Description
Technical Field
[0001] The utility model belongs to the technical field of clamping structures, in particular to a PCB board clamping device for a chip mounter. Background Art
[0002] Mounter: Also known as "mounting machine" or "surface mount system" (Surface Mount System). In the production line, it is configured after the dispensing machine or screen printer. It is a device that accurately places surface mount components on the PCB pads by moving the mounting head. The circuit board can be called a printed circuit board or printed circuit board, and the English name is (Printed Circuit Board) PCB.
[0003] The PCB clamping mechanism of the SMT machine is an indispensable part of the SMT machine, which is mainly used for clamping and positioning the PCB board. At present, most PCB board clamping mechanisms adopt a clamping method composed of a fixed plate, a movable plate, a guide rod, a guide rod fixing bracket, a spring and a spring fixing clamp. When adjusting the clamping width of the PCB board, the spring fixing clamp must be loosened, and then adjusted to a suitable position and then clamped, so it is extremely inconvenient to adjust. Moreover, due to the structure of the fixed plate and the movable plate, the applicability of the clamping mechanism is often not strong, and it is difficult to adapt to PCB boards of different specifications and shapes. Therefore, the utility model proposes a PCB board clamping device for a SMT machine to solve the above problems. Utility Model Content
[0004] The utility model proposes a PCB board clamping device for a chip placement machine, which can adapt to PCB boards of different specifications and shapes. By adjusting the position and angle of a driving member and an active slider, stable clamping of different PCB boards can be achieved. At the same time, the entire clamping process is automatically completed by a control system, which reduces manual operation and intervention and improves production efficiency.
[0005] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a PCB board clamping device for a placement machine, comprising an operating table, a placement machine is installed on the operating table, a transmission component is installed below the placement machine, a clamping component is transmission-connected to the transmission component, the clamping component comprises a fixed plate, a driving member is fixedly connected to the fixed plate, an active slider is fixedly connected to the output end of the driving member, the active slider is a Y-shaped structure, and guide grooves are provided on both sides of the active slider away from the driving member, and driven sliders are embedded in the guide grooves.
[0006] An opening is arranged on the fixed plate, an auxiliary clamp is fixedly connected to one side of the opening, sliding grooves are arranged on the other three sides of the opening, and convex blocks matching the sliding grooves are arranged at the bottom of the active slider and the driven slider.
[0007] The following beneficial effects are achieved by adopting the above scheme: when in use, the PCB board is placed on the auxiliary clamp, and the first cylinder is started by the controller, and the first cylinder drives the active slider to move, so that the driven slider can slide in the guide groove as the active slider moves, and maintain synchronous movement with the active slider. When the active slider and the driven slider are retracted inward at the same time, they clamp and fix the PCB board on the auxiliary clamp. Due to the prismatic joint design of the active slider and the driven slider, they can ensure synchronous movement during the clamping process, thereby achieving stable clamping of the PCB board.
[0008] The prismatic joint design of the active slider and the driven slider can maintain synchronous movement during the clamping process, achieve stable clamping of the PCB board, and improve production efficiency. The movement of the active slider and the driven slider is precisely controlled by the controller, which can ensure the accurate positioning of the PCB board during the clamping process, thereby improving product quality. The entire process is automatically completed by the control system and mechanical structure, reducing manual operation and intervention, reducing the possibility of errors and errors, and improving the degree of automation of the production process. The clamping device has a simple structure, is easy to install and maintain, and reduces production costs. The clamping device has a stable structure and safe operation, reducing the safety risks of operators and equipment.
[0009] Furthermore, the transmission component includes a guide rail, one end of which is fixedly connected to a power member, the output end of the power machine is fixedly connected to a fixed plate, and the fixed plate is slidably matched with the guide rail.
[0010] Beneficial effects: The design of the guide rail and the power piece enables the transmission assembly to have a stable transmission function. The power piece can provide stable power to ensure that the PCB board will not shake or deviate during the transmission process. Through the cooperation of the power piece and the guide rail, the PCB board can be transmitted quickly and efficiently. The design of the guide rail can ensure the stability of the PCB board during the transmission process and reduce unnecessary pauses and delays.
[0011] Furthermore, both the active slider and the driven slider are provided with mounting grooves, a spring is fixedly connected in the mounting groove, one end of the spring away from the mounting groove is fixedly connected with a cylinder, and the cylinder is slidably matched with the mounting groove.
[0012] Beneficial effect: When the active slider and the driven slider are retracted inward at the same time, the limit groove of the cylinder clamps the outer edge of the PCB board. The PCB board is stably fixed on the auxiliary clamp. At this time, the spring plays a shock-absorbing role, alleviating the impact force during the clamping process, and further ensuring the stability and accuracy of the PCB board. By accurately controlling the coordination of the spring and the cylinder, the stability and accuracy of the PCB board can be ensured, thereby improving product quality. By using the design of the spring, the reliability and durability of the equipment can be enhanced, and the number of failures and repairs can be reduced.
[0013] Furthermore, a limiting groove is provided at one end of the cylinder away from the spring.
[0014] Beneficial effects: The design of the limit groove can increase the stability of the clamping device, prevent the PCB board from sliding or shaking during processing, and ensure the stability and accuracy of the product. The limit groove can limit the movement range of the PCB board to prevent it from accidentally sliding out of the clamping device or falling, thereby reducing the safety risk of the device. The limit groove can reduce the friction and wear between the PCB board and the clamping device, thereby extending the service life of the clamping device.
[0015] Furthermore, a motor is fixedly connected to the opening of the fixing plate, and an output end of the motor is fixedly connected to the auxiliary clamp.
[0016] Beneficial effects: By pre-clamping the PCB board, then releasing the clamp after processing, and starting the motor, the motor rotates the PCB board through the auxiliary clamp, making the entire processing process more efficient. By rotating the parallel PCB board to a vertical state, the PCB board is prevented from being damaged or scratched during the sliding process, thereby improving the quality and consistency of the product. The entire process is automatically completed by the control system and mechanical structure, reducing manual operation and intervention, and reducing the possibility of errors and errors.
[0017] Furthermore, a protective layer is fixedly connected to the limiting groove and the auxiliary clamp.
[0018] Beneficial effects: The protective layer can protect the limit slot and auxiliary clamp from wear, corrosion and external impact, and extend their service life. The limit slot and auxiliary clamp are important components of the clamping device. By fixing and connecting the protective layer, their rigidity and stability can be increased, and the accuracy and stability of clamping can be improved. The limit slot and auxiliary clamp are the parts that directly contact the PCB board. If they are worn or corroded, they may cause damage to the PCB board. By fixing and connecting the protective layer, the damage to the PCB board can be reduced, and the quality and stability of the product can be improved.
[0019] Furthermore, the clamping device includes a controller, which is connected to the driving member, the power member and the motor signal.
[0020] Beneficial effects: Through the signal connection between the controller and the driver, power and motor, the automatic control of the clamping device can be realized. The controller can automatically adjust the working parameters of the driver, power and motor according to the preset program or the external input signal to realize the automatic clamping and processing of the PCB board. Since the controller can accurately control the driver, power and motor, the clamping device can work efficiently and stably. Whether in continuous production or batch production, stable production efficiency and product quality can be maintained. When the equipment fails or the parameters need to be adjusted, it can be remotely monitored and controlled through the controller to quickly solve the problem.
[0021] Furthermore, a temperature sensor is installed on the active slider, and the temperature sensor is connected to the controller signal.
[0022] Beneficial effects: By using a temperature sensor to monitor the temperature of the PCB board in real time during processing by the SMT machine, it is possible to ensure that the temperature during processing is within an appropriate range, which helps to improve the quality and stability of the product and reduce the defective product rate. If the processing temperature is too high or too low, the controller can adjust the working parameters or issue an alarm in time to avoid overheating or overcooling, thereby protecting the device from damage, helping to extend the service life of the equipment and improve production efficiency.

For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.
[0028] The following is further described in detail through specific implementation methods:
[0029] The figure marks in the drawings of the specification include: operating table 1, placement machine 2, fixing plate 3, first cylinder 301, opening 302, slide groove 303, active slider 4, driven slider 401, auxiliary clamp 5, guide rail 6, second cylinder 601, cylinder 7, limit groove 701, motor 8.
[0030] Embodiment 1, basically as attached Figure 1 and Figure 2 As shown: a PCB board clamping device for a placement machine, including an operating table 1, a placement machine 2 is installed on the operating table 1, a transmission component is installed below the placement machine 2, the transmission component is transmission-connected with a clamping component, the clamping component includes a fixed plate 3, a driving member is fixedly connected to the fixed plate 3, an active slider 4 is fixedly connected to the output end of the driving member, the active slider 4 is a Y-shaped structure, and guide grooves are provided on both sides of the active slider 4 away from one end of the driving member, and driven sliders 401 are embedded in the guide grooves.
[0031] The transmission assembly includes a guide rail 6 , one end of which is fixedly connected to a power member, an output end of the power machine is fixedly connected to a fixed plate 3 , and the fixed plate 3 and the guide rail 6 are slidably matched.
[0032] The fixing plate 3 is provided with an opening 302 , an auxiliary clamp 5 is welded and fixed on one side of the opening 302 , and sliding grooves 303 are provided on the other three sides of the opening 302 . The bottoms of the active slider 4 and the driven slider 401 are provided with protrusions matching the sliding grooves 303 .
[0033] The clamping device comprises a controller, which is connected with the driving member and the power member by signals.
[0034] In this embodiment, the controller uses a single chip microcomputer of model HT66F30, the driving part is the first cylinder 301, and the power part is the second cylinder 601. The first cylinder 301 and the second cylinder 601 are both of the model: Jingong CJ1B.
[0035] The specific implementation process is as follows: when in use, the PCB board is placed on the auxiliary clamp 5, and the first cylinder 301 is started by the controller. The first cylinder 301 will drive the active slider 4 to move, so that the driven slider 401 can slide in the guide groove as the active slider 4 moves, and maintain synchronous movement with the active slider 4. When the active slider 4 and the driven slider 401 are simultaneously retracted inward, they will clamp and fix the PCB board on the auxiliary clamp 5. Due to the prismatic joint design of the active slider 4 and the driven slider 401, they can ensure that they maintain synchronous movement during the clamping process, thereby achieving stable clamping of the PCB board. Then, the second cylinder 601 drives the conveying component to convey the PCB board to the bottom of the placement machine 2 for processing. After the processing is completed, the first cylinder 301 is controlled by the controller to drive the active slider 4. When the active slider 4 and the driven slider 401 are simultaneously opened outward, the processed PCB board cancels the clamping. When the clamping is released, the PCB board will fall downward from the opening 302 of the fixed plate 3, which is convenient for workers to perform subsequent operations and processing.
[0036] The prismatic joint design between the active slider 4 and the driven slider 401 ensures synchronous movement during the clamping process, thereby achieving stable clamping of the PCB board. By controlling the cooperation of the driving member and the power member through the controller, the clamping force and position of the active slider 4 and the driven slider 401 can be adjusted to adapt to PCB boards of different sizes. Through the automated clamping device, manual intervention can be reduced, reducing the impact of human factors on product quality. Through the automated clamping device, the time and error of manual operation can be reduced, and production efficiency can be improved. Stable clamping and precise control can ensure the accurate position and angle of the PCB board, thereby improving product quality and consistency.
[0037] Embodiment 2 is different from the above embodiment in that: both the active slider 4 and the driven slider 401 are provided with mounting grooves, a spring is welded and fixed in the mounting grooves, a cylinder 7 is welded and fixed at one end of the spring away from the mounting groove, and the cylinder 7 is slidably matched with the mounting groove. A limiting groove 701 is provided at one end of the cylinder 7 away from the spring. A protective layer is pasted and fixed in the limiting groove 701 and the auxiliary clamp 5.
[0038] The specific implementation process is as follows: when the active slider 4 and the driven slider 401 are simultaneously retracted inward, the limit groove 701 of the cylinder 7 clamps the outer edge of the PCB board. The PCB board is stably fixed on the auxiliary clamp 5. At this time, the spring plays a shock-absorbing role, alleviates the impact force during the clamping process, and further ensures the stability and accuracy of the PCB board. The protective layer fixed in the limit groove 701 and the auxiliary clamp 5 plays a protective role, preventing the PCB board from being damaged or scratched during the clamping process. The design of the spring and the protective layer further improves the quality and consistency of the product.
[0039] Embodiment 3 is different from the above embodiments in that: the opening 302 of the fixing plate 3 is fixedly connected with the motor 8 by bolts, and the output end of the motor 8 is fixedly welded to the auxiliary clamp 5. The motor 8 is connected to the controller signal.
[0040] The specific implementation process is as follows: when processing the PCB board, the auxiliary clamp 5 pre-clamps the PCB board. When the processing is completed, the clamping of the processed PCB board is cancelled. When the clamping is released, the motor 8 is started by the controller, and the output shaft of the motor 8 drives the auxiliary clamp 5, and the auxiliary clamp 5 rotates an angle to rotate the parallel PCB board to a vertical state, so that the PCB board slides off the auxiliary clamp 5, thereby preventing the PCB board from being damaged or scratched during the sliding process, and improving the quality and consistency of the product.
[0041] By clamping the PCB board in advance, and then releasing the clamping and rotating the PCB board as needed, the processed PCB board can be smoothly dropped, thereby improving production efficiency. The entire process is automatically completed by the control system and the mechanical structure, reducing manual operation and intervention, and reducing the possibility of errors and errors. Through precise clamping and rotation, the stability and accuracy of the PCB board can be ensured, thereby improving product quality. The processed PCB board is slid off the auxiliary clamp 5, making subsequent operations more convenient.
[0042] Embodiment 4 is different from the above embodiments in that a temperature sensor is installed on the active slider 4, and the temperature sensor is connected to the controller signal. The model of the temperature sensor used in this embodiment is TD80.
[0043] The specific implementation process is as follows: By using a temperature sensor to monitor the temperature of the PCB board in real time during processing by the SMT machine 2, it can be ensured that the temperature during the processing is within an appropriate range, which helps to improve the quality and stability of the product and reduce the defective product rate. If the processing temperature is too high or too low, the controller can adjust the working parameters or issue an alarm in time to avoid overheating or overcooling, thereby protecting the device from damage, helping to extend the service life of the equipment and improve production efficiency.
[0044] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the invention and the practicality of the patent.
