Description

Technical Field

[0001] This utility model relates to the field of electronic device disassembly and assembly technology, specifically to an ECU circuit board disassembly device. Background Technology

[0002] The electronic control unit (ECU) has a removable circuit board. When it is necessary to remove the circuit board from the ECU, the common method is for the operator to remove it by hand with a soldering gun. This method requires the operator to have a high level of experience. However, different operators have different levels of proficiency and operating techniques, which often leads to damage to the connectors of the circuit board during the disassembly and assembly process. For example, accidental contact with components may cause problems such as faulty points, affecting its function and service life. Utility Model Content

[0003] This utility model addresses the technical problems existing in the prior art by providing an ECU circuit board disassembly device that enables rapid disassembly of the circuit board while reducing defects caused by manual disassembly.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an ECU circuit board disassembly device, including a support assembly, and a lifting assembly and an ejection assembly used in conjunction with the support assembly;

[0005] The lifting component is located on the upper part of the ejection component and is slidably connected to it. When used together, there is a gap between the upper end face of the ejection component and the support component for placing the product to be disassembled. After the ejection component is connected to the product to be disassembled, it presses the product to be disassembled onto the support component during the downward pressing process of the lifting component, and removes the circuit board on the product to be disassembled by the ejection component during the lifting process of the lifting component.

[0006] As a further technical solution, the support component includes a frame-shaped base, a supporting base, and a guide connector;

[0007] The receiving base is disposed inside the frame-shaped base and connected by the guide connector. The gap between its outer edge and the inner edge of the frame-shaped base is opposite, and the lower end face of the receiving base is above the lower end face of the base, so that the receiving base is pressed down or lifted relative to the frame-shaped base during the pressing down or lifting of the lifting assembly.

[0008] When used together, the lifting assembly and the ejection assembly are both located above the receiving base, and the ejection assembly is connected to the receiving base through the product to be disassembled.

[0009] As a further technical solution, the receiving base is provided with a groove that matches the lower part of the product to be disassembled, and the lower part of the ejector assembly is opposite to the groove.

[0010] As a further technical solution, at least two guide connectors are provided, and they are symmetrically arranged on both sides of the receiving base;

[0011] The guide connector includes a guide post, a telescopic spring, a guide connector block with a 7-shaped longitudinal section, and a limiting block. The telescopic spring is sleeved on the guide post, and the upper and lower ends of the telescopic spring abut against the short side of the guide connector block and the upper end of the base, respectively.

[0012] The guide post passes through the through hole on the short side of the guide connecting block and abuts against the base.

[0013] The long side of the guide connecting block is pressed against the upper surface of the receiving base. The limiting block is fixed in the gap between the upper surface of the receiving base and the guide connecting block, so that the guide connecting block slides up and down with the guide column during the up and down movement of the receiving base, and the limiting block restricts the downward sliding height of the guide connecting block.

[0014] As a further technical solution, the lifting assembly includes a guide shaft, a lifting guide block, a pressing part, and a handle;

[0015] The guide shaft is inserted into the lifting guide block and coaxial with it, and its top end extends out of the lifting guide block and is threadedly connected to the pressing part. The handle is threadedly connected to the upper part of the lifting guide block. By pressing the handle, the circuit board on the product to be disassembled connected to the lower end face of the ejection assembly is ejected and removed.

[0016] The ejector assembly is slidably connected to the lower part of the lifting guide block. By pressing down or lifting the handle, the lifting guide block is driven to push the product to be disassembled, which is connected to the lower end face of the ejector assembly, to descend or rise.

[0017] As a further technical solution, the lifting guide block includes a vertical part, a connecting part, and a sliding part;

[0018] The vertical part is perpendicularly connected to the connecting part, and two sliding parts are provided and symmetrically arranged on both sides of the connecting part. The guide shaft is vertically arranged in the vertical part, and its bottom extends out of the connecting part and enters the ejection assembly.

[0019] The sliding part is slidably connected to the ejection assembly.

[0020] As a further technical solution, the ejection assembly includes a connecting plate and an ejector pin;

[0021] The connecting plate is provided with at least two pins that are slidably connected to it, and when the pins are in use, their bottoms are opposite to the upper surface of the receiving base;

[0022] The connecting plate is located on the lower end face of the connecting part and is connected through the guide shaft. The two sides of the connecting plate are symmetrically provided with notches that are slidably connected to the sliding part, so that the sliding guide block moves away from or contacts the connecting plate during the sliding process.

[0023] As a further technical solution, the ejection assembly also includes two fastening blocks, which are symmetrically arranged on both sides of the sliding guide block and stacked on the upper surface of the connecting plate.

[0024] The beneficial effects of this utility model are: the combined design of the support component, lifting component and ejection component can realize the rapid removal of the circuit board on the ECU product. At the same time, the device can effectively reduce the problem of accidental contact with components and defects caused by manual welding gun removal. It is easy to operate and suitable for promotion.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the described features.

[0038] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0039] This embodiment provides a simple, easy-to-operate, and low-skill disassembly device for ECU circuit boards. (See attached image) Figure 1 , Figure 2The device mainly includes a support component 1, a lifting component 2, and an ejection component 3 used in conjunction with the support component 1. The support component 1 is used to support the lifting component 2, the ejection component 3, and the product 4 to be disassembled during use. When the device is not in operation, the lifting component 2 and the ejection component 3 are placed on the support component 1 and do not need to be fixedly connected. Specifically, the lifting component 2 is located on the upper part of the ejection component 3 and is slidably connected to it. When used together, there is a gap between the upper end face of the ejection component 3 and the support component 1 for placing the product 4 to be disassembled. After the ejection component 3 is connected to the product 4 to be disassembled, it presses the product 4 to be disassembled onto the support component 1 during the downward pressing of the lifting component 2, and the product 4 is pressed onto the support component 1 during the lifting process of the lifting component 2. The circuit board on the product 4 to be disassembled is ejected and removed by the ejector component 3. That is, in the non-working state, the lifting component 2 and the ejector component 3 can be placed on the support component 1 after assembly, but the connection between the ejector component 3 and the support component 1 is not fixed and can be a contact connection. In the working state, the device is first placed above the solder pot, and then the product 4 to be disassembled is inserted into the lower part of the ejector component 3. The product 4 to be disassembled is stacked on the upper surface of the support component 1. The solder joints are melted by the internal solder flow. By manually pressing the lifting component 2 to raise or lower, the upper surface of the product is moved to contact or away from the ejector component 3. At the same time, the ejector component 3 is always connected to the product. After the circuit board on the product is ejected and removed by the lifting component 2, the product rises with the lifting component 2.

[0040] In the specific implementation process, see Figure 1 , Figure 2 The support assembly 1 includes a frame-shaped base 11, a receiving base 12, and a guide connector 13. The receiving base 12 is disposed within the frame-shaped base 11 and connected by the guide connector 13. The outer edge of the receiving base 12 is aligned with the inner edge of the frame-shaped base 11, and the lower end face of the receiving base 12 is above the lower end face of the frame-shaped base 11 to form a height difference. This allows the receiving base 12 to descend or ascend relative to the frame-shaped base 11 during the downward or upward movement of the lifting assembly 2. When used in conjunction with the lifting assembly 2... Both the lowering component 2 and the ejection component 3 are located above the receiving base 12. The ejection component 3 is connected to the receiving base 12 via the product to be disassembled 4. That is, in the non-working state, due to the supporting effect of the guide connector 13, there is a gap between the lower end face of the receiving base 12 and the upper end face of the frame base 11. When in the working state, the receiving base 12 slides along the axis of the guide connector 13 under pressure. For structural aesthetics and balanced force distribution, the frame base 11 and the receiving base 12 are co-centered.

[0041] More specifically, the receiving base 12 has a groove 121 adapted to the lower part of the product 4 to be disassembled, and the lower part of the ejector assembly 3 is opposite to the groove 121. More specifically, since the circuit board on the product 4 to be disassembled is opposite to the groove 121, the shape of the groove 121 is adapted to the shape of the circuit board and is slightly larger than the size of the circuit board.

[0042] To ensure even force distribution, at least two guide connectors 13 are provided, symmetrically arranged on both sides of the receiving base 12; for ease of observation, it is preferable to provide two guide connectors 13. Specifically, each guide connector 13 includes a guide post 131, a telescopic spring 132, a guide connecting block 133 with a longitudinal section of type 7, and a limiting block 134. The telescopic spring 132 is sleeved on the guide post 131, and the upper and lower ends of the telescopic spring 132 respectively abut against the surface of the short side of the guide connecting block 133 and the upper surface of the frame base 1, so that the guide connector 13 slides down along the guide post 131 under the pulling action of the receiving base 12. At this time, the telescopic spring 132 is subjected to a downward compressive force by the guide connector 13. When the downward pressure of the receiving base 12 disappears, due to the rebound force of the telescopic spring 132, the guide connector 13 is pushed upward along the axis of the guide post 131. The guide post 131 passes through the through hole on the short side of the guide connecting block 133 and abuts against the frame base 11. The long side of the guide connecting block 133 is pressed against the upper end face of the receiving base 12. The limiting block 134 is fixed in the gap between the upper end face of the receiving base 12 and the guide connecting block 133, so that when the guide connecting block 133 moves downward under the tension of the receiving base 12, it can not continue to move downward when it reaches the upper end face of the limiting block 134, which is its maximum range. That is, the sliding height of the guide connecting block 133 is limited to the distance from the upper end face of the limiting block 134 to the lower end face of the short side of the guide connecting block 133. To prevent the guide connecting block 133 from detaching from the guide post 131, the guide connecting block 133 is provided with a limiting pad 135, and the limiting pad 135 is sleeved on the part of the guide post 131 that is exposed on the upper end face of the guide connecting block 133.

[0043] In the specific implementation process, see Figure 1-Figure 4The lifting assembly 2 includes a guide shaft 21, a lifting guide block 22, a pressing part 23, and a handle 24. The lifting guide block 22 has a through hole for the guide shaft 21 to pass through. The guide shaft 21 is inserted into the lifting guide block 22 and coaxial with it, with its top end extending out of the lifting guide block 22 and threadedly connected to the pressing part 23. The handle 24 is threadedly connected to the upper part of the lifting guide block 22. For ease of operation, two handles 24 can be provided, symmetrically arranged on both sides of the lifting guide block 22. By pressing the handle 24, the circuit board on the product 4 to be disassembled, connected to the lower end face of the ejection assembly 3, can be ejected and removed. The ejection assembly 3 is slidably connected to the lower part of the lifting guide block 22. By pressing down or lifting the handle 24, the lifting guide block 22 can be driven to push the product 4 to be disassembled, connected to the lower end face of the ejection assembly 3, to descend or rise.

[0044] More specifically, the lifting guide block 22 includes a vertical part 221, a connecting part 222, and a sliding part 223; the vertical part 221 is perpendicularly connected to the connecting part 222, and two sliding parts 223 are provided and symmetrically arranged on both sides of the connecting part 222, with the lower end of one of the two sliding parts 223 being longer than the other, which facilitates guidance;

[0045] The guide shaft 21 is vertically mounted on the vertical part 221, and its bottom extends out of the connecting part 222 and enters the ejector assembly 3. This allows the vertical part 221 to slide along the axis of the guide shaft 21 under the push of the handle 24, thereby driving the connecting part 222 and the sliding part 223 to slide. During this process, the connecting part 222 presses down on the ejector assembly 3, and the ejector assembly 3 presses down on the product 4 to be disassembled and secures its lower part within the groove 121 of the receiving base 12. The sliding part 223... The ejector assembly 3 is blocked on both sides, causing it to slide coaxially, thus improving its stability and accuracy. Similarly, when the connecting part 222 is lifted, the lower end face of the connecting part 222 will move away from the upper end face of the ejector assembly 3, while the lower end face of the ejector assembly 3 remains inserted into the product 4 to be disassembled. The sliding part 223 is slidably connected to the ejector assembly 3. Preferably, the vertical part 221, the connecting part 222, and the sliding part 223 are integrally formed to provide stability and accuracy.

[0046] In the specific implementation process, see Figure 1 , Figure 2 , Figure 5The ejector assembly 3 includes a connecting plate 31 and ejector pins 32. The connecting plate 31 has at least two ejector pins 32 slidably connected to it. When in use, the bottom of each ejector pin 32 faces the upper surface of the receiving base 12. That is, the ejector pins 32 are not fixedly connected to the receiving base 12, but are placed on the receiving base 12 in a contact-type connection. Depending on the specific structure of the product to be disassembled, the lower structures of several ejector pins 32 can be different to adapt to the product to be disassembled. The connecting plate 31 is located on the lower surface of the connecting part 222 and is connected via the guide shaft 21. When the handle 24 is pressed down... The lifting assembly 2 slides down along the guide shaft 21. At this time, a gap is formed between the lower end face of the connecting part 222 and the upper end face of the connecting plate 31. The product 4 to be disassembled is inserted into the groove 121 under the pressure of the connecting plate 31. The product 4 to be disassembled undergoes hot melting soldering in the solder pot. After a few seconds, the handle 24 is pulled upward, and the pressing part 23 is pressed at the same time. The downward pressure of the pressing part 23 is transmitted to the guide shaft 21 and the connecting part 222 in sequence. The ejector pin 32 on the connecting part 222 transmits the pressure to the circuit board on the product 4 to be disassembled, thereby realizing the removal of the circuit board from the ECU.

[0047] To facilitate sliding with the sliding part 223, the connecting plate 31 has symmetrically provided recesses 311 on both sides for sliding connection with the sliding part 223, so that the sliding part 223 slides up and down along the recesses 311, while the lifting guide block 22 moves away from or contacts the connecting plate 31 during sliding. To enhance the pressure and the stability of the lifting assembly 2 and the ejection assembly 3, the ejection assembly 3 also includes two fastening blocks 33, which are symmetrically arranged on both sides of the lifting guide block 22 and stacked on the upper surface of the connecting plate 31. That is, the connecting plate 31 and the fastening blocks 33 are connected by screws, and the fastening blocks 33 abut against the side opposite to the connecting part 222, so that the two fastening blocks 33 clamp the connecting part 222 in the middle and slide up and down together with the lifting guide block 22.

[0048] This utility model is implemented as follows:

[0049] First, connect the base, the receiving base 12 and the guide connector 13 and place them above the solder pot. Then, fix the product 4 to be disassembled below the ejector assembly 3, that is, insert the ejector pin 32 into the product 4 to be disassembled, and make the top of the ejector pin 32 located inside the connecting plate 31 (that is, the connecting plate 31 is lifted to the highest limit). Then, place the lifting assembly 2 and the ejector assembly 3 with the product 4 to be disassembled on the base, press the handle 24, so that the ejector assembly 3 and the product 4 to be disassembled fall into the solder pot for hot melting solder joints for a few seconds, then lift the handle 24 and press the pressing part 23 at the same time, so that the ejector pin 32 falls down and ejects the circuit board at the bottom of the product 4 to be disassembled, so as to finally complete the disassembly operation.

[0050] This embodiment enables rapid removal of circuit boards while effectively reducing defects caused by manual soldering, improving removal efficiency, extending the service life of circuit boards, and features a simple structure and convenient operation, making it suitable for widespread application.

[0051] It should be noted that, in the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0052] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0053] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
