft rotatably connected to the lateral adjustment assembly. The rotating shaft is fixedly connected to a rotating seat.

[0011] Furthermore, the collection mechanism includes a collection box disposed at the lower end of the nail-pulling mechanism.

[0012] Furthermore, the distance between the conveying rollers on both sides of the lower end of the nail puller is greater than the distance between the other conveying rollers.

[0013] Furthermore, a guide roller is provided between the conveying rollers on both sides of the lower end of the nail puller, and the guide roller and the nail puller are located at different positions in the width direction of the conveying mechanism.

[0026] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1-4As shown, a PCB pin removal device includes a mounting base, which is provided with a conveying mechanism 1, a limiting mechanism 2, a pin removal mechanism 3, and a collecting mechanism 4. The conveying mechanism 1 includes multiple conveying rollers 11 and a driving assembly for driving the conveying rollers 11 to rotate. The limiting mechanism 2 includes limiting wheel sets 21 arranged on both sides of the conveying mechanism 1. Each limiting wheel set 21 includes several limiting wheels 211. Multiple limiting wheel sets 21 are arranged along the conveying direction. The gap between the limiting wheels 211 at the front end of the conveying mechanism 1 gradually decreases to the width of the PCB board, and the gap between the limiting wheels 211 at the rear end of the conveying mechanism 1 is equal to the width of the PCB board. The pin removal mechanism 3 is provided in two sets, respectively arranged on both sides of the rear end of the conveying mechanism. The pin removal mechanism 3 includes a position adjustment assembly, a hydraulic pushing device 31, and a pin remover 32. The pin remover 32 is arranged at the upper end between adjacent conveying rollers 11.

[0029] The conveying mechanism 1 is used for automatically conveying PCB boards. The conveying rollers 11 and drive assembly ensure smooth movement of the PCB boards, improving production efficiency. The limiting mechanism 2 uses limiting wheel sets 21 to position the PCB boards, ensuring accurate positioning during conveying and preventing deviation. The pin removal mechanism 3 uses a hydraulic push device 31 to drive the pin remover 32, enabling quick and stable removal of pins, ensuring complete removal without damaging the PCB board. The collecting mechanism 4 collects the removed pins, preventing them from scattering and causing injury to equipment or operators. The pin remover 32 can utilize existing technologies.

[0030] Furthermore, the limiting wheel assembly 21 includes a lateral adjustment component 212 and an angle adjustment component 213. The lateral adjustment component 212 and the angle adjustment component 213 cooperate to gradually reduce the gap between the front limiting wheels 211.

[0031] Furthermore, the transverse adjustment assembly 212 includes a lead screw 2121, a guide shaft 2122, a first rotating handle 2123, a movable seat 2124, and a mounting groove 2125. The lead screw 2121 is rotatably disposed within the mounting groove 2125 perpendicular to the conveying direction. One end of the lead screw 2121 moves to the outer end of the mounting groove and is fixedly connected to the first rotating handle 2123. The guide shaft 2122 is arranged parallel to the lead screw 2121. The movable seat 2124 is threadedly connected to the lead screw and slidably connected to the guide shaft. The transverse adjustment assembly 212 achieves precise movement of the movable seat 2124 through the lead screw 2121 and the guide shaft 2122. The first rotating handle 2123 facilitates manual adjustment, improving the versatility and ease of operation of the equipment.

[0032] Furthermore, the angle adjustment assembly 213 includes a rotating shaft 2131 rotatably connected to the transverse adjustment assembly 212. The rotating shaft 2131 is fixedly connected to a rotating seat 2132. A groove is formed on the inner side of the rotating seat 2132. The rotating shaft 2131 extends through the groove to the outer end of the rotating seat 2132 and is connected to a second rotating handle 2133. Multiple limiting wheels 211, whose circumferential planes are parallel to the horizontal plane, are rotatably arranged within the groove. The angle adjustment assembly 213 also includes a locking element 2134, which is a threaded rod that is interference-fitted with the rotating shaft 2131. A third rotating handle 2135 is provided at one end of the threaded rod. The angle adjustment assembly 213 achieves angle adjustment of the limiting wheels 211 through the rotating shaft 2131 and the rotating seat 2132. The second rotating handle 2133 facilitates manual operation, and the locking element 2134 is used to fix the adjusted angle, ensuring the PCB board remains stable during transport and preventing tilting or displacement.

[0033] Furthermore, the collection mechanism 4 includes a collection box 41 disposed at the lower end of the pin removal mechanism. The collection box 41 is used to collect the removed pins, preventing them from scattering and causing injury to the equipment or operators, while also keeping the working environment clean.

[0034] Furthermore, the distance between the conveying rollers 11 on both sides of the lower end of the nail puller 32 is greater than the distance between the other conveying rollers. This provides sufficient space for the rear pin of the nail puller 32 to fall into the collection box.

[0035] Furthermore, a guide roller 12 is also provided between the conveying rollers 11 on both sides of the lower end of the pin puller 32. The guide roller 12 and the pin puller 32 are located at different positions in the width direction of the conveying mechanism. Since the gap between the conveying rollers 11 is relatively large to provide space for the pins to fall, it is easy to cause unstable PCB board conveying. Therefore, the guide roller 12 is provided at a position away from the pin puller 32.

[0036] Furthermore, the two sets of nail-pulling mechanisms 3 are arranged in different length directions of the conveying mechanism 1, which increases the length of the guide roller and disperses the space.

[0037] Furthermore, the position adjustment component adopts a lead screw structure, which can realize precise position adjustment of the pin puller 32, ensuring that the pin puller 32 can accurately align with the pin, improving the success rate and efficiency of pin removal, and can be applied to different PCB boards.

[0038] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
