Description

Technical Field

[0001] This utility model relates to the field of patch generation technology, and in particular to a pin patching device, mechanism and workstation. Background Technology

[0002] In the electronics manufacturing industry, pin insertion and PCB placement are two critical production steps. Currently, most production lines use separate pin insertion and placement machines to perform these two tasks. This approach has the following problems:

[0003] 1. Inserting pins and mounting PCB boards are done on separate machines, which reduces equipment utilization.

[0004] 2. When placing circuit boards, the pick-and-place equipment needs to also place other components. However, since the circuit boards are heavier than other components, there is a great risk of the circuit boards falling off when the pick-and-place machine moves at high speed, which greatly affects the operating speed of the pick-and-place machine.

[0005] 3. Materials need to be transferred between different devices, which increases production time and labor costs, making it difficult to achieve efficient automated production.

[0006] Therefore, an integrated pin-mount device and workstation are needed to optimize the production process and solve the above problems. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a pin insertion and patching device, mechanism and workstation, which solves the problems of low equipment utilization, low operating efficiency and increased production costs caused by using two independent devices to complete the pin insertion and circuit board patching operations in the prior art.

[0008] To solve the above-mentioned technical problems, this utility model provides a pin insertion and surface mount device, compatible with pin insertion operations and circuit board surface mount operations, including:

[0009] Fixing plate;

[0010] A pin assembly includes a pin vertical guide rail and a pin drive unit disposed on a fixed plate, a pin mounting plate slidably disposed on the pin vertical guide rail, a pin head and a pin ejection structure disposed on the pin mounting plate, the pin drive unit being connected to the pin mounting plate and driving the pin mounting plate to slide vertically along the pin vertical guide rail, and the pin ejection structure being used to push the pin inside the pin head;

[0011] The patch assembly includes a patch vertical guide rail and a patch driver fixed to a fixed plate, and a nozzle head slidably disposed on the patch vertical guide rail for adsorbing the circuit board. The patch driver drives the nozzle head to slide vertically along the patch vertical guide rail.

[0012] As a more preferred embodiment, the mounting assembly further includes a rotary motor mounted on the second vertical guide rail and connected to the nozzle head to adjust the angle of the circuit board adsorbed on the nozzle head. The advantage of this is that the addition of the rotary motor allows for adjustment of the angle of the circuit board adsorbed on the nozzle head, enabling the circuit board to be angled according to actual needs during the mounting process. This improves the flexibility and adaptability of the mounting operation and can meet the mounting requirements of circuit boards of different shapes and sizes.

[0013] As a more preferred embodiment, the pin assembly further includes a pin sensing plate disposed on a pin mounting plate. The mounting plate is provided with multiple vertical displacement sensors for sensing the pin sensing plate, arranged vertically. When the pin head is obstructed from downward alignment, the pin head experiences an upward reaction force. The pin mounting plate rises under the action of this reaction force. The vertical displacement sensors detect the pin sensing plate and, through the pin drive component, cause the pin mounting plate to rise and avoid obstruction. The advantages are that the inclusion of the pin sensing plate and vertical displacement sensors allows for timely detection and prompts the pin mounting plate to rise and avoid obstruction when the pin head is obstructed from downward alignment, preventing damage to the pin head due to excessive force, improving the device's self-protection capability and reliability, and extending the device's service life.

[0014] As a more preferred embodiment, the placement assembly further includes a placement sensor sheet disposed on the vertical guide rail for placement, and the fixing plate is provided with a plurality of vertical displacement sensors for sensing the placement sensor sheet, the plurality of vertical displacement sensors being arranged vertically; the advantage of this is that the placement assembly adds a placement sensor sheet and vertical displacement sensors, which can monitor the vertical position of the nozzle head in real time during the placement process, ensuring the placement accuracy of the circuit board and improving the stability of product quality.

[0015] To address the above problems, this utility model provides a pin-mounting mechanism, comprising:

[0016] Horizontal movement device;

[0017] The aforementioned pin patch device is mounted on the horizontal moving device, which drives the pin patch device to move horizontally.

[0018] As a more preferred embodiment, the horizontal moving device includes an X-axis guide rail, a Y-axis guide rail slidably mounted on the X-axis guide rail, an X-axis drive component, and a Y-axis drive component. The pin placement device is slidably mounted on the Y-axis guide rail. The X-axis drive component drives the Y-axis guide rail to slide along the X-axis guide rail, and the Y-axis guide rail drives the pin placement device to slide along the Y-axis guide rail. Its advantages lie in that the horizontal moving device, using the X-axis guide rail, Y-axis guide rail, and corresponding drive components, forms a two-dimensional planar moving system, which can precisely control the position of the pin placement device in the horizontal plane, improving the accuracy and automation of the operation, and making pin placement and patching operations more efficient and accurate.

[0019] To address the aforementioned problems, this utility model also provides a pin-mount workstation, comprising:

[0020] The mounting platform and the aforementioned pin patch mechanism are mounted on the mounting platform.

[0021] The mounting platform includes a rotating arm, a pin feeding mechanism, and a feeder. The feeder comprises a hopper structure holding pins and circuit boards, and a robotic arm. The robotic arm picks up pins and circuit boards from the hopper structure and delivers them to the pin feeding mechanism and the rotating arm. The pin feeding mechanism feeds the pins into the pin head, and the rotating arm transports the circuit boards to the bottom of the nozzle head. The horizontal moving device, the pin assembly, and the surface mount assembly drive the pins and circuit boards to the target position, completing the pin insertion operation and the circuit board surface mount operation.

[0022] As a more preferred embodiment, the pin-mounting workstation also includes a solenoid valve assembly connected to the rotating arm and the pin-mounting mechanism. The solenoid valve assembly includes a solenoid valve and a vacuum generator to generate positive and negative pressure air sources. Its advantage lies in that by setting up the solenoid valve assembly, including the solenoid valve and the vacuum generator, positive and negative pressure air sources can be generated to provide power support for the various pneumatic components of the pin-mounting workstation, ensuring the normal operation of components such as the nozzle head and the rotating arm, and improving the operational stability and efficiency of the workstation.

[0023] As a more preferred embodiment, the rotary swing arm includes a swing arm drive, a rotating arm with one end connected to the output shaft of the swing arm drive, and a limiting plate disposed at the other end of the rotating arm. The limiting plate has a limiting hole. The other end of the rotating arm is connected to a solenoid valve assembly. The negative pressure air source generated by the solenoid valve assembly is used to adsorb the circuit board onto the limiting hole of the limiting plate. The swing arm drive drives the circuit board to rotate in the horizontal direction. Its advantage is that the design of the rotary swing arm can use the negative pressure air source to adsorb the circuit board and realize the rotation of the circuit board in the horizontal direction under the drive of the swing arm drive, so that the circuit board can be adjusted to a suitable position and angle for surface mount technology (SMT) operation, increasing the flexibility and adaptability of SMT operation.

[0024] In a more preferred embodiment, the pin feeding mechanism includes a feeding base, a sliding block, a first feeding tube, a positioning cover, and a feeding drive. The feeding base has a feeding groove and a first air inlet. Both ends of the first feeding tube are connected to the feeding groove and the pin head, respectively. The air inlet is connected to the solenoid valve assembly. The positioning cover seals the feeding groove from the top, and a positioning groove adapted to the pin is provided in the middle of the positioning cover. The sliding block is slidably disposed within the feeding groove, and has elongated holes adapted to the pin extending vertically. The sliding block is connected to the feeding drive, and the feeding drive moves the sliding block between the feeding position and the stop position within the feeding groove. In the movement; in the stop position, the robotic arm grasps the pin and places it in the positioning groove. The pin is located on top of the sliding block. The feeding drive drives the sliding block to the feeding position. The elongated hole aligns with the positioning groove. The pin falls from the elongated hole into the feeding groove. The solenoid valve group blows air through the first air inlet, blowing the pin into the pin head through the first feeding tube. Its beneficial effect is that the design of the pin feeding mechanism can realize the automatic feeding of the pin. Through the cooperation of the feeding base, sliding block, feeding tube, positioning cover and drive, the pin can be accurately fed into the pin head, improving the efficiency and accuracy of pin insertion operation, reducing manual operation and reducing labor intensity.

[0025] As described above, the pin insertion and placement device, mechanism, and workstation of this utility model have the following beneficial effects: In use, the integrated design of the pin insertion assembly and the placement assembly enables simultaneous pin insertion and circuit board placement operations on a single device, improving production efficiency, reducing equipment footprint, and lowering production costs. The vertical guide rail and drive unit of the pin insertion assembly work together to precisely control the vertical movement of the pin mounting plate, ensuring accurate pin insertion; similarly, the placement assembly controls the movement of the nozzle head through the vertical guide rail and drive unit, achieving precise circuit board placement and ensuring product quality; furthermore, by combining pin insertion and circuit board placement operations, the independently set component placement machine can maintain high-speed operation throughout the process, improving component placement efficiency; finally, it reduces material transfer between different devices, achieving more efficient automated production.

[0026] The pin insertion and surface mount mechanism of this utility model sets the pin insertion and surface mount device on a horizontal moving device, so that the device can move in the horizontal direction, expanding the working range and enabling pin insertion and surface mount operations on circuit boards at different positions, improving the versatility and flexibility of the equipment and adapting to diverse production needs.

[0027] The pin placement workstation of this utility model integrates pin placement mechanism, rotary swing arm, pin feeding mechanism and feeder through the installation platform, realizing an automated production process from raw material supply to finished product output, improving production efficiency and product quality, and reducing labor costs and labor intensity.

[0028] In summary, the pin insertion and board mounting device, mechanism, and workstation of this utility model solve the problems of low equipment utilization, low operating efficiency, and increased production costs caused by using two separate devices to complete the pin insertion and board mounting operations in the prior art by combining the pin insertion operation with the board mounting operation.

[0092] like Figure 1As shown, this utility model provides a pin placement device 41, compatible with pin insertion operations and circuit board placement operations, including:

[0093] Fixing plate 415;

[0094] The pin assembly includes a pin vertical guide rail 421 and a pin drive 417 disposed on a fixed plate 415, a pin mounting plate 420 slidably disposed on the pin vertical guide rail 421, a pin head 422 disposed on the pin mounting plate 420, and a pin ejection structure 418. The pin drive 417 is connected to the pin mounting plate 420 and drives the pin mounting plate 420 to slide vertically along the pin vertical guide rail 421. The pin ejection structure 418 is used to push the pin in the pin head 422.

[0095] The patch assembly includes a patch vertical guide rail 411 and a patch driver 412 fixed on a fixing plate 415, and a suction head 425 slidably disposed on the patch vertical guide rail 411 for adsorbing the circuit board. The patch driver 412 drives the suction head 425 to slide vertically along the patch vertical guide rail 411.

[0096] To better illustrate the pin insertion and placement device 41 of this utility model, the following specific application will be used as an example: In use, the pin insertion and placement device 41 integrates the pin insertion assembly and the placement assembly, enabling simultaneous pin insertion and circuit board placement operations on a single device. This improves production efficiency, reduces equipment footprint, and lowers production costs. The vertical guide rail and drive unit of the pin insertion assembly precisely control the vertical movement of the pin mounting plate 420, ensuring accurate pin insertion. Similarly, the placement assembly controls the movement of the nozzle head 425 via the vertical guide rail and drive unit, achieving precise circuit board placement and ensuring product quality. Furthermore, by combining pin insertion and circuit board placement operations, the independently configured component placement machine can maintain high-speed operation throughout the process, improving component placement efficiency. Finally, it reduces material transfer between different devices, achieving more efficient automated production.

[0097] In some possible embodiments of this utility model, such as Figure 1 As shown, the mounting assembly also includes a rotary motor 424, which is mounted on the second vertical guide rail. The rotary motor 424 is connected to the suction head 425 to adjust the angle of the circuit board adsorbed on the suction head 425. The beneficial effect is that by adding the rotary motor 424, the angle of the circuit board adsorbed on the suction head 425 can be adjusted, allowing the circuit board to be angled according to actual needs during the mounting process. This improves the flexibility and adaptability of the mounting operation and can meet the mounting requirements of circuit boards of different shapes and sizes.

[0098] In some possible embodiments of this utility model, such as Figure 1 As shown, the rotary motor 424 is a hollow servo motor, and the patch assembly also includes a rotary joint 423 disposed on the patch vertical guide rail 411. One end of the hollow servo motor is connected to the rotary joint 423, and the other end is connected to the suction head 425. The beneficial effect is that by using a hollow servo motor and setting the rotary joint 423, the air tube can pass through the middle of the hollow servo motor and connect to the suction head 425, which optimizes the structural layout, reduces the problem of air tube entanglement and interference, and improves the operational stability and reliability of the device. At the same time, the hollow servo motor has high precision and response speed, and can more accurately control the angle adjustment of the circuit board.

[0099] In some possible embodiments of this utility model, such as Figure 1 As shown, the patch assembly also includes a patch negative pressure gauge 413 connected to the suction head 425 via an air tube. The patch negative pressure gauge 413 detects the vacuum level inside the suction head 425 to determine whether the circuit board has been successfully picked up. The air tube passes through the middle of the central control servo motor and is connected to the suction head 425. The beneficial effect is that by detecting the vacuum level inside the suction head 425 through the patch negative pressure gauge 413, it is possible to accurately determine whether the circuit board has been successfully picked up, thereby improving the reliability and accuracy of the patch operation and effectively avoiding production accidents and product quality problems caused by failure to pick up the circuit board.

[0100] In some possible embodiments of this utility model, such as Figure 1 As shown, the pin assembly also includes a pin sensing plate 419 disposed on the pin mounting plate 420. A plurality of vertical displacement sensors 416 are disposed on the fixing plate 415 to sense the pin sensing plate 419, and the plurality of vertical displacement sensors 416 are arranged vertically. When the pin head 422 is obstructed from downward pin insertion, the pin head 422 receives an upward reaction force. The pin mounting plate 420 rises under the action of the reaction force. The vertical displacement sensors 416 detect the pin sensing plate 419 and, through the pin drive component 417, drive the pin mounting plate 420 to rise and avoid obstruction. The beneficial effect is that by providing the pin sensing plate 419 and the vertical displacement sensors 416, when the pin head 422 is obstructed from downward pin insertion, it can be detected in time, causing the pin mounting plate 420 to rise and avoid obstruction, preventing damage to the pin head 422 due to excessive force, improving the self-protection capability and reliability of the device, and extending the service life of the equipment.

[0101] In some possible embodiments of this utility model, the pin assembly further includes a pin ejection structure. When the downward pin insertion of the pin head 422 is obstructed, the pin mounting plate 420 rises under the action of the reaction force. The vertical displacement sensor 416 detects the pin sensing plate 419 and drives the pin mounting plate 420 to rise to the pin ejection position through the pin drive member 417. The pin is then ejected through the pin ejection structure. The beneficial effect is that by adding the pin ejection structure, when the downward pin insertion of the pin head 422 is obstructed, not only can the pin mounting plate 420 rise to avoid the obstruction, but the pin can also be ejected through the pin ejection structure, preventing the pin from getting stuck in the pin head 422. This further improves the reliability and operating efficiency of the device and reduces manual intervention and maintenance time.

[0102] In some possible embodiments of this utility model, the pin drive 417 and the pin ejection structure 418 are cylinders, and the patch drive 412 is a motor. The advantage is that the specific types of the pin drive 417, the pin ejection structure 418 and the patch drive 412 are clearly defined. The combined use of cylinders and motors can give full play to their respective advantages. The cylinder provides greater force for the pin insertion and ejection actions, while the motor can accurately control the vertical movement of the patch, thereby improving the overall performance and working efficiency of the device.

[0103] In some possible embodiments of this utility model, such as Figure 1 As shown, the patch assembly also includes a patch sensing chip 414 disposed on the patch vertical guide rail 411, and a plurality of vertical displacement sensors 416 disposed on the fixing plate 415 for sensing the patch sensing chip 414, the plurality of vertical displacement sensors 416 being arranged vertically; the beneficial effect is that the patch assembly adds the patch sensing chip 414 and the vertical displacement sensors 416, which can monitor the vertical position of the nozzle head 425 in real time during the patching process, ensuring the patching accuracy of the circuit board and improving the stability of product quality.

[0104] In some possible embodiments of this utility model, such as Figure 1 As shown, the fixing plate 415 is provided with three vertical displacement sensors 416 for sensing the pin sensing piece 419. The three vertical displacement sensors 416 are arranged vertically, and the pin sensing piece 419 and the patch sensing piece 414 share the three vertical displacement sensors 416. The beneficial effect is that the pin sensing piece 419 and the patch sensing piece 414 share the three vertical displacement sensors 416, which optimizes the sensor configuration, reduces the complexity and cost of the equipment, and improves the utilization rate of the sensors, thereby enhancing the integration and compactness of the device.

[0105] In some possible embodiments of this utility model, such as Figure 1As shown, both the pin sensing plate 419 and the patch sensing plate 414 are provided with grooved mounting holes. Locking members are used to pass through the corresponding grooved mounting holes to fix the pin sensing plate 419 and the patch sensing plate 414 to the pin mounting plate 420 and the patch vertical guide rail 411, respectively. The vertical position of the pin sensing plate 419 and the patch sensing plate 414 can be fine-tuned by adjusting the locking members in the grooved mounting holes. The beneficial effect is that by providing grooved mounting holes on the pin sensing plate 419 and the patch sensing plate 414 and using locking members for fixation, it is convenient to fine-tune the vertical position of the sensing plates. The sensing position can be flexibly adjusted according to actual conditions, improving the adaptability and accuracy of the device and enhancing the controllability of the production process.

[0107] Horizontal moving device 43;

[0108] The aforementioned pin patch device 41 is mounted on the horizontal moving device 43, which drives the pin patch device 41 to move horizontally.

[0109] To better illustrate the pin insertion and surface mount mechanism 4 of this utility model, the following specific application will be used as an example: The pin insertion and surface mount mechanism 4 of this utility model sets the pin insertion and surface mount device 41 on the horizontal moving device 43, so that the device can move in the horizontal direction, expanding the working range and enabling pin insertion and surface mount operations on circuit boards at different positions, thereby improving the versatility and flexibility of the equipment and adapting to diverse production needs.

[0110] In some possible embodiments of this utility model, such as Figure 2 As shown, the horizontal moving device 43 includes an X-axis guide rail 431, a Y-axis guide rail 432 slidably disposed on the X-axis guide rail 431, an X-axis drive component, and a Y-axis drive component. The pin placement device 41 is slidably disposed on the Y-axis guide rail 432. The X-axis drive component drives the Y-axis guide rail 432 to slide along the X-axis guide rail 431, and the Y-axis guide rail 432 drives the pin placement device 41 to slide along the Y-axis guide rail 432. Its beneficial effect is that the horizontal moving device 43, using the X-axis guide rail 431, the Y-axis guide rail 432, and the corresponding drive components, forms a two-dimensional planar moving system, which can accurately control the position of the pin placement device 41 in the horizontal plane, improve the accuracy and automation of the operation, and make the pin placement and patching operation more efficient and accurate.

[0113] The rotating arm 3, the pin feeding mechanism 21, and the feeder 2 are installed on the installation platform 1. The feeder 2 includes a hopper structure 23 that holds pins and circuit boards and a robot arm 24. The robot arm 24 grabs the pins and circuit boards from the hopper structure 23 and feeds them to the pin feeding mechanism 21 and the rotating arm 3. The pin feeding machine feeds the pins into the pin head 422. The rotating arm 3 transports the circuit board to the bottom of the nozzle head 425. The horizontal moving device 43, the pin assembly, and the surface mount assembly drive the pins and circuit boards to the target position to complete the pin insertion operation and the circuit board surface mount operation.

[0114] To better illustrate the pin placement workstation of this utility model, the following specific application will be used as an example: The pin placement workstation of this utility model integrates the pin placement mechanism 4, the rotating swing arm 3, the pin feeding mechanism 21, and the feeder 2 through the mounting platform 1, realizing an automated production process from raw material supply to finished product output, improving production efficiency and product quality, and reducing labor costs and labor intensity. It can be seen that the pin placement device, mechanism, and workstation of this utility model solve the problems of low equipment utilization, low operating efficiency, and increased production costs caused by using two separate devices to complete the pin placement and circuit board placement operations in the prior art by combining the pin placement operation with the circuit board placement operation.

[0115] In some possible embodiments of this utility model, such as Figure 4 As shown, the pin placement workstation also includes a vision system. The hopper structure 23 includes a large hopper 231 and a small hopper 232. The loose pins and circuit components are directly placed in the large hopper 231. The robotic arm 24 picks up the loose components from the large hopper 231 and transfers them to the small hopper 232. The vision system determines the orientation and other parameters of the loose components in the small hopper 232, and the robotic arm 24 adsorbs and transfers them to the designated position, reducing pallet and tray costs. Its beneficial effects are that the addition of a vision system and the use of the large and small hoppers 231 and 232 structure enable automatic picking, identification, and placement of loose pins and circuit board components, reducing reliance on pallets and trays, lowering production costs. At the same time, the vision system can determine the orientation and other parameters of the loose components, improving the automation and accuracy of the production process.

[0116] In some possible embodiments of this utility model, such as Figure 3As shown, the pin placement workstation also includes a conveyor track 5, which is located in front of the pin placement mechanism 4, the rotating arm 3, the pin feeding mechanism 21 and the feeder 2, to meet the transportation of workpieces to be inserted and placed on circuit boards, and to be transported out from the other end of the conveyor track 5 after the operation is completed.

[0117] In some possible embodiments of this utility model, such as Figure 4 As shown, the feeder 2 also includes a mounting base 22 disposed at the bottom, and the mounting base 22 is fixed on the mounting platform 1.

[0118] In some possible embodiments of this utility model, the feeder 2 is a flexible feeder 2; its advantages are that the feeder 2 is a flexible feeder 2, which can adapt to pins and circuit boards of different shapes, sizes and materials, improves the flexibility and reliability of feeding, enhances the workstation's adaptability to different products, and reduces the adjustment time and cost when changing production.
