Description

Technical Field

[0001] This utility model relates to the field of PCB module processing technology, specifically to a heating rework device. Background Technology

[0002] During the PCB module production process, improper handling or production operations can damage some components on the PCB module, rendering it unusable as a finished product for the customer. Since the entire PCB module is of high value, scrapping it would lead to excessively high production costs. Removing the damaged components and reinstalling the normal ones can effectively reduce production costs.

[0003] Common PCB workpiece heating rework devices utilize a three-axis control system to efficiently and precisely repair PCB workpieces with a cutting tool. During operation, the X-axis controls the horizontal movement of the cutting tool, the Y-axis controls its forward and backward movement, and the Z-axis controls its vertical movement, ensuring good contact between the cutting tool and the PCB workpiece for effective repair. Through the coordinated operation of these three axes, precise repair of complex defects in PCB workpieces is achieved, improving repair quality and efficiency.

[0004] However, in actual use, the cutting tool moves frequently in the Z-axis direction. With long-term use, the slider is prone to jamming along the lead screw, which shortens the service life of the Z-axis linear module. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a heating rework device, which can effectively solve the problem that the frequent movement of the engraving knife in the Z-axis direction can easily cause the slider to jam along the lead screw after long-term use, resulting in a shortened service life of the Z-axis linear module.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a heating rework device, including a workbench, a temperature control box module is provided at the top of the workbench, the temperature control box module is electrically connected to a clamping preheating module, a Y-axis linear module is provided below the clamping preheating module, an X-axis linear module is provided on the side of the workbench away from the temperature control box module, and a Z-axis linear module is provided at the output end of the X-axis linear module.

[0008] The Z-axis linear module includes a bracket fixedly mounted on the top of the X-axis linear module slider. A drive component is rotatably mounted on the top of the bracket. A lead screw is provided at the output end of the drive component. A slider is threadedly connected to the lead screw. A pusher fixing module is fixedly mounted on the slider. Guide rails are slidably connected to both ends of the pusher fixing module. The guide rails are fixedly mounted on the bracket. A top post is provided at the top of the slider. An oil tank is provided above the top post.

[0009] Furthermore, a collection cover is provided at the bottom of the lead screw, and an oil inlet groove is provided at the top of the slider.

[0010] Furthermore, a plug is slidably mounted on the oil reservoir, a push rod is fixedly mounted on the bottom end of the plug, the push rod is slidably connected to a mounting seat, and the mounting seat is fixedly mounted on the inner wall of the oil reservoir.

[0011] Furthermore, the mounting base has an oil flow hole on its surface, and the oil flow hole is in the shape of an inverted frustum.

[0012] Furthermore, a spring is provided at the top of the mounting base, and the end of the spring is fixedly mounted on the plug body.

[0013] Furthermore, a sealing ring is provided around the plug, and the plugs fit together.

[0014] Furthermore, the clamping preheating module includes a heating platform fixedly installed on the top of the sliding component of the Y-axis linear module. A knob is provided on the heating platform, and a threaded rod is provided at the output end of the knob. A clamping plate is threadedly connected to the threaded rod, and a buffer is provided on the side of the clamping plate away from the threaded rod.

[0015] Furthermore, a sliding groove is provided on the surface of the heating platform, and a clamping plate is slidably connected inside the sliding groove. A conductive component is provided inside the heating platform, and the conductive component is electrically connected to a temperature control box module.

[0016] Beneficial effects

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] I. This utility model achieves precise supply of lubricant by moving the slider upward, causing the top column to press the push rod, which in turn moves the plug body upward and opens the oil tank channel. This makes the slider slide more smoothly on the lead screw, greatly reduces wear between components, and extends the service life of parts.

[0019] II. Through the coordinated operation of multi-directional linear modules, the X-axis linear module drives the Z-axis linear module to move along the X-axis. The Z-axis linear module uses a drive component, lead screw and slider to make the pusher fixing module move precisely in the Z-axis. The Y-axis linear module moves in coordination below the clamping preheating module, realizing the flexible movement of the engraving tool in three-dimensional space, accurately completing the heating rework operation of different positions of the PCB workpiece, and improving the accuracy and flexibility of processing.

[0020] Third, this utility model effectively clamps PCB workpieces of different sizes using a knob, threaded rod, and clamping plate. The buffer is used to prevent the workpiece from being damaged due to excessive clamping force. At the same time, the temperature control box module transfers heat to the heating table through the conduction component to heat the PCB workpiece. Furthermore, the position of the workpiece in the Y-axis direction can be easily adjusted by adjusting the Y-axis linear module, which meets the needs of different processing positions and optimizes the clamping and heating effect.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] A heating rework device, see attached. Figure 1 - Figure 5 The system includes a workbench 1, a temperature control box module 2 at the top of the workbench 1, a clamping preheating module 7 electrically connected to the temperature control box module 2, a Y-axis linear module 5 below the clamping preheating module 7, an X-axis linear module 3 on the side of the workbench 1 away from the temperature control box module 2, and a Z-axis linear module 4 at the output end of the X-axis linear module 3.

[0031] Z-axis linear module 4 includes a bracket 405 fixedly mounted on the top of the sliding member of X-axis linear module 3. A drive member 401 is rotatably mounted on the top of the bracket 405. A lead screw 402 is provided at the output end of the drive member 401. A slider 403 is threadedly connected to the lead screw 402. A pusher fixing module 6 is fixedly mounted on the slider 403. Guide rails 404 are slidably connected to both ends of the pusher fixing module 6. The guide rails 404 are fixedly mounted on the bracket 405. A top post 414 is provided at the top of the slider 403. An oil tank 406 is provided above the top post 414. The worktable 1 provides stable support for the entire device. The temperature control box module 2 controls the temperature and is electrically connected to the clamping preheating mold. Block 7 preheats the PCB workpiece. The X-axis linear module 3 drives the Z-axis linear module 4 at its output end to move along the X-axis. In the Z-axis linear module 4, the drive component 401 rotates, causing the lead screw 402 to rotate, which drives the slider 403, which is threaded to it, to move precisely along the guide rail 404 in the Z-axis. The engraving knife fixing module 6 on the slider 403 moves accordingly, so that the push knife on the push knife fixing module 6 repairs the PCB board. The oil bag 406 above the top column 414 provides lubrication for the moving parts. At the same time, the Y-axis linear module 5 cooperates below the clamping preheating module 7 to realize the flexible movement of the engraving knife in three-dimensional space, completing the heating and rework operation of the PCB workpiece.

[0032] Furthermore, a collection cover 413 is provided at the bottom of the lead screw 402, and an oil inlet groove 415 is provided at the top of the slider 403. The oil inlet groove 415 is used to guide the lubricating fluid to flow accurately to the contact part between the lead screw 402 and the slider 403, so as to provide good lubrication for the relative movement between the lead screw 402 and the slider 403, reduce friction and wear, and extend the service life of the components. The collection cover 413 collects excess lubricating fluid in a concentrated manner, and the lubricating fluid in the collection cover 413 can be cleaned periodically, which greatly simplifies the cleaning work and improves maintenance efficiency.

[0033] Furthermore, a plug body 410 is slidably installed in the oil reservoir 406, and a push rod 407 is fixedly installed at the bottom end of the plug body 410. The push rod 407 is slidably connected to a mounting seat 408, and the mounting seat 408 is fixedly installed on the inner wall of the oil reservoir 406.

[0034] Furthermore, the mounting base 408 has an oil flow hole 412 on its surface. The oil flow hole 412 is in the shape of an inverted frustum. When the lubricant enters the inverted frustum-shaped oil flow hole 412 from the larger inlet, the flow rate of the lubricant will be relatively faster due to the gradual decrease in the diameter of the hole. Specifically, the shape of the inverted frustum-shaped oil flow hole 412, which is wider at the top and narrower at the bottom, makes it easier for the lubricant to enter the oil flow hole 412 from the larger inlet under the action of gravity or oil pressure, reducing the resistance when the lubricant flows in, allowing the lubricant to enter the oil flow hole 412 more smoothly, and then quickly flow to the parts that need lubrication, thereby improving the lubrication efficiency.

[0035] Furthermore, a spring 409 is provided at the top of the mounting base 408. The end of the spring 409 is fixedly mounted on the plug body 410. The spring 409 provides an upward elastic force to the plug body 410, so that the plug body 410 is in a certain position in the initial state. When the lead screw 402 needs lubrication, the spring 409 is stretched by force. At this time, the oil passage is opened, and the lubricant in the oil tank 406 flows out smoothly to lubricate the lead screw 402. When it is necessary to close the oil passage, the control slider 403 moves down, and the downward rebound force of the spring 409 makes the plug body 410 return to the initial position, closing the oil passage and preventing excessive flow of lubricant, thereby realizing the on-demand supply of lubricant.

[0036] Furthermore, a sealing ring 411 is provided around the plug body 410, and the plug bodies 410 fit together. The sealing ring 411 can effectively prevent the lubricant from leaking out from the gap between the plug body 410 and the inner wall of the oil tank 406. The fit between the plug bodies 410 further enhances the sealing effect, ensuring that the lubricant remains inside the oil tank 406 when the plug body 410 is not subjected to external force, thus maintaining a good sealing environment.

[0037] Furthermore, the clamping preheating module 7 includes a heating platform 706 fixedly mounted on the top of the sliding member of the Y-axis linear module 5. A knob 701 is provided on the heating platform 706, and a threaded rod 702 is provided at the output end of the knob 701. A clamping plate 703 is threadedly connected to the threaded rod 702. A buffer 704 is provided on the side of the clamping plate 703 away from the threaded rod 702. The heating platform 706 serves as the base platform for the clamping preheating module, providing stable support for the placement and clamping of the PCB workpiece. Specifically, the PCB workpiece is placed on the heating platform 706, and the knob 701 is rotated according to the size of the PCB workpiece. The knob 701 drives the threaded rod 702 to rotate. The mechanism moves the clamping plate 703 along the extension direction of the slide groove 707 via the thread action, thereby effectively clamping PCB workpieces of different sizes. When the clamping plate 703 clamps the PCB workpiece, the buffer 704 directly contacts the workpiece, absorbing and dispersing part of the pressure applied to the PCB workpiece by the clamping plate 703, playing a role in buffering and shock absorption, and preventing damage to the PCB workpiece due to excessive squeezing force from the clamping plate 703 during the clamping process. By adjusting the Y-axis linear module 5, the clamping preheating module 7 moves along the Y-axis direction, making it easy to adjust the position of the PCB workpiece in the Y-axis direction to meet the needs of different processing positions.

[0038] Furthermore, a sliding groove 707 is provided on the surface of the heating table 706, and a clamping plate 703 is slidably connected inside the sliding groove 707. A conductive component 705 is provided inside the heating table 706, and the conductive component 705 is electrically connected to the temperature control box module 2. By controlling the temperature control box module 2, the conductive component 705 transfers the generated heat to the heating table 706, and then to the PCB workpiece placed on the heating table 706, thereby achieving the heating of the PCB workpiece.

[0039] Working principle: During use, the PCB workpiece is placed on the heating table 706. The clamping plate 703 is controlled by rotating the knob 701 to effectively clamp PCB workpieces of different sizes. Then, the X-axis linear module 3 is operated to control the position of the engraving knife on the X-axis, the Z-axis linear module 4 is operated to control the position of the engraving knife on the Z-axis, and the Y-axis linear module 5 is operated to control the position of the PCB board on the Y-axis, thereby realizing the repair of different positions of the PCB board. The temperature required for PCB board processing is controlled by operating the temperature control box module 2.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
