Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and in particular relates to a bare circuit board boarding machine. Background Art

[0002] In the electronics manufacturing industry, circuit boards are the basic components of various electronic devices. Among them, circuit boards without any electronic components are called "bare boards". The transportation, storage and loading of bare boards (i.e. moving bare boards from storage locations to designated locations on the production line) are crucial links in the production process.

[0003] Traditionally, bare board loading operations are mostly performed using circuit board turnover boxes. Multiple card slots are longitudinally arranged inside the turnover box, and bare boards are manually inserted into these card slots one by one. When it is necessary to transfer the bare board from the turnover box to the production line, the turnover box uses a lifting mechanism to raise the circuit board to the same height as the transmission track on the production line, so that the circuit board can slide out of the card slot of the turnover box and fall into the transmission track, thus completing the board loading operation. However, this process of manually inserting bare boards into the turnover box is not only cumbersome, but also inefficient, and it is difficult to meet the modern electronic manufacturing industry's high-efficiency and high-automation production needs.

[0004] Therefore, there is an urgent need for a high-efficiency, high-automatic bare board mounting machine for circuit boards. Utility Model Content

[0005] The utility model aims to provide a bare circuit board loading machine to address the deficiencies in the prior art, which can directly take out and load bare circuit boards from stacked bare circuit boards without manual intervention, thereby improving production efficiency and automation level.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] The avoidance mechanism is connected to the first track and the second track in a transmission manner, and is used to make the first track and the second track avoid the circuit board when the adsorption mechanism rises after adsorbing the circuit board.

[0014] Furthermore, a slot plate is fixed on the first rail and the second rail, and an active arm and a driven arm are provided on the linkage rod. The active arm is connected to the avoidance cylinder, and the driven arm is connected to the slide groove of the slot plate. When the active arm causes the linkage rod to rotate, the driven arm slides in the slide groove and causes the first rail and the second rail to swing inward and outward.

[0015] Furthermore, the first support plate is fixedly arranged, and the second support plate is movably arranged. A translation screw is connected between the first support plate and the second support plate. When the translation screw rotates, the second support plate approaches or moves away from the first support plate.

[0019] Furthermore, the adsorption mechanism includes 4 vacuum suction cups.

[0020] Furthermore, a limiting cylinder for limiting the lifting height of the adsorption mechanism is provided between the first lifting mechanism and the adsorption mechanism.

[0033] See attached Figure 1 To Attachment Figure 5 , the figure shows a specific embodiment of a bare board mounting machine for a circuit board provided by the utility model.

[0034] See attached Figure 1 , the bare board machine for circuit boards includes:

[0035] A board storage platform 1, which is used for stacking circuit boards;

[0036] A suction mechanism 2 is arranged above the board storage platform 1, and a first lifting mechanism 3 is connected to the suction mechanism 2. The first lifting mechanism 3 is used to drive the suction mechanism 2 to move vertically up and down. The suction mechanism 2 is used to suction the circuit board from the board storage platform 1;

[0037] A transmission mechanism 4 is provided between the board storage platform 1 and the adsorption mechanism 2, and the transmission mechanism 4 includes a first track 410 and a second track 420 that are movably arranged to transmit the circuit board;

[0038] The avoidance mechanism 5 is transmission-connected to the first rail 410 and the second rail 420 , and is used to make the first rail 410 and the second rail 420 avoid the circuit board when the adsorption mechanism 2 is lifted up after adsorbing the circuit board.

[0039] See attached Figure 2 In the above embodiment, from top to bottom, they are the first lifting mechanism 3, the adsorption mechanism 2, the transmission mechanism 4, and the board storage platform 1. Before use, the bare circuit boards are stacked and placed on the board storage platform 1, without the need to manually insert them into the turnover box one by one, which is convenient and quick. When in use, the first lifting mechanism 3 drives the adsorption mechanism 2 to descend below the transmission mechanism 4, and directly adsorbs a circuit board from the stacked circuit boards; then, the first lifting mechanism 3 drives the adsorption mechanism 2 to rise, and the avoidance mechanism 5 drives the first track 410 and the second track 420 to avoid the circuit board, so that the circuit board can rise smoothly and avoid collision with the transmission mechanism 4; when it rises above the transmission mechanism 4, the avoidance mechanism 5 drives the first track 410 and the second track 420 to reset; the adsorption mechanism 2 cancels the adsorption state, and the circuit board falls onto the transmission mechanism 4, that is, it is erected between the first track 410 and the second track 420, and then is sent out by the transmission mechanism 4 to complete the board loading. In the embodiment, the first lifting mechanism 3 is a cylinder.

[0040] See attached Figure 4 In the above embodiment, the transmission mechanism 4 further includes a first support plate 430 and a second support plate 440, the first track 410 is vertically arranged on the first support plate 430, the second track 420 is vertically arranged on the second support plate 440, and the avoidance mechanism 5 is used to drive the first track 410 and the second track 420 to swing outward. In the embodiment, the first support plate 430 and the second support plate 440 are installed on the machine table 10 of the board loading machine, the first track 410 is vertically arranged on the first support plate 430 and can be turned outward, and the second track 420 is vertically arranged on the second support plate 440 and can be turned outward. In the process that the adsorption mechanism 2 adsorbs the circuit board and rises, the avoidance mechanism 5 drives the first track 410 and the second track 420 to swing outward to avoid the circuit board. After the circuit board rises to the right position, the first track 410 and the second track 420 are driven to reset inward to the vertical state, so as to facilitate the carrying and transportation of the circuit board.

[0041] See attached Figure 5In the above embodiment, the avoidance mechanism 5 includes a linkage rod 510 connecting the first track 410 and the second track 420, and a avoidance cylinder 520 connected to the linkage rod 510. The avoidance cylinder 520 drives the linkage rod 510 to make the first track 410 and the second track 420 move synchronously. A slot plate 530 is fixed on both the first track 410 and the second track 420. The linkage rod 510 is provided with an active arm 540 and a passive arm 550. The active arm 540 is connected to the avoidance cylinder 520, and the passive arm 550 is connected to the slide groove 531 of the slot plate 530. When the active arm 540 rotates the linkage rod 510, the passive arm 550 slides in the slide groove 531 and makes the first track 410 and the second track 420 swing inside and outside. In the embodiment, when the avoidance cylinder 520 is pushed forward, the active arm 540 moves forward, and the end of the active arm 540 connected to the linkage rod 510 rotates, the linkage rod 510 rotates synchronously, and the two passive arms 550 rotate synchronously. For the first track 410, the end of the driven arm 550 slides in the slide groove 531 of the slot plate 530. Since the slot plate 530 is fixed on the first track 410, the driven arm 550 drives the slot plate 530 to move and causes the first track 410 to swing outward. For the second track 420, its structure is symmetrical with the first track 410, and the second track 420 also swings outward. When the avoidance cylinder 520 retracts, the first track 410 and the second track 420 swing inward to return to a vertical state through the transmission of the active arm 540, the linkage rod 510, the driven arm 550 and the slot plate 530.

[0042] See attached Figure 4 In the above embodiment, the first support plate 430 is fixedly arranged, the second support plate 440 is movably arranged, and a translation screw 6 is connected between the first support plate 430 and the second support plate 440. When the translation screw 6 rotates, the second support plate 440 approaches or moves away from the first support plate 430. In the embodiment, the first support plate 430 is fixed on the machine table 10, and the second support plate 440 is movably arranged on the machine table 10. The translation screw 6 drives the second support plate 440 to approach or move away from the first support plate 430, and the width between the first track 410 installed on the first support plate 430 and the second track 420 installed on the second support plate 440 is adjustable to adapt to circuit boards of different sizes, thereby improving the versatility of the device.

[0043] See attached Figure 3In the above embodiment, the first lifting mechanism 3 is further provided with a translation guide rail 7 parallel to the translation screw rod 6, and the first lifting mechanism 3 is movably connected to the translation guide rail 7. In the embodiment, the translation guide rail 7 is used to drive the first lifting mechanism 3 and the adsorption mechanism 2 to move as a whole, so as to adjust the adsorption position of the adsorption mechanism 2 synchronously after adjusting the width between the first track 410 and the second track 420, or to fine-tune the position of the adsorption mechanism 2 during the process of rising, falling, and placing the board to ensure accurate placement on the first track 410 and the second track 420.

[0044] See attached Figure 2 In the above embodiment, a second lifting mechanism 8 is further included. The second lifting mechanism 8 is arranged below the transmission mechanism 4. The plate storage platform 1 can be lifted and lowered on the second lifting mechanism 8. The second lifting mechanism 8 includes a motor 810 and a plurality of lifting screws 820 connected to the motor 810. The plate storage platform 1 is installed on the lifting screws 820. When the lifting screws 820 rotate under the drive of the motor 810, the plate storage platform 1 moves up and down. In the embodiment, there are three lifting screws 820 connected to the corners of the plate storage platform 1. The motor 810 is installed below the plate storage platform 1. The motor 810 is connected to the four lifting screws 820 through chains and sprockets, so as to drive the plate storage platform 1 to move up and down by rotating the four lifting screws 820 at the same time. During use, as the adsorption mechanism 2 takes away the circuit board, the plate storage platform 1 also slowly rises and approaches the transmission mechanism 4. Therefore, the distance required for the first lifting mechanism 3 to be extended and retracted is always consistent, thereby improving the operation efficiency of the equipment.

[0045] See attached Figure 3 In the above embodiment, the adsorption mechanism 2 includes four vacuum suction cups 210. In the embodiment, the four vacuum suction cups 210 are convenient for adsorption from the four corners of the circuit board, so that the adsorption mechanism 2 can firmly adsorb the circuit board to prevent it from falling off or sliding during the transmission process, thereby ensuring the safety and accuracy of the board loading operation.

[0046] See attached Figure 3In the above embodiment, a limit cylinder 9 for limiting the lifting height of the adsorption mechanism 2 is provided between the first lifting mechanism 3 and the adsorption mechanism 2. In the embodiment, on the one hand, the lifting height of the adsorption mechanism 2 is limited by the limit cylinder 9 to prevent excessive lifting and lowering from causing collision or damage with other parts of the equipment, thereby improving the safety and service life of the equipment. On the other hand, when the bare board mounting machine for circuit boards is connected to the production line, if there are other circuit boards with electronic components already mounted in the production line, and the circuit board needs to temporarily pass through the transmission mechanism 4 of the bare board mounting machine, the limit cylinder 9 can release the limit on the lifting height of the adsorption mechanism 2, so that the adsorption mechanism 2 can be further raised to avoid the circuit boards with electronic components already mounted, ensuring that the circuit boards with electronic components already mounted can pass smoothly through the transmission mechanism 4 of the bare board mounting machine, thereby improving the use scenario of the equipment.

[0047] In summary, the present embodiment provides a bare board loading machine for circuit boards, in which the circuit boards are stacked and placed on a board storage table 1, and the adsorption mechanism 2 is driven by the first lifting mechanism 3 to lift and move longitudinally to adsorb the circuit boards, thereby realizing direct board retrieval from the stacked circuit boards without manual intervention, thereby improving production efficiency; the first track 410 and the second track 420 are made to avoid the circuit boards by the avoidance mechanism 5, thereby facilitating the smooth ascent of the circuit boards after adsorption by the adsorption mechanism 2, thereby avoiding collision with the transmission mechanism 4, thereby ensuring safe transmission of the circuit boards; the second support plate 440 is driven to approach or move away from the first support plate 430 by the translation screw 6, thereby making the width of the transmission mechanism 4 adjustable to adapt to circuit boards of different sizes, thereby improving the versatility of the equipment; the second lifting mechanism 8 is provided to make the height of the board storage table 1 adjustable, thereby facilitating matching with the height of the adsorption mechanism 2 and the transmission mechanism 4, thereby improving the flexibility and convenience of the loading operation; the present embodiment can realize direct board retrieval and loading from the stacked bare boards of circuit boards without manual intervention, thereby improving production efficiency and automation level.
