Abstract
Description
Technical Field
[0001] This utility model relates to the field of SMT pick and place machine technology, and specifically to an error-proof feeding device for SMT pick and place machines. Background Technology
[0002] SMT (Surface Mount Technology) placement machines, also known as "placement machines" or "surface mount systems," are key pieces of equipment in the electronics manufacturing industry. They are used to accurately mount surface mount components onto printed circuit boards (PCBs). Their main function is to move the placement head to accurately place leadless or short-lead surface mount components (such as chips, resistors, and capacitors) onto the PCB pads, thereby improving the placement speed and accuracy of electronic components and enhancing the efficiency and quality of the entire electronics manufacturing process.
[0003] In the existing technology, when SMT placement machines mount components onto substrates, a feeding device is required to feed the substrates. However, most feeding devices are not convenient to adjust and adapt to the length specifications of the substrates, resulting in low flexibility. Furthermore, during the feeding process, the substrates may deviate from their travel trajectory, causing misalignment.
[0004] Therefore, a fault-prevention feeding device for SMT pick and place machines is proposed. Utility Model Content
[0005] The purpose of this utility model is to solve the problems mentioned in the background art above, and to provide an error-proof feeding device for SMT pick and place machines.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] An error-proof feeding device for an SMT pick-and-place machine includes a base plate. The base plate has two mounting plates on its top, a baffle on its top, and two fixing rods on its top. One fixing rod has a hinged shield door that magnetically attaches to the other fixing rod. The two mounting plates have height-adjusting lifting mechanisms, each with an adjustment mechanism for positioning and storing the substrate. The base plate has a worktable on its top, and the two mounting plates have pushing mechanisms for positioning and feeding the substrate. These pushing mechanisms are mounted on the adjustment mechanisms and contact the worktable.
[0008] Furthermore, the lifting mechanism includes a one-way lead screw, which is rotatably installed inside the front mounting plate. A cylinder is installed inside the rear mounting plate. A lifting plate is threaded onto the outer wall of the one-way lead screw and is slidably installed on the outer wall of the cylinder. A motor is installed at the top of the one-way lead screw and is mounted on the surface of the front mounting plate.
[0009] Furthermore, the adjustment mechanism includes two rectangular plates, which are symmetrically installed at the bottom of the lifting plate. A bidirectional lead screw is rotatably installed on the two rectangular plates. Two movable seats are threaded on the outer wall of the bidirectional lead screw and are slidably installed on the lifting plate. A second motor is installed at the front end of the bidirectional lead screw and is installed on the surface of the front rectangular plate. Two partition plates are installed on the top of each of the two movable seats.
[0010] Furthermore, the pushing mechanism includes two mounting brackets, which are mounted on the top of the mounting plate. The width of one end of the mounting bracket is adapted to the gap between the two partition plates, and a fixing shell is installed between the two mounting brackets.
[0011] Furthermore, a one-way lead screw two is rotatably installed inside the fixed shell, and a push rod is threaded on the outer wall of the one-way lead screw two, and the push rod is slidably installed on the inner wall of the fixed shell. A motor three is installed at the left end of the one-way lead screw two, and the motor three is installed on the surface of the fixed shell.
[0012] Furthermore, two T-shaped blocks are slidably installed on the baffle, and a positioning rod is installed on the top of each of the two T-shaped blocks, and the positioning rod is slidably installed on the right partition plate.
[0013] The beneficial effects of this utility model are as follows:
[0014] This invention, through the arrangement of a lifting plate, partition plates, and push rods, allows for the following operation: The shielding door is opened, and then, according to the length specifications of the substrate, motor two is activated, driving a bidirectional lead screw to rotate. This causes two moving seats to move closer together, and the four partition plates move in pairs, with the two positioning rods moving accordingly to match the length specifications of the substrate. Multiple substrates are then placed sequentially on the four partition plates. The shielding door is then closed, and motor three is activated, driving a unidirectional lead screw two to rotate, which in turn moves the push rod laterally to push the substrate. With the cooperation of the two positioning rods, the substrates are positioned and fed, preventing deviation or misalignment in their forward trajectory. After the first substrate is fed, the push rod resets, and motor one is activated, driving a unidirectional lead screw one to rotate, causing the lifting plate to move upward. The four partition plates and substrates move accordingly, revealing the second substrate. This combined operation allows for the sequential positioning and feeding of substrates of various lengths, enabling the sequential positioning and feeding of substrates of various specifications. It avoids deviation or misalignment during the feeding process, is simple to operate, and highly practical. Attached Figure Description

[0026] like Figure 1-2 As shown, the error-proof feeding device for an SMT pick-and-place machine includes a base plate 1, two mounting plates 2 on the top of the base plate 1, a baffle 3 on the top of the base plate 1, and two fixing rods 4 on the top of the base plate 1. A shielding door 5 is hinged to one of the fixing rods 4 and magnetically attracted to the other fixing rod 4. The two mounting plates 2 are equipped with lifting mechanisms 6 for height adjustment, and the lifting mechanisms 6 are equipped with adjustment mechanisms 7 for positioning and storing the substrate. A worktable 8 is located on the top of the base plate 1, and the two mounting plates 2 are equipped with pushing mechanisms 9 for positioning and pushing the substrate. The feeding mechanism 9 is mounted on the adjusting mechanism 7, and the pushing mechanism 9 is in contact with the worktable 8. In this embodiment, during use, the shielding door 5 is opened, and then the length of the substrate is adjusted to match the substrate through the adjusting mechanism 7. The positioning parts of the pushing mechanism 9 move accordingly, placing multiple substrates sequentially on the adjusting mechanism 7. Then the shielding door 5 is closed. At this time, the lifting mechanism 6 and the pushing mechanism 9 work together to sequentially position and feed the substrates one by one, thereby realizing the sequential positioning and feeding of substrates of various lengths and specifications. This avoids deviation and misalignment during the feeding process, and is simple to operate and highly practical.
[0027] like Figure 1-3 As shown, the lifting mechanism 6 includes a one-way screw 601, which is rotatably mounted inside the front mounting plate 2. A cylinder 602 is mounted inside the rear mounting plate 2. A lifting plate 603 is threaded onto the outer wall of the one-way screw 601 and slides on the outer wall of the cylinder 602. A motor 604 is mounted at the top of the one-way screw 601 and is mounted on the surface of the front mounting plate 2. In this embodiment, starting the motor 604 drives the one-way screw 601 to rotate, causing the lifting plate 603 to move longitudinally, thereby adjusting the height of the lifting plate 603.
[0028] like Figure 1-3As shown, the adjustment mechanism 7 includes two rectangular plates 701, which are symmetrically mounted on the bottom of the lifting plate 603. A bidirectional lead screw 702 is rotatably mounted on the two rectangular plates 701. Two movable seats 703 are threaded onto the outer wall of the bidirectional lead screw 702, and the movable seats 703 are slidably mounted on the lifting plate 603. A second motor 704 is mounted at the front end of the bidirectional lead screw 702, and the second motor 704 is mounted on the surface of the front rectangular plate 701. Two partition plates 705 are mounted on the top of each of the two movable seats 703. In this embodiment, starting the second motor 704 drives the bidirectional lead screw 702 to rotate, causing the two movable seats 703 to move closer to each other, and the four partition plates 705 to move closer to each other in pairs, which can accommodate the positioning and storage of substrates of various lengths.
[0029] like Figure 1-2 As shown, the pushing mechanism 9 includes two mounting brackets 901. The mounting brackets 901 are mounted on the top of the mounting plate 2. The width of one end of the mounting bracket 901 is adapted to the gap between the two partition plates 705. A fixing shell 902 is installed between the two mounting brackets 901. In this embodiment, the setting of the two mounting brackets 901 will affect the upward movement of the four partition plates 705, and the two mounting brackets 901 provide stable support for the fixing shell 902.
[0030] like Figure 5 As shown, a one-way lead screw 903 is rotatably mounted inside the fixed housing 902. A push rod 904 is threaded onto the outer wall of the one-way lead screw 903 and is slidably mounted on the inner wall of the fixed housing 902. A motor 905 is mounted on the left end of the one-way lead screw 903 and is mounted on the surface of the fixed housing 902. In this embodiment, starting the motor 905 drives the one-way lead screw 903 to rotate, which in turn drives the push rod 904 to move laterally and push the substrate.
[0031] like Figure 3-4 As shown, two T-shaped blocks 906 are slidably mounted on the baffle 3. Each of the two T-shaped blocks 906 has a positioning rod 907 mounted on its top. The positioning rod 907 is slidably mounted on the right partition plate 705. In this embodiment, when the four partition plates 705 move closer to each other in pairs, the two positioning rods 907 move accordingly to position the substrate during the pushing process and prevent displacement. The positioning rods 907 are slidably set between themselves and the right partition plate 705 so that the height of the two positioning rods 907 does not change.
[0032] In summary, during use, by opening the shielding door 5, and then adjusting the substrate according to its length specifications using the adjusting mechanism 7, the positioning parts of the pushing mechanism 9 move accordingly, placing multiple substrates sequentially on the adjusting mechanism 7. Then, the shielding door 5 is closed. At this point, with the cooperation of the lifting mechanism 6 and the pushing mechanism 9, the substrates are individually positioned and fed, thus achieving sequential positioning and feeding of substrates of various lengths. This avoids deviation and misalignment during feeding, is simple to operate, and highly practical. Starting motor 604 drives the unidirectional lead screw 601 to rotate, causing the lifting plate 603 to move longitudinally, thereby adjusting the height of the lifting plate 603. Starting motor 704 drives the bidirectional lead screw 702 to rotate. The two movable seats 703 move closer to each other, and the four partition plates 705 move closer to each other in pairs. This allows for the positioning and storage of substrates of various lengths. The two mounting brackets 901 affect the upward movement of the four partition plates 705, and the two mounting brackets 901 provide stable support for the fixed shell 902. The motor 905 is started, which drives the one-way lead screw 903 to rotate, causing the push rod 904 to move laterally and push the substrate. When the four partition plates 705 move closer to each other in pairs, the two positioning rods 907 move accordingly to position the substrate during the pushing process and prevent displacement. The positioning rods 907 are slidably set between themselves and the right partition plate 705 so that the height of the two positioning rods 907 does not change.
