Description

Technical Field

[0001] This utility model belongs to the field of circuit board assembly technology, and in particular relates to a pusher for circuit board assembly. Background Technology

[0002] With the rapid development of electronic technology, the integration of circuit boards is constantly improving, and their assembly process is becoming increasingly complex and sophisticated. In the process of assembling circuit boards, accurately placing various electronic components in designated positions is a key step to ensure the normal operation and stable performance of the circuit board. As an important device for transferring components, the performance of the pusher directly affects the efficiency and quality of circuit board assembly.

[0003] Traditional pusher structures typically employ solid pusher blocks. However, these blocks lack flexibility and adaptability when dealing with increasingly diverse electronic components. Due to the integrity of their overall structure, they cannot effectively avoid the bent parts of bent components during the pushing process. When the pusher pushes such components, interference is very likely to occur. This not only hinders the normal transfer of components, causing assembly process interruptions and reducing production efficiency, but may also damage components due to forced pushing, increasing production costs.

[0004] To address these issues, we provide a pusher for circuit board assembly. Utility Model Content

[0005] The purpose of this invention is to provide a pusher for circuit board assembly. By combining the positioning block and the pusher plate, it solves the problem that the existing pusher uses a solid pusher block structure, which lacks flexibility and adaptability, and cannot effectively avoid the bent parts of bending components during the pusher process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a pusher for assembling circuit boards, comprising a base plate, a mounting base fixedly connected to the top of the base plate, a telescopic plate provided in the inner cavity of the mounting base, a housing fixedly connected to one side of the telescopic plate, a screw movably connected to the bottom of the inner cavity of the housing via a bearing, a threaded sleeve threadedly connected to the surface of the screw, a movable block fixedly connected to the surface of the threaded sleeve, mounting blocks fixedly connected to both sides of the front end of the movable block, the side of the mounting block away from the movable block penetrating the inner cavity of the housing and extending to the outside of the housing, a connecting plate fixedly connected to the surface of the mounting block, a positioning block fixedly connected to the surface of the connecting plate, a connecting rod fixedly connected to one side of the bottom of the positioning block, and a pusher plate fixedly connected to the bottom of the connecting rod.

[0008] The present invention is further configured such that a mounting plate is fixedly connected to the rear side of the telescopic plate, and mounting holes are provided at the four corners of the surface of the mounting plate.

[0009] The present invention is further configured such that sliding grooves are provided on both sides of the surface of the housing, and one side of the mounting block extends to the outside of the housing through the sliding groove, and the surface of the mounting block and the sliding groove are slidably connected.

[0010] The present invention is further configured such that sliding rods are fixedly connected to both sides of the bottom of the inner cavity of the housing, and sliding holes for cooperating with the sliding rods are opened on both sides of the top of the moving block.

[0011] The present invention is further configured such that the top of the screw penetrates the inner cavity of the housing and extends to the outside of the housing, and the screw has a countersunk hexagonal structure.

[0012] The present invention is further provided that positioning holes are provided on both sides of the top front end of the base plate, and the positioning holes are symmetrically arranged.

[0013] The present invention is further configured such that fasteners are threadedly connected to the surface of the positioning block, and the positioning block is threadedly connected to the connecting plate through the fasteners.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0026] Please see Figure 1-5 This utility model is a pusher for assembling circuit boards, including a base plate 1, a mounting base 2 fixedly connected to the top of the base plate 1, a telescopic plate 3 provided in the inner cavity of the mounting base 2, a housing 4 fixedly connected to one side of the telescopic plate 3, a screw 5 movably connected to the bottom of the inner cavity of the housing 4 through a bearing, a threaded sleeve 6 threadedly connected to the surface of the screw 5, a moving block 7 fixedly connected to the surface of the threaded sleeve 6, mounting blocks 8 fixedly connected to both sides of the front end of the moving block 7, the side of the mounting block 8 away from the moving block 7 penetrating the inner cavity of the housing 4 and extending to the outside of the housing 4, a connecting plate 9 fixedly connected to the surface of the mounting block 8, a positioning block 10 fixedly connected to the surface of the connecting plate 9, a connecting rod 11 fixedly connected to one side of the bottom of the positioning block 10, and a pusher plate 12 fixedly connected to the bottom of the connecting rod 11.

[0027] Specifically: The base plate 1 and mounting base 2 serve as safety protection, ensuring that the internal pusher is not interfered with by the external environment, thus improving the stability of the equipment during operation. The screw 5 and the threaded sleeve 6 are connected by threads, which drives the moving block 7 to rise and fall. The height of the positioning block 10 can be adjusted according to the usage requirements, thereby adjusting the pushing height of the pusher plate 12 to meet the installation requirements of components of different sizes, while achieving a flexible debugging effect. Example 2

[0028] Please see Figure 1-5 Based on Embodiment 1, a mounting plate 13 is fixedly connected to the rear side of the telescopic plate 3. Mounting holes 14 are provided at the four corners of the surface of the mounting plate 13. Slide grooves 15 are provided on both sides of the surface of the housing 4. One side of the mounting block 8 extends to the outside of the housing 4 through the slide groove 15. The surface of the mounting block 8 and the slide groove 15 are slidably connected. Slide rods 16 are fixedly connected to both sides of the bottom of the inner cavity of the housing 4. Slide holes 17 that cooperate with slide rods 16 are provided on both sides of the top of the moving block 7. The top of the screw 5 penetrates the inner cavity of the housing 4 and extends to the outside of the housing 4. The screw 5 has a countersunk hexagonal structure. Positioning holes 18 are provided on both sides of the top front end of the bottom plate 1. The positioning holes 18 are symmetrically arranged. Fasteners 19 are threadedly connected to the surface of the positioning block 10. The positioning block 10 is threadedly connected to the connecting plate 9 through the fasteners 19. A washer 20 is provided on one side of the fastener 19. The washer 20 is made of stainless steel.

[0029] Specifically: Mounting plate 13 and mounting hole 14 are used to connect external telescopic cylinders to ensure the stability of the installation of telescopic cylinders and telescopic plate 3. The telescopic cylinder drives the telescopic plate 3 to move, achieving the purpose of rapid material pushing. The inner cavity of the slide groove 15 is slidably connected to the surface of the mounting block 8, ensuring the installation stability of its external connection structure while improving the limiting effect. The slide rod 16 slides in the inner cavity of the slide hole 17, which can ensure that the moving block 7 moves up and down on the surface of the threaded sleeve 6, thereby improving the moving stability of the moving block 7. The screw 5 adopts a countersunk hexagonal internal structure. The screw 5 is driven to rotate by an external tool to achieve the purpose of adjusting the height of the pusher plate 12. The positioning hole 18 is used to install the base plate 1, ensuring the stability of the installation of the base plate 1. The cooperation of fastener 19 and washer 20 connects the positioning block 10 to the connecting plate 9, while also providing a convenient disassembly effect.

[0030] The working principle of this utility model is as follows: the operator connects the external telescopic cylinder to the telescopic plate 3, which can drive the pusher to move horizontally. When assembling circuit boards, the pusher quickly pushes the incoming components. When it is necessary to adjust the height of the pusher plate 12, the screw 5 is rotated. The screw 5 drives the threaded sleeve 6 to move, the threaded sleeve 6 drives the moving block 7 to move, the moving block 7 drives the mounting block 8 to move, the mounting block 8 drives the connecting plate 9 to move, and the connecting plate 9 drives the positioning block 10 to move. The pusher height of the pusher plate 12 below the positioning block 10 can be adjusted flexibly according to the actual pusher position, ensuring the accuracy of the pusher.
