Description

Technical Field

[0001] This utility model relates to the field of circuit board surface mount production line technology, and in particular to a dual-track docking station with adjustable width. Background Technology

[0002] A PCB surface mount technology (SMT) production line is used to automatically mount electronic components onto PCBs. It typically includes, in sequence, a board loading machine, solder paste printing machine, solder paste inspection machine, component mounting machine, mounting inspection machine, and cooling machine. Adjacent machines are connected by a transfer platform to transport PCBs. To improve processing efficiency, some manufacturers employ a dual-line synchronous processing solution. Between the mounting inspection and cooling machines on the two production lines, a transfer machine and an adjustable-width double-rail transfer platform are installed. The transfer machine transports PCBs from the mounting inspection machines on both lines to the adjustable-width double-rail transfer platform. The adjustable-width double-rail transfer platform then transports the PCBs from the transfer machine to the cooling machine, which simultaneously cools the PCBs from both production lines.

[0003] Currently, adjustable-width dual-rail docking stations generally include two conveyor modules for transporting circuit boards. Each module includes two conveyor belts and an adjustment mechanism for adjusting the distance between the two conveyor belts. One conveyor belt is fixed, and the other is a movable conveyor belt. The adjustment mechanism moves the movable conveyor belt, thereby adjusting the width between the fixed and movable conveyor belts. During the docking process between the adjustable-width dual-rail docking station and transplanting or cooling equipment, the entire adjustable-width dual-rail docking station must first be moved according to the position of the transplanting or cooling equipment until the fixed conveyor belt of the adjustable-width dual-rail docking station is aligned with the transmission mechanism of the transplanting or cooling equipment. Then, the adjustment mechanism moves the movable conveyor belt of the adjustable-width dual-rail docking station to adjust the distance between the fixed and movable conveyor belts, making the distance between them compatible with the width of the transmission mechanism of the transplanting or cooling equipment, ultimately allowing them to dock with the transmission mechanism of the transplanting or cooling equipment. This docking method requires moving the entire width-adjustable double-track docking platform, resulting in poor docking flexibility and making the docking process quite difficult.

[0004] Therefore, how to provide a width-adjustable dual-track docking station technology that can simplify the docking process with other devices has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a dual-track docking platform with adjustable width, which is simpler to connect with other equipment compared to the prior art.

[0006] This utility model is achieved using the following technical solution: An adjustable-width dual-track docking station includes a frame and conveying modules: the frame includes a guide structure; two conveying modules are configured, each conveying module including a conveying drive mechanism, an electric screw mechanism, a locking assembly, and two conveyor belts, the two conveyor belts being configured to support opposite sides of a circuit board; the conveying drive mechanism is configured to drive the two conveyor belts to convey the circuit board along a conveying direction; each conveyor belt is slidably connected to the guide structure in a first direction perpendicular to the conveying direction; the electric screw mechanism is configured to drive one of the two conveyor belts to slide reciprocally relative to the guide structure in the first direction; the locking assembly is connected to the guide structure and to the other of the two conveyor belts, when the locking assembly is locked, the locking assembly prevents the corresponding conveyor belt from sliding reciprocally relative to the guide structure in the first direction, and when the locking assembly is unlocked, the corresponding conveyor belt can move reciprocally relative to the guide structure in the first direction.

[0007] In one alternative embodiment, the guide structure includes a guide rod, and the conveyor belt is slidably sleeved on the guide rod along the axial direction of the guide rod.

[0008] In one alternative embodiment, the locking assembly includes a clamp capable of locking onto a guide rod and unlocking from the guide rod, the clamp being secured to the corresponding conveyor belt by fasteners.

[0009] In one optional embodiment, the clamp includes a fixed seat and a screw. The fixed seat is fixed to the conveyor belt by fasteners. The fixed seat has a "C"-shaped wrapping groove and two cantilever arms extending outward from both sides of the opening of the wrapping groove. The wrapping groove is inserted into a guide rod. One of the two cantilever arms has an assembly hole and the other has a threaded hole. The screw rod passes through the assembly hole and is threadedly connected to the threaded hole.

[0010] In one alternative embodiment, the electric lead screw mechanism includes a lead screw shaft and a lead screw motor, the lead screw shaft being rotatably connected to the frame and threadedly connected to a corresponding transmission belt, and the lead screw motor being configured to drive the lead screw shaft to rotate in both directions.

[0011] In one optional embodiment, the conveying drive mechanism includes a connecting shaft and a drive motor, the connecting shaft being rotatably connected to the frame; the output shaft of the drive motor being drivenly connected to the connecting shaft; and both conveyor belts being drivenly connected to the connecting shaft.

[0012] In one optional embodiment, the conveyor belt includes a support plate, a conveyor belt, a drive pulley, and a plurality of driven pulleys; the drive pulley and the plurality of driven pulleys are rotatably mounted on the support plate; the conveyor belt is sleeved on the drive pulley and the plurality of driven pulleys; the connecting shaft is prismatic in shape, the shaft of the drive pulley is a hollow tube, the inner cavity shape of the hollow tube is adapted to the shape of the connecting shaft, the hollow tube is sleeved on the connecting shaft, and when the connecting shaft rotates, it can drive the hollow tube to rotate synchronously.

[0013] In one alternative implementation, all the conveyor belts are arranged side by side along a first direction.

[0014] In one optional embodiment, a control unit is also included; the conveying module further includes a position sensor for detecting the relative position of the two conveyor belts. The position sensor and the electric lead screw mechanism are both electrically connected to the control unit. After receiving the detection signal fed back by the position sensor, the control unit can control the electric lead screw mechanism to drive the corresponding conveyor belt to slide relative to the guide structure in a first direction.

[0015] In one optional embodiment, the position sensor is a proximity switch, which includes a sensing head and a sensing plate. The sensing head is located on one of the two conveyor belts, and the sensing plate is located on the other of the two conveyor belts. When the sensing head contacts the sensing plate, the sensing head and / or the sensing plate feed back a detection signal to the control unit.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Both conveyor belts of this application can slide back and forth along a first direction onto a guide structure. An electric screw mechanism drives one of the two conveyor belts to slide back and forth relative to the guide structure along the first direction. A locking assembly secures the other conveyor belt to the sliding structure. During the docking of the width-adjustable double-rail docking platform with the conveying mechanism of other equipment, the locking assembly is first unlocked, and then the corresponding conveyor belt is manually pushed to slide along the guide structure until it aligns with one side of the external equipment's conveying mechanism. The locking assembly is then locked, preventing the conveyor belt from sliding relative to the guide structure, thus completing the positioning of the conveyor belt. Next, the electric screw mechanism drives the other conveyor belt to slide relative to the guide structure until it aligns with the other side of the external equipment's conveying mechanism. Finally, the two conveyor belts of the width-adjustable double-rail docking platform are docked with both sides of the external equipment's conveying mechanism. Compared with the prior art, the adjustable-width double-rail docking platform of this application does not require adjusting the position of the two conveyor belts by moving the adjustable-width double-rail docking platform during docking with external equipment. Instead, one of the conveyor belts needs to be manually pushed to preset its initial position, and then the electric screw mechanism drives the other conveyor belt to move to the appropriate position. This allows the two conveyor belts of the adjustable-width double-rail docking platform to align with the conveying mechanism of the external equipment, thereby completing the subsequent docking operation. The entire adjustment and docking process is relatively simple. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] This embodiment discloses a width-adjustable dual-rail docking station for transporting circuit boards between two process devices, such as a transfer device and a cooling device, to transport circuit boards from the transfer device to the cooling device.

[0021] Please see Figures 1-7 The width-adjustable dual-rail docking station of this embodiment includes a frame and a conveying module 20. The frame includes a guide structure. Two conveying modules 20 are configured, each mounted on the frame, and each conveying module 20 can independently convey circuit boards.

[0022] Each conveying module 20 includes a conveying drive mechanism, an electric screw mechanism, a locking assembly 30, and two conveyor belts 21. The two conveyor belts 21 are configured to support opposite sides of a circuit board, and all conveyor belts 21 are arranged side-by-side along a first direction. The conveying drive mechanism is configured to drive the two conveyor belts 21 to convey the circuit board along a conveying direction F. Each conveyor belt 21 is slidably connected to a guide structure in a reciprocating motion along the first direction, perpendicular to the conveying direction F. The electric screw mechanism is configured to drive one of the two conveyor belts 21 to reciprocate relative to the guide structure along the first direction. The locking assembly 30 is connected to the guide structure and to the other of the two conveyor belts 21. It should be understood here that the locking assembly 30 is connected to one of the conveyor belts 21, while the electric screw mechanism can drive the other conveyor belt 21.

[0023] When the locking component 30 is locked, the locking component 30 prevents the corresponding conveyor belt 21 from sliding back and forth in the first direction relative to the guide structure. When the locking component 30 is unlocked, the corresponding conveyor belt 21 can move back and forth in the first direction relative to the guide structure.

[0024] During the docking process of the width-adjustable double-track docking platform with the conveying mechanism of other equipment (not shown in the figure), the locking component 30 is first unlocked, and then the corresponding conveyor belt 21 is manually pushed to slide along the guide structure until the conveyor belt 21 is aligned with one side of the external equipment's conveying mechanism. Then, when the locking component 30 is locked, the locking component 30 prevents the conveyor belt 21 from sliding relative to the guide structure, thereby completing the positioning of the conveyor belt 21. Next, the electric screw mechanism is used to drive the other conveyor belt 21 to slide relative to the guide structure until the conveyor belt 21 is aligned with the other side of the external equipment's conveying mechanism. Finally, the two conveyor belts 21 of the width-adjustable double-track docking platform are docked with the two sides of the external equipment's conveying mechanism. Compared with the prior art, in the process of docking the width-adjustable double-rail docking platform with external equipment, it is not necessary to adjust the position of the two conveyor belts 21 by moving the width-adjustable double-rail docking platform. Instead, one of the conveyor belts 21 needs to be manually pushed to preset its initial position. Then, the electric screw mechanism drives the other conveyor belt 21 to move to the appropriate position, so that the two conveyor belts 21 of the width-adjustable double-rail docking platform are aligned with the conveying mechanism of the external equipment, thereby completing the subsequent docking operation. The entire adjustment and docking process is relatively simple.

[0025] In some embodiments, the guide structure includes a guide rod 13, and the conveyor belt 21 is slidably sleeved on the guide rod 13 along its axial direction. Specifically, the frame includes a housing 10, and two vertical plates 12 are provided inside the housing 10. The two ends of the guide rod 13 are fixedly connected to the two vertical plates 12. The conveyor belt 21 is suspended inside the housing 10 by the guide rod 13, which avoids the conveyor belt 21 from contacting the inner wall of the housing 10 during movement and interfering with the movement of the conveyor belt 21.

[0026] In some embodiments, the locking assembly 30 includes a clamp that can be locked onto the guide rod 13 and unlocked from the guide rod 13, the clamp being fastened to the corresponding conveyor belt 21 by fasteners.

[0027] In some embodiments, the clamp includes a fixing seat 31 and a screw 34. The fixing seat 31 is fixed to the conveyor belt 21 by fasteners. The fixing seat 31 has a "C"-shaped wrapping groove 32 and two cantilever arms 33 extending outward from both sides of the opening of the wrapping groove 32. The wrapping groove 32 is inserted into the guide rod 13. One of the two cantilever arms 33 has a mounting hole, and the other has a threaded hole. The screw 34 passes through the mounting hole and is threaded into the threaded hole. When the screw 34 is tightened, the screw 34 forces the two cantilever arms 33 to move in opposite directions, thereby causing the wrapping groove 32 to contract and press tightly against the outer wall of the guide rod 13. The friction between the inner wall of the wrapping groove 32 and the outer wall of the guide rod 13 restricts the relative sliding of the wrapping groove 32 and the guide rod 13, thereby preventing the fixing seat 31 from sliding relative to the guide rod 13, and ultimately preventing the conveyor belt 21 from sliding relative to the guide rod 13. Conversely, when the screw 34 is loosened, the conveyor belt 21 can slide freely relative to the guide rod 13.

[0028] In some embodiments, the electric lead screw mechanism includes a lead screw shaft 22 and a lead screw motor 221. The two ends of the lead screw shaft 22 are rotatably connected to two vertical plates 12 of the frame. The lead screw shaft 22 is threadedly connected to a corresponding transmission belt 21. The lead screw motor 221 is configured to drive the lead screw shaft 22 to rotate in both directions. When the lead screw shaft 22 rotates in both directions, it can drive the corresponding transmission belt 21 to slide back and forth relative to the guide rod 13, thereby adjusting the position of the transmission belt 21.

[0029] In some embodiments, the conveying drive mechanism includes a connecting shaft 23 and a drive motor 231. The two ends of the connecting shaft 23 are rotatably connected to two vertical plates 12 of the frame. The drive motor 231 is located on the outer side of one of the vertical plates 12 and is fixed to the outer wall of the vertical plate 12 or the inner wall of the housing 10 by fasteners. The output shaft of the drive motor 231 is driven by the connecting shaft 23 via a coupling. Both conveyor belts 21 are driven by the connecting shaft 23. When the drive motor 231 drives the connecting shaft 23 to rotate in both directions, the connecting shaft 23 drives the two conveyor belts 21 to convey the circuit board in both directions.

[0030] In some embodiments, the conveyor belt 21 includes a support plate, a conveyor belt, a drive pulley, and multiple driven pulleys. The support plate is threadedly connected to the lead screw shaft 22 and is sleeved on the guide rod 13, allowing it to slide reciprocally relative to the guide rod 13. The drive pulley and multiple driven pulleys are rotatably mounted on the support plate, and the conveyor belt is sleeved on the drive pulley and multiple driven pulleys, supporting the circuit board. The connecting shaft 23 is prismatic in shape, and the shaft of the drive pulley is a hollow tube. The inner shape of the hollow tube is adapted to the shape of the connecting shaft 23. The hollow tube is sleeved on the connecting shaft 23, and when the connecting shaft 23 rotates, it can drive the hollow tube to rotate synchronously. The hollow tube drives the drive pulley to rotate, and the drive pulley drives the conveyor belt to move, thereby conveying the circuit board by the conveyor belt.

[0031] In some embodiments, the width-adjustable dual-track docking station also includes a control unit 11. The conveying module 20 also includes a position sensor 40 for detecting the relative position of the two conveyor belts 21. The position sensor 40 and the electric lead screw mechanism are both electrically connected to the control unit 11. After receiving the detection signal fed back by the position sensor 40, the control unit 11 can control the electric lead screw mechanism to drive the corresponding conveyor belt 21 to slide relative to the guide structure along a first direction.

[0032] In some application scenarios, the operator manually pushes a conveyor belt 21 to move it to a preset position, and then uses a locking assembly 30 to secure the conveyor belt 21 to the guide structure. Then, the control unit 11 controls an electric screw mechanism to drive another conveyor belt 21 towards the already positioned conveyor belt 21, until the position sensor 40 generates a preset detection signal. The control unit 11 then controls the electric screw mechanism to drive the corresponding conveyor belt 21 away from the already positioned conveyor belt 21, until it moves a preset distance and stops. This preset distance is generally the width of the external equipment's conveying mechanism. This scheme allows the adjustment of the distance between the two conveyor belts 21 to be performed automatically according to the width of the external equipment's conveying mechanism.

[0033] In some embodiments, the position sensor 40 is a proximity switch, which includes a sensing head 41 and a sensing plate 42. The sensing head 41 is disposed on one of the two conveyor belts 21, and the sensing plate 42 is disposed on the other of the two conveyor belts 21. When the sensing head 41 contacts the sensing plate 42, the sensing head 41 and / or the sensing plate 42 feed back a detection signal to the control unit 11.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
