DETAILED DESCRIPTION

[0023] To make the objectives, features, and advantages of this application more readily apparent, the present application is further described below in conjunction with the accompanying drawings and specific embodiments. It is apparent that the embodiments described are only a portion of the embodiments of this application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without inventive effort are also within the scope of protection of this application.

[0024] Reference Figure 1-Figure 2 , shows a circuit board fixing and connecting device of the present invention, which includes a fixed plate 101, a side of which is hingedly provided with a movable clamping member 102, forming a seesaw structure similar to the structure, with a folded angle at the telescopic component 103, which drives it to press toward the fixed plate 101 when it is extended, thereby fixing the circuit board placed on the fixed plate 101 so that it can be connected; the upper end of the movable clamping member 102 is provided with a folded angle toward the fixed plate 101, and the lower end of the movable clamping member 102 is connected to one end of the telescopic component 103, and the other end of the telescopic component 103 is hinged to the lower end of the fixed plate 101; the clamping and release states of the movable clamping member 102 correspond to the telescopic state of the telescopic component 103, and the movable clamping member 102 is driven by the telescopic movement of the telescopic component 103 to achieve clamping and release of the circuit board on the fixed plate 101.

[0025] In the embodiment of the present application, at least two sets of relatively arranged movable clamping members 102 are used, such as Figure 1 and Figure 2 As shown, it can specifically include four movable clamping members, which can be set according to the size of the fixed plate 101. For example, when applied to some larger circuit boards, the clamping members can be appropriately increased, or the above-mentioned movable clamping members 102 can be set on all four sides of the fixed plate. By the extension and contraction of the telescopic component 103, the movable clamping members 102 connected thereto are driven to rotate, so that the folded corners can be pressed against the fixed plate, thereby clamping and fixing the circuit board on the fixed plate 101. When the telescopic component 103 contracts, the circuit board on the fixed plate 101 can be loosened, so that the circuit board can be taken out or the next step of the assembly line operation can be carried out. The present application can realize the rapid fixed connection of the circuit board through the above-mentioned structure, which has the advantages of simple structure, convenient and fast operation, etc., and can greatly improve efficiency and production capacity.

[0026] Next, a circuit board fixing connection device in this exemplary embodiment will be further described.

[0027] In the embodiment of the present application, the lower edge positions of both sides of the fixed plate 101 are fixedly connected with vertical plates 104; the vertical plates 104 are provided with wire blocks; the support plate 201 is arranged on the outside of the vertical plate 104, and is provided with a screw rod 204 connected to the wire block, and the lower end of the screw rod 204 is provided with a transmission wheel 205; the outside of the support plate 201 is provided with a motor 202, and the transmission wheel 205 is connected to the motor 202 through a belt 203.

[0028] The height adjustment of the fixed plate 101 and the circuit board placed thereon is achieved by the cooperation of the screw rod 204 and the wire block on the vertical plate 104, and the motor 202 drives the transmission wheel 205 to rotate the screw rod 204. When the motor 202 is running, the transmission wheel 205 is driven to rotate by the belt 203, thereby rotating the screw rod 204. Since the screw rod 204 is connected to the wire block on the vertical plate 104, and the support plate 201 is relatively fixed and the motor and other structures arranged on its outer side can be regarded as a relatively fixed support base, the rotation of the screw rod 204 will be converted into the up and down movement of the vertical plate 104, thereby achieving the height adjustment of the fixed plate 101. When the operator performs the circuit board processing operation, the circuit board can be adjusted to the height that best suits his operation, reducing the fatigue caused by bending over or raising the hand too high, and improving the comfort and efficiency of the operation. For example, operators of different heights can adjust the circuit board to the appropriate height according to their needs, so that it is more convenient to perform connection operations such as welding and plugging and unplugging cables.

[0029] Through the coordinated work of the fixed plate 101, the movable clamping member 102, the telescopic component 103, etc. On the basis of achieving the fixation of the circuit board, a height adjustment function is further provided, so that the entire device can adjust the height position of the circuit board according to actual needs during use to adapt to different connection operation scenarios and the habits of the operator. For example, when connecting the circuit board with other components, it may be necessary to adjust the circuit board to a suitable height to facilitate the use of operating tools and the observation of the operator. On some production lines, it may be necessary to connect the circuit board to equipment at different heights. At this time, by adjusting the height of the circuit board, docking with various equipment can be easily achieved. At the same time, for different types of circuit board connection operations, such as delicate patch component soldering and larger plug-in installation, different height viewing angles and operating spaces may be required. The height adjustment function can meet these diverse needs.

[0030] A high-precision servo motor can also be used as the control motor 204, and a high-precision screw drive can be used to achieve height adjustment, which has the advantages of high transmission accuracy and good stability. The combination of the screw 204 and the wire block can achieve relatively precise linear motion, ensuring the accuracy of height adjustment. At the same time, the motor 204 drives the transmission wheel 205 through the belt 203 to achieve a certain degree of deceleration and torque amplification, making it easier and more stable to drive the heavier fixed plate 101 and circuit board, and the speed and direction of height adjustment can be accurately controlled by controlling the speed and direction of the motor.

[0031] In the embodiment of the present application, the support plate 201 is further provided with slide rails 206 on both sides of the screw rod 204 ; the vertical plate 104 is provided with sliders 207 , and the sliders 207 are slidably connected to the slide rails 206 .

[0032] By providing a slide rail 206 on the support plate 201 and a matching slider 207 on the vertical plate 104, a guide is provided for the up and down movement of the vertical plate 104. When the screw rod 204 rotates to drive the vertical plate 104 up and down, the slider 207 slides along the slide rail 206, ensuring that the vertical plate 104 can move smoothly in the vertical direction, preventing the vertical plate 104 from shaking or shifting during movement, thereby ensuring the stability of the fixed plate 101 and the circuit board thereon. This effectively prevents shaking and shifting of the vertical plate 104 during movement, making the entire device more stable and reliable during operation. This helps to improve operational safety, avoid accidents such as circuit boards falling due to device instability, and ensure that the height adjustment function always maintains good performance during long-term use, reducing the loss of accuracy due to equipment wear and other reasons.

[0033] In the embodiment of the present application, a tension pulley 208 connected to the belt 203 is further included to control and adjust the tension of the belt 203.

[0034] The tension pulley 208 is connected to the belt 203 and its primary function is to adjust the tension of the belt 203. During operation, the belt 203 may become loose due to prolonged use, or different operating environments and load conditions may require different belt tensions to ensure transmission efficiency and stability. The tension pulley 208 can be adjusted by adjusting its position or applying a certain force to change the tension of the belt 203, ensuring that it always maintains the appropriate operating condition.

[0035] Appropriate belt tension can ensure that there is sufficient friction between the belt 203 and the transmission wheel 205, thereby effectively transmitting the power of the motor 204. When the belt is too loose, it will slip, resulting in power transmission loss, affecting the rotation speed and accuracy of the screw 204, and further affecting the height adjustment effect of the fixed plate 101. By adjusting the belt tension through the tension wheel 208, this situation can be avoided, the transmission efficiency of the device can be guaranteed, and the height adjustment can be carried out quickly and accurately. Maintaining the appropriate tension of the belt can also extend the service life of the belt. A belt that is too loose is prone to wear and breakage, while a belt that is too tight will increase the load on the motor and affect the life of the motor. The tension wheel 208 can adjust the belt tension in real time according to actual conditions, so that the device can maintain stable and reliable operation under various working conditions, reducing equipment downtime and maintenance costs caused by belt failure.

[0036] In the embodiment of the present application, the belt 203 is a toothed belt, and the drive wheel 205 is a toothed pulley. The toothed belt 203 and the drive wheel 205 are designed as toothed pulleys, so that the teeth on the toothed belt can mesh with the teeth of the toothed pulley, making power transmission more precise and stable, and reducing slippage and errors during transmission compared to ordinary belt transmission.

[0037] As an example, a position sensor 209 is provided at the upper end of the support plate 201, facing the fixed plate 101. Position sensor 209 is located at the upper end of the support plate 201, facing the fixed plate 101. Its primary function is to detect the height of the fixed plate 101. By transmitting and receiving signals, position sensor 209 can monitor the position of the fixed plate 101 relative to the support plate 201 in real time and feed this information back to the control system (if the device has a supporting control system).

[0038] Position sensor 209 provides accurate position feedback for height adjustment, allowing the operator to precisely determine the current height of mounting plate 101. During height adjustment, the control system, combined with the preset height value and feedback from the position sensor, precisely controls motor 204, accurately adjusting the circuit board to the desired height. This precise control is crucial for processes requiring strict height control, such as circuit board assembly and testing in automated production lines, improving production efficiency and product quality.

[0039] Position sensor 209 also serves as a safety feature. When fixed plate 101 reaches its upper or lower limit, the position sensor detects this and promptly sends a signal to the control system, which in turn stops motor 204, preventing excessive movement of upright plate 104 that could damage the equipment or cause a safety incident. For example, during equipment commissioning or when a malfunction occurs, the position sensor's safety feature can effectively prevent serious consequences from misoperation or equipment failure, thereby enhancing the safety of the device.

[0040] It should be noted that since the control of the motor such as the servo motor and the telescopic component 103 such as the electric telescopic rod or the cylinder are all conventional existing technologies, they will not be described in detail here.

[0041] In the embodiment of the present application, the movable clamping member 102 has a folded corner and is provided with a rubber pad at least on its surface facing the above-mentioned fixed plate 101, so that the movable clamping member can make soft contact with the circuit board when in contact, which is beneficial to protecting the surface of the edge of the circuit board from being scratched or having obvious indentations.

[0042] In the embodiment of the present application, the telescopic component 103 is an electric telescopic rod or a cylinder.

[0043] The electric telescopic rod can achieve precise telescopic length adjustment to meet the clamping requirements of circuit boards of different sizes and ensure moderate and stable clamping force.

[0044] The cylinder can provide a large clamping force to ensure that the circuit board is firmly fixed during the connection operation and is not easy to loosen. In addition, the cost of the cylinder is relatively low, which has a high cost performance.

[0045] As an example, the rubber pad on the surface of the movable clamping member 102 may be a rubber layer, and a force sensor may be embedded inside it. The pressure sensor is used to detect the pressure of the circuit board on the fixed plate 101. The system can control the operation of the telescopic component 103 according to the detected pressure, thereby driving the movable clamping member 102.

[0046] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0047] Finally, it should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or terminal device.
