Description

Technical Field

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

[0002] Circuit boards purchased from upstream manufacturers are shipped in stacked packages. When assembling these circuit boards with various electronic components, each board needs to be processed individually. Automated assembly places the circuit boards in layers in a hopper, facilitating the subsequent retrieval of one or more boards as needed. However, traditional board loading mechanisms require manual intervention to periodically check whether the circuit boards at the loading position have been completely transferred into the hopper, leading to inconvenience.

[0003] Therefore, it is necessary to provide a circuit board mounting device. Utility Model Content

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a circuit board mounting device, including a frame 1, and further including a hopper mechanism 2, a feeding mechanism 3, a transfer mechanism 4, and a weighing mechanism 5 disposed on the frame 1. The transfer mechanism 4 is used to transfer the product in the weighing mechanism 5 to the feeding mechanism 3, and the feeding mechanism 3 is used to transport the product to the hopper mechanism 2. The weighing mechanism 5 includes a first frame 51 disposed on the frame 1, a guide rod 52 disposed on the first frame 51, a lifting plate 53 slidably disposed on the guide rod 52, a weighing sensor 54 disposed on the lifting plate 53, a lead screw 55 disposed on the frame 1 for driving the lifting plate 53 to rise and fall, a material support frame 56 disposed at the sensing end of the weighing sensor 54, and a stop block 57 disposed on the first frame 51 for limiting the four sides of the material support frame 56. The first frame 51 is provided with a clearance hole for avoiding the material support frame 56.

[0022] It should be noted that this application uses a PLC control system to control the weighing mechanism 5, the transfer mechanism 4, the sheet feeding mechanism 3, and the hopper mechanism 2. This application also includes an audible and visual alarm controlled by the PLC control system.

[0023] In actual use, the stacked products are manually placed on the pallet 56 of the weighing mechanism 5, and positioned by the stop block 57. Then, the lead screw 55 drives the lifting plate 53 to rise and fall, causing the lifting plate 53 to synchronously raise and lower the weighing sensor 54 and the pallet 56 until the transfer mechanism 4 can transfer the products in the pallet 56. The transfer mechanism 4 transfers one product at a time, and the lead screw 55 drives the lifting plate 53 to fall one unit height. The transfer mechanism 4 transfers the products to the sheet feeding mechanism 3, where the products are conveyed to the hopper mechanism 2. During the transfer of products in the pallet 56, the weighing sensor 54 monitors the weight of the pallet 56 to determine the quantity of products in the pallet 56. When the weighing sensor 54 displays only the weight of the pallet 56, it indicates that all products in the pallet 56 have been transferred. The PLC control system controls the audible and visual alarm to issue a signal, and then the pallet 56 is manually reloaded.

[0024] In the above design, by setting a weighing sensor 54 to monitor the weight of the products in the material rack 56, the quantity of products in the material rack 56 can be automatically determined, and the manual reminder can be made to put materials into the material rack 56 automatically.

[0025] Specifically: such as Figure 1 and Figure 3 As shown, the hopper mechanism 2 also includes a feeding hopper 21, a first linear module 22 arranged on the frame 1 along the Y-axis, a second linear module 23 arranged at the output end of the first linear module 22 along the Z-axis, a support frame 24 arranged at the output end of the second linear module 23 for supporting the feeding hopper 21, and a side pressure member 25 arranged on one side of the support frame 24 for fixing the feeding hopper 21. The feeding hopper 21 is provided with several feeding areas arranged along the Y-axis, and each feeding area is provided with several feeding layers arranged along the Z-axis.

[0026] In actual use, the first linear module 22 drives the second linear module 23 to move along the Y-axis, and the second linear module 23 drives the tray frame 24 to rise and fall along the Z-axis, so that the film loading tray 21 corresponds with the film feeding mechanism 3 and can receive products. The side pressure member 25 fixes the film loading tray 21 in the tray frame 24 to prevent the film loading layer from shaking when receiving films.

[0027] In the above design, the structural design and specific implementation of the hopper mechanism 2 can realize the automatic movement of the feeding hopper 21, and realize the receiving of different feeding areas and different feeding layers of the feeding hopper 21.

[0028] Specifically: such as Figure 3As shown, the pallet frame 24 includes a base plate 241, a front side plate 242 disposed on the front side of the base plate 241 and connected to the output end of the second linear module 23, a rear side plate 243 disposed on the rear side of the base plate 241, and a right side plate 244 disposed on the right side of the base plate 241. The side pressure member 25 includes a first cylinder 251 disposed on the rear side plate 243 and a pressure plate 252 disposed on the output end of the first cylinder 251.

[0029] In actual use, the film loading chamber 21 is placed on the base plate 241. The pressure plate 252 is driven by the first cylinder 251 to squeeze one side of the film loading chamber 21, so that the two sides of the film loading chamber 21 are fixed by the pressure plate 252 and the front side plate 242 respectively.

[0030] In the above design, the structural design and specific implementation of the tray frame 24 and the side pressure member 25 enable the placement and fixing of the film loading tray 21.

[0031] Specifically: such as Figure 4 As shown, the feeding mechanism 3 includes a second seat 31 mounted on the frame 1, a driving pulley and a driven pulley 34 mounted at both ends of the second seat 31, a motor mounted on the second seat 31 for driving the driving pulley to rotate, and a synchronous belt 32 that drives the driving pulley and the transmission pulley. The upper parallel section of the synchronous belt 32 is used for conveying the product, and the second seat 31 forms a limiting part for limiting the two sides of the upper parallel section of the synchronous belt 32.

[0032] In actual use, the end face of the upper parallel section of the synchronous belt 32 is aligned with the feeding layer of the feeding bin 21 that needs to receive the material. The driving pulley is rotated by the motor, and with the cooperation of the driven pulley 34, the synchronous belt 32 is driven to transport the product to the feeding bin 21.

[0033] In the above design, the structural design and specific implementation of the feeding mechanism 3 can effectively realize the delivery of products.

[0034] Specifically: such as Figure 5 As shown, the transfer mechanism 4 includes a No. 3 seat 41 mounted on the frame 1, a No. 3 linear guide rail 42 mounted on the No. 3 seat 41 along the Y-axis, a sliding plate 43 slidably mounted on the No. 3 linear guide rail 42, a No. 3 cylinder 44 mounted on the No. 3 seat 41 for driving the sliding plate 43 to slide along the No. 3 linear guide rail 42, a No. 4 cylinder 45 vertically mounted on the sliding plate 43, a connecting frame mounted on the output end of the No. 4 cylinder 45, and several suction cups 46 mounted on the connecting frame.

[0035] In actual use, cylinder 44 drives the sliding plate 43 to reciprocate along linear guide rail 42 between the weighing mechanism 5 and the feeding mechanism 3. Cylinder 45 drives the connecting frame to lift and lower, enabling the suction cup 46 to pick up and drop materials. When a product needs to be transferred from the support frame 56 to the feeding mechanism 3: cylinder 44 drives the sliding plate 43 to move so that the suction cup 46 is above the support frame 56. Then, cylinder 45 drives the connecting frame to move down so that the suction cup 46 picks up the product at the top of the support frame 56. Then, cylinder 45 resets. Then, cylinder 44 drives the sliding plate 43 to move so that the suction cup 46 is above the feeding mechanism 3. Then, cylinder 45 drives the connecting frame to move down so that the suction cup 46 places the picked-up product on the feeding mechanism 3. Finally, cylinder 45 drives the connecting frame to reset.

[0036] In the above design, the structural design and specific implementation of the transfer mechanism 4 enable automatic transfer of products.

[0037] Specifically: such as Figure 4 As shown, the feeding mechanism 3 also includes a roller pressing assembly 33, which includes a mounting block 331 on the second seat 31, a first rod 332 on the mounting block 331, a bearing 333 whose inner ring is connected to the first rod 332, and a bushing 334 on the first rod 332 for limiting the bearing 333 on both sides.

[0038] In actual use, when the product is transported on the synchronous belt 32, the upper surface of the product is rolled by the bearing 333.

[0039] In the above design, the structural design and specific implementation of the roller pressing assembly 33 enable the products conveyed by the feeding mechanism 3 to be roller pressed, preventing the products in the feeding mechanism 3 from tilting and falling off the conveying track.

[0040] Specifically, each of the stop blocks 57 has a chamfered corner on the side of its upper end opposite to the material support frame 56.

[0041] In the above design, the chamfered angle helps to place the product on the tray 56.

[0042] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
