Description

Technical Field

[0001] This utility model relates to the field of patch technology, specifically to an anti-displacement patch device. Background Technology

[0002] SMT is one of the most popular technologies and processes in the electronics assembly industry. Surface mount technology is a technology that mounts leadless or short-lead surface mount components onto the surface of a printed circuit board or other substrates and then assembles them by reflow soldering or dip soldering.

[0003] Chinese Patent Publication No. CN218830821U discloses an anti-displacement placement device for SMT placement machines in electronics factories. The device includes a base plate, with a placement platform fixedly connected to its upper surface. Vertical plates are fixedly connected to the left and right sides of the upper surface of the placement platform. A top plate is fixedly connected to the upper surfaces of the two vertical plates. A motor is started, driving a lead screw to rotate. Two movable blocks are movably connected to the outer wall of the lead screw, which is a bidirectional lead screw. This causes the two movable blocks to move synchronously towards each other, further driving two connecting rods to move towards each other. This causes the movable plate and clamping plate on the upper surface of the placement platform to move synchronously towards each other, thereby clamping and fixing the substrate firmly through the two clamping plates. This ensures the substrate is securely fixed, preventing displacement and maintaining it in a fixed position. Components can be accurately placed, greatly guaranteeing product quality. The placement controller controls a cylinder, causing the cylinder output to drive the placement frame to rise and fall for placement work.

[0004] However, in the process of applying the patch to the workpiece, the contact surface of the workpiece is subjected to the force of the clamping plate, which can easily cause damage to the workpiece. Therefore, there is an urgent need for an anti-displacement patching device. Utility Model Content

[0005] The purpose of this invention is to provide an anti-displacement patch device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an anti-displacement patch device, including a clamping mechanism, wherein a patching mechanism is provided on the clamping mechanism;

[0007] The clamping mechanism includes a worktable with a cavity inside. A bidirectional lead screw is rotatably mounted inside the cavity. Moving plates are threaded onto the surfaces of the bidirectional lead screw with its positive and negative threads, respectively. A housing is fixedly connected to the top of each moving plate. A first slider is slidably mounted inside each housing. A clamping plate is fixedly connected to the ends of the first sliders that are close to each other, and a first spring is fixedly connected to the ends of the first sliders that are far apart from each other. A rubber pad is fixedly connected to the end of each clamping plate that is far away from the first slider. A first motor is fixedly connected to the left side of the worktable.

[0008] Preferably, the top of the workbench has two sliding grooves, and the movable plates are slidably disposed in the sliding grooves respectively.

[0009] The workpiece is placed on the worktable between two clamping plates. The first motor drives the bidirectional lead screw to rotate, which in turn drives the two moving plates to move inward in the sliding groove at the same time. This causes the outer shell to move and the clamping plates to move, thus clamping the workpiece.

[0010] Preferably, the left side of the bidirectional lead screw is fixedly connected to the first motor via a movable through-worktable, and a support leg is fixedly connected to the bottom of the worktable.

[0011] Preferably, the end of the first spring away from the first slider is fixedly connected to the outer casing, and multiple first springs are provided.

[0012] The first spring reduces the rigid force on the workpiece when it is clamped, and the rubber pad provides protection when the workpiece is clamped again.

[0013] Preferably, the patching mechanism includes two supports, the tops of the two supports are fixedly connected to the same top beam, the top beam has a horizontal groove, a screw is rotatably disposed in the horizontal groove, a moving block is threadedly connected to the surface of the screw, an electric push rod is fixedly connected to the bottom of the moving block, a push block is fixedly connected to the bottom of the electric push rod, a groove is formed at the bottom of the push block, a second slider is slidably disposed in the groove, a second spring is fixedly connected to the top of the second slider, a patching frame is fixedly connected to the bottom of the second slider, and a second motor is fixedly connected to the left side of the top beam.

[0014] Preferably, multiple second springs are provided, and the tops of the multiple second springs are respectively fixedly connected to the top wall of the groove.

[0015] Two brackets are fixed on both sides of the workbench to support the top beam. The screw is driven to rotate by the second motor, which in turn drives the moving block to move horizontally along the transverse groove. The moving block drives the electric push rod to move to the patching position.

[0016] Preferably, the left side of the screw is fixedly connected to the second motor via a movable through-beam, and the moving block is slidably disposed in the transverse groove.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] Firstly, in this utility model, the workpiece is placed on the worktable between two clamping plates. A first motor drives a bidirectional lead screw to rotate, which in turn moves the two moving plates inward simultaneously within the sliding groove. This causes the outer shell and clamping plates to move accordingly, thus clamping the workpiece. The first spring reduces the rigid force on the workpiece during clamping, while the rubber pad provides protection when clamping the workpiece again. The rubber pad also increases friction, ensuring the stability of the workpiece during mounting and preventing damage when the workpiece is clamped and fixed.

[0019] Secondly, in this utility model, two brackets are fixed on both sides of the workbench to support the top beam. The screw is driven to rotate by the second motor, which in turn drives the moving block to move horizontally along the transverse groove. The moving block drives the electric push rod to the patching position. When the electric push rod pushes down, the patching frame contacts the workpiece to perform the patching operation. The patching frame is used to place and attach circuit boards or other workpieces that need to be patched. The bottom of the push block has a groove to accommodate the second slider and ensure its stable movement in the vertical direction. The second spring is connected between the second slider and the groove to provide elastic support and ensure that the patching frame reduces the rigid force on the workpiece during the patching process.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1 , Figure 2 and Figure 4 An anti-displacement patch device includes a clamping mechanism, on which a patching mechanism is provided;

[0029] The clamping mechanism includes a worktable 11, which has a cavity inside. A bidirectional lead screw 12 is rotatably mounted inside the cavity. Moving plates 13 are threaded to the surfaces of the bidirectional lead screw 12 with positive and negative threads, respectively. A housing 14 is fixedly connected to the top of the moving plates 13. First sliders 15 are slidably mounted inside the housings 14. Clamping plates 16 are fixedly connected to the ends of the first sliders 15 that are close to each other. First springs 17 are fixedly connected to the ends of the first sliders 15 that are far from each other. Rubber pads 18 are fixedly connected to the ends of the clamping plates 16 that are far from the first sliders 15. A first motor 19 is fixedly connected to the left side of the worktable 11.

[0030] The top of the workbench 11 has two sliding grooves, and the movable plates 13 are slidably disposed in the sliding grooves respectively.

[0031] The left side of the bidirectional lead screw 12 is fixedly connected to the first motor 19 via a movable through-worktable 11, and the bottom of the worktable 11 is fixedly connected to a support leg 20.

[0032] The end of the first spring 17 away from the first slider 15 is fixedly connected to the outer shell 14, and multiple first springs 17 are provided.

[0033] With the above technical solution, when performing patch mounting, the workpiece is placed on the worktable 11, positioned between the two clamping plates 16. The first motor 19 drives the bidirectional lead screw 12 to rotate, thereby causing the two moving plates 13 to move inward simultaneously within the sliding groove. This causes the outer shell 14 to move accordingly, and the clamping plates 16 to move accordingly, thus clamping the workpiece. The first spring 17 reduces the rigid force on the workpiece when it is clamped. The rubber pad 18 provides protection when clamping the workpiece again, and also increases friction, ensuring the stability of the workpiece during patch mounting and preventing damage when the workpiece is clamped and fixed.

[0034] Example 2

[0036] Multiple second springs 28 are provided, and the tops of the multiple second springs 28 are respectively fixedly connected to the top wall of the groove.

[0037] The left side of the screw 23 is fixedly connected to the second motor 30 through the movable through-beam 22, and the moving block 24 is slidably set in the transverse groove.

[0038] Through the above technical solution, two brackets 21 are fixed on both sides of the workbench 11 to support the top beam 22. The second motor 30 drives the screw 23 to rotate, which in turn drives the moving block 24 to move horizontally along the transverse groove. The moving block 24 drives the electric push rod 25 to move to the patching position. When the electric push rod 25 pushes downward, the patch frame 29 contacts the workpiece to perform patching. The patch frame 29 is used to place and bond circuit boards or other workpieces that need to be patched. The bottom of the push block 26 has a groove to accommodate the second slider 27 and ensure its stable movement in the vertical direction. The second spring 28 is connected between the second slider 27 and the groove to provide elastic support and ensure that the patch frame 29 reduces the rigid force on the workpiece during the patching process.
