Description

Technical Field

[0001] This utility model relates to the field of circuit board mounting technology, specifically to a circuit board mounting device. Background Technology

[0002] A pick-and-place machine is a mechanical device that automatically and precisely mounts regularly shaped electronic components onto circuit boards. With the rapid development of industry, my country's electronics industry has also experienced rapid growth, leading to a surge in demand for pick-and-place machines. Currently, most companies use single-head pick-and-place machines for production.

[0003] Application CN202320764080.2 discloses a circuit board mounting device, including a body and a collection mechanism. This device effectively collects circuit boards by using the collection mechanism, reducing the likelihood of components being knocked off by impacts between the circuit board and the square box, thus increasing usability and facilitating use. However, in practical applications, although a sliding plate reduces the impact of the circuit board sliding down, the drop height is still relatively high, leading to frequent breakage incidents. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A circuit board placement device includes a placement mechanism and a receiving mechanism. The placement mechanism includes a placement machine, a chassis mounted at one end of the placement machine, and a receiving box attached to the top of the chassis. The receiving mechanism includes two sliders located on the front and rear sides of the receiving box and attached to the top of the chassis, a hydraulic cylinder fixed to the inner side of the sliders, a support rod connected to the movable end of the hydraulic cylinder, a belt conveyor connected between the two support rods, and multiple cross plates connected to the outer wall of the belt conveyor. A drive assembly is provided on the top of the chassis.

[0007] By adopting the above technical solution, after the shaped circuit board processed by the chip mounter slides into the receiving box, the horizontal plate driven by the belt conveyor accurately receives the circuit board. During the continuous operation of the belt conveyor, the horizontal plate carries the circuit board and smoothly descends to the bottom of the inner cavity of the receiving box. When it reaches the preset height, the horizontal plate performs a tilting action to allow the circuit board to slide into the stacking area of ​​the box without damage, effectively improving the yield of the circuit board.

[0008] In a preferred embodiment, the present invention can be further configured such that: the drive assembly includes a threaded rod rotatably mounted on the top of the chassis, a motor connected between the chassis and the threaded rod, and a slider near the front of the chassis screwed onto the threaded rod.

[0009] In a preferred embodiment, the present invention can be further configured such that: a guide rod is fixedly connected to the top of the chassis, and a slider near the rear side of the chassis is slidably sleeved on the outside of the guide rod.

[0010] In a preferred embodiment, this utility model can be further configured as follows: two hydraulic cylinders are connected in series, and both the hydraulic cylinders and the motor are electrically connected to an external PLC.

[0011] In a preferred embodiment, the present invention can be further configured such that the belt conveyor is inclined and the bottom end of the belt conveyor extends movably to the bottom of the inner cavity of the receiving box.

[0012] In a preferred embodiment, the present invention can be further configured as follows: multiple horizontal plates are spaced at equal intervals and arranged along the conveyor belt of a belt conveyor, wherein the horizontal plates are made of rubber material.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, after the molded circuit board processed by the chip mounter slides into the receiving box, the horizontal plate driven by the belt conveyor accurately receives the circuit board. During the continuous operation of the belt conveyor, the horizontal plate carries the circuit board and smoothly descends to the bottom of the inner cavity of the receiving box. When it reaches the preset height, the horizontal plate performs a tilting action to allow the circuit board to slide into the stacking area of ​​the box without damage, effectively improving the yield of the circuit board.

[0015] 2. In this utility model, the movable ends of the two sets of hydraulic cylinders adjust the bearing reference surface of the receiving box in real time through a coordinated lifting mechanism to ensure that the stacked circuit boards do not interfere with the normal operation trajectory of the belt conveyor. The synchronously operating PLC control system precisely controls the motor operation, drives the threaded rod to drive the slider to perform lateral displacement. This linkage mechanism causes the belt conveyor to generate horizontal displacement as a whole, thereby guiding the horizontal plate to achieve spatial matrix positioning inside the receiving box. Through this dynamic compensation system, the formed circuit boards can be orderly distributed according to the real-time stacking state of the receiving box, effectively improving the utilization rate of the internal space of the receiving box.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of a circuit board mounting device provided by this utility model.

[0028] Example 1:

[0029] Combination Figure 1-4 As shown, the present invention provides a circuit board mounting device, including a mounting mechanism 100 and a receiving mechanism 200. The mounting mechanism 100 includes a mounting machine 110, a chassis 120 mounted at one end of the mounting machine 110, and a receiving box 130 attached to the top of the chassis 120.

[0030] The receiving mechanism 200 includes two sliders 210 located on the front and rear sides of the receiving box 130 and attached to the top of the chassis 120, a hydraulic cylinder 220 fixed to the inner side of the sliders 210, a support rod 230 connected to the movable end of the hydraulic cylinder 220, a belt conveyor 240 connected between the two support rods 230, and a plurality of horizontal plates 250 connected to the outer wall of the belt conveyor 240. The top of the chassis 120 is provided with a drive assembly 300.

[0031] Furthermore, the drive assembly 300 includes a threaded rod 310 rotatably mounted on the top of the chassis 120, a motor 320 connected between the chassis 120 and the threaded rod 310, and a slider 210 near the front of the chassis 120 screwed to the threaded rod 310. The motor 320 cooperates with the threaded rod 310 to make the slider 210 move back and forth along the chassis 120, ensuring that the circuit board can be laid flat inside the receiving box 130.

[0032] Furthermore, the belt conveyor 240 is inclined, and the bottom end of the belt conveyor 240 extends movably to the bottom of the inner cavity of the receiving box 130. The layout design of the belt conveyor 240 ensures that the circuit board will not fall outside the receiving box 130.

[0033] Furthermore, multiple horizontal plates 250 are equally spaced and arranged along the conveyor belt of the belt conveyor 240. The horizontal plates 250 are made of rubber material. When the horizontal plates 250 made of rubber material receive the circuit board, no noise will be produced, and damage to the circuit board can also be reduced.

[0034] Example 2:

[0035] Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, a guide rod 400 is fixedly connected to the top of the chassis 120, and a slider 210 near the rear side of the chassis 120 is slidably sleeved on the outside of the guide rod 400. The guide rod 400 can guide the slider 210 to move horizontally, making the slider 210 move more smoothly.

[0036] Example 3:

[0037] Combination Figure 1-4 As shown, in the above embodiment, two hydraulic cylinders 220 are connected in series. Both the hydraulic cylinders 220 and the motor 320 are electrically connected to an external PLC. Using an external PLC to control the hydraulic cylinders 220 and the motor 320 can improve the ease of use of this device.

[0038] The working principle and usage process of this utility model are as follows: After the molded circuit board processed by the pick-and-place machine 110 slides into the receiving box 130, the horizontal plate 250 driven by the belt conveyor 240 precisely receives the circuit board. During the continuous operation of the belt conveyor 240, the horizontal plate 250 carrying the circuit board smoothly descends to the bottom of the inner cavity of the receiving box 130. When it reaches the preset height, the horizontal plate 250 performs a tilting action, allowing the circuit board to slide into the stacking area of ​​the box without damage. During this process, the moving ends of the two sets of hydraulic cylinders 220 adjust the bearing reference surface of the receiving box 130 in real time through a coordinated lifting mechanism, ensuring that the stacked circuit board does not interfere with the normal operating trajectory of the belt conveyor 240. The synchronously operating PLC control system precisely controls the operation of the motor 320, driving the threaded rod 310 to drive the slider 210 to perform lateral displacement. This linkage mechanism causes the belt conveyor 240 to generate horizontal displacement as a whole, thereby guiding the horizontal plate 250 to achieve spatial matrix positioning inside the receiving box 130. Through this dynamic compensation system, the molded circuit boards can be distributed in an orderly manner according to the real-time stacking state of the receiving box 130, effectively improving the utilization rate of the internal space of the receiving box.
