TECHNICAL FIELD
[0001] The utility model relates to pin selection technical field especially relates to a PCB forming pin selection device. BACKGROUND
[0002] In the process of PCB circuit board forming manufacturing, different product designs will use various specifications of pins in the forming positioning process. The pins mainly play a role in fixing and positioning in the process of circuit board forming manufacturing, ensuring that the wires and components on the circuit board can be firmly and stably connected.
[0003] In the existing pin selection process, different specifications of pins will be mixed together after use and cannot be quickly distinguished, which will cause errors in the next use process and ultimately lead to product size problems due to the use of incorrect pin specifications. To ensure that the forming processing size meets the requirements, the existing PCB forming processing will use a caliper to measure each pin before use. This existing PCB measurement method has slow measurement efficiency, resulting in low forming efficiency and machine utilization rate.
[0004] The problem of needing to measure the pins by using a caliper by hand and then sorting them in the above-mentioned scheme is solved by the layered design of the upper and lower layers, and the installation of a baffle with an opening the same size as the small pins in the middle. The small pins are made to fall into the lower sorting box through the opening by manually shaking the lower baffle, thereby achieving the effect of sorting pins of different sizes.
[0005] However, in the above-mentioned sorting process, manual shaking may result in uneven shaking and require a high level of personnel work difficulty. The pins need to be shaken continuously by hand, and when multiple different pins are mixed, the pins need to be sorted multiple times by replacing the baffle, which may cause problems such as high worker operation difficulty and excessive physical consumption. INVENTION CONTENTS
[0006] The utility model aims at solving the shortcomings in the prior art and provides a PCB forming pin selection device, which solves the technical problem of how to reduce the worker operation difficulty and excessive physical consumption.
[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0008] A PCB forming pin selection device, comprising a top frame, a limiting sliding groove is formed in the inside of the top frame, a baffle is slidingly connected to the upper end of the limiting sliding groove, a plurality of sorting openings are uniformly formed in the top end of the baffle, and the baffle and the sorting openings are used to sort pins of different sizes. Thus, the effect of quickly sorting pins of different sizes can be achieved.
[0009] As a further improvement of the utility model, two pull handles are symmetrically fixed and connected to the two sides of the top frame, and a pull handle is fixed and connected to the side of the baffle away from the inner wall of the top frame. Thus, the top frame can be conveniently picked up, and the baffle can be conveniently pulled out and replaced.
[0010] As a further improvement of the utility model, a middle frame is movably connected to the bottom end of the top frame, pull handles are symmetrically fixed and connected to the two sides of the baffle horizontally, and a plurality of bottom ports are uniformly formed in the bottom end of the middle frame. Thus, the smaller pins among the small pins can be screened.
[0011] As a further improvement of the utility model, a blocking groove is formed in the top end of the side of the middle frame close to the pull handle, the pull handle slides in the blocking groove, and two limiting ports are symmetrically formed in the two sides of the bottom end of the middle frame away from the pull handles. Thus, the top frame and the baffle can be prevented from being blocked when they are put in as a whole.
[0012] As a further improvement of the utility model, a bottom frame is arranged at the bottom end of the middle frame, a limiting groove is formed in the top surface of the bottom frame, the middle frame is slidingly connected in the limiting groove, and two limiting blocks are symmetrically fixed and connected to the top end of the limiting groove. Thus, the middle frame can be fixed.
[0013] As a further improvement of the utility model, the two limiting ports are slidingly connected to the top end of the two limiting blocks, an extension mechanism is fixed and connected to the side of the bottom frame away from the bottom frame, and a transmission mechanism is fixed and connected to the side of the extension mechanism away from the bottom frame. Thus, the extension mechanism can be controlled to extend and retract by electricity, thereby achieving the effect of shaking and screening.
[0014] Compared with the prior art, the utility model has the advantages that:
[0015] 1. The top frame, the baffle and the middle frame are driven by the transmission mechanism to drive the extension mechanism to extend and retract, thereby driving the middle frame to shake and screen. Since the top frame is placed at the top end of the middle frame, and the top frame is divided by the baffle, when mixed pins are put into the top frame from the top end, the pins are shaken and screened by the middle frame and the top frame, thereby achieving the effect of screening the mixed pins by electric extension and retraction. The electric extension and retraction screening device can continuously and quickly complete the screening task without manual operation, thereby greatly improving the screening efficiency. Compared with the traditional manual measurement screening method, the electric extension and retraction screening reduces the error caused by human factors and improves the accuracy of the screening result. Moreover, manual screening may involve heavy lifting and long-term repetitive labor, which may easily cause occupational injuries, while electric extension and retraction screening avoids these problems and improves work safety.
[0016] 2. The baffle, with its adjustable sliding groove, baffle, and pull handle, can be manually pulled along the groove opening by the pull handle, allowing for the replacement of baffles with different openings. This enables the screening of different sized pins by changing the screening opening. By changing the screening opening size, the equipment can effectively screen pins of different sizes, avoiding low screening efficiency caused by an unsuitable opening. Furthermore, a suitable screening opening reduces pin clogging during screening, making the process smoother. When production needs change and different sizes of pins need to be screened, simply changing the screening opening quickly adapts to the new requirements, improving production flexibility.

Detailed Implementation
[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0025] As shown in the figure, a PCB forming pin screening device includes a top frame 101, a limiting sliding groove 103, a baffle 104, a middle frame 201, a blocking groove 204, a bottom frame 301, a telescopic mechanism 304, and a transmission mechanism 305.
[0026] First, based on the required size of the pins to be screened, select a suitable baffle 104 according to the different sizes of screening openings 105 on the surface of different baffles 104. Then, the worker holds and pulls the suitable baffle 104 along the side opening and limiting sliding groove 103 of the top frame 101 and pushes it into the top frame 101, thereby achieving the effect of portable replacement of the screening opening 105. By changing the screening opening 105 of different sizes, it can be ensured that the screening equipment can effectively screen pins of different sizes, avoiding the problem of low screening efficiency caused by unsuitable screening openings 105.
[0027] Furthermore, after the baffle 104 is pushed into the top frame 101 by pulling the handle 106, the worker lifts the top frame 101 and the baffle 104 by pulling the handle 102. Then, the handle 106 is aligned with the anti-blocking groove 204, and the top frame 101 is placed into the middle frame 201. At this time, the handle 106 will slide down along the anti-blocking groove 204, so that the middle frame 201 and the top frame 101 will not be obstructed by the handle 106.
[0028] Furthermore, after the top frame 101 and the middle frame 201 are placed, the two limiting ports 205 at the bottom of the middle frame 201 are aligned with the limiting block 303. The middle frame 201 is then placed into the limiting groove 302 at the top of the bottom frame 301 by manually holding the lifting handle 202. This ensures that the limiting ports 205 and the limiting block 303 are in close contact, and the bottom of the middle frame 201 is perfectly aligned with the limiting groove 302. The mixed pins are then poured into the top of the baffle 104. At this point, the transmission mechanism 305 is activated, driving the telescopic mechanism 304 to extend and retract. Since the other end of the telescopic mechanism 304 is fixed to the bottom frame 301, it causes the bottom frame 301 to reciprocate and vibrate, achieving the effect of screening the mixed pins through electric telescopic movement. The electric telescopic screening equipment can continuously and quickly complete the screening task without manual operation, greatly improving screening efficiency. Compared to traditional manual measurement and sieving methods, electric telescopic sieving reduces errors caused by human factors and improves the accuracy of sieving results.
[0029] Furthermore, the depth of the limiting opening 205 at the bottom of the middle frame 201 is set to be lower than the height of the limiting block 303. When the middle frame 201 is placed at the top of the bottom frame 301, a gap will be created between the bottom of the limiting groove 302 and the bottom of the middle frame 201. Since the bottom opening 203 at the bottom of the middle frame 201 is set to be smaller than the required pins, during vibrating screening, the smaller portion of the pins falling from the top screening opening 105 can be screened into the bottom frame 301. This ensures that the middle frame 201 contains only the required pins. Using two different sized screens ensures that only pins within a specific size range can pass through the middle screening area, thus achieving precise separation. This method is more precise than using a single screen and reduces the possibility of misscreening and missed screening.
[0030] The advantages of this invention are: 1) The electrically telescopic screening device can continuously and quickly complete the screening task without manual operation, greatly improving screening efficiency. 2) It can ensure that the screening device can effectively screen pins of different sizes, avoiding the problem of low screening efficiency caused by unsuitable filter openings. 3) By using two different sized screens, it can ensure that only pins within a specific size range can pass through the middle screening area, thereby achieving precise separation.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
