Description

Technical Field

[0001] The utility model relates to the technical field of PCB production and processing, and specifically to a double-track cooling buffer machine. Background Art

[0002] In the rapid development of the electronics industry in the 21st century, PCB (printed circuit board) is one of the core components of electronic equipment, and its performance and quality have a vital impact on the reliability, stability and functionality of the entire electronic product. With the continuous improvement of PCB board process requirements, higher challenges have been posed to the accuracy, efficiency and compatibility of processing equipment.

[0003] After the PCB board is electroplated, it is impossible to proceed directly to the next process because the overall temperature of the PCB board can reach 200 degrees or even higher. Natural cooling in the air may cause contamination to the PCB board on the fixture, and it also takes up a lot of space and takes a long time to cool down.

[0004] In order to solve the above problems, the patent document with application number CN201610748768.6 proposes a cooling temporary storage machine, including a board feeding mechanism, a temporary storage mechanism and a board discharging mechanism. The temporary storage mechanism includes a bracket, two second vertical frames installed on the bracket and arranged oppositely, and the second vertical frames include side panels and two vertical frames fixed on the side panels. A plurality of second conveying tracks are installed vertically between the two vertical frames, and each second conveying track is connected to a conveying motor. At least one second fan is installed on the outer side of the plurality of second conveying tracks. Two horizontal plates are fixed between the two side plates, and a third fan is installed on each horizontal plate. The cooling temporary storage machine can not only temporarily store PCB boards, but also cool the temporarily stored PCB boards to improve the cooling efficiency.

[0005] However, in the above-mentioned cooling temporary storage machine, since each second conveying track of its temporary storage mechanism is connected to a conveying motor, a large number of motors and corresponding transmission mechanisms need to be installed inside the temporary storage mechanism, which increases the physical size and manufacturing cost of the entire temporary storage machine; the complex structure also brings higher maintenance costs, because when a motor or transmission component fails, more time and energy are required to diagnose and repair; in addition, since each motor needs to be controlled independently to ensure that the PCB board can move smoothly on each conveying track, this will increase the control difficulty of the temporary storage machine control system and place high requirements on the control system.

[0035] See also Figures 1 to 6 The present embodiment provides a double-track cooling cache machine, including two relatively arranged board inlet lifting mechanisms 1, two relatively arranged cooling cache mechanisms 2 and two relatively arranged board outlet lifting mechanisms 3. The lifting ends of the two board inlet lifting mechanisms 1 are each provided with a board inlet conveying track 11, and the lifting ends of the two board outlet lifting mechanisms 3 are each provided with a board outlet conveying track 31. The two cooling cache mechanisms 2 each include a cache rack 21 and a cooling device 22 arranged outside the cache rack 21. A plurality of cache outlet tracks 211 are arranged in a vertical direction in the cache rack 21. The board inlet end and the board outlet end of each cache outlet track 211 are both connected with a transmission gear 212. The board outlet end of the board inlet conveying track 11 and the board outlet end of the board outlet conveying track 31 are both provided with a gear driving mechanism 12 matched with the transmission gear 212. When a certain board-input lifting mechanism 1 lifts its board-input conveying track 11 to the height of a certain buffer conveying track 211, the gear driving mechanism 12 of the board-input conveying track 11 meshes with the transmission gear 212 at the board-input end of the buffer conveying track 211, thereby driving the buffer conveying track 211 to smoothly receive the PCB board conveyed by the board-input conveying track 11 and temporarily store it. When a certain board-output lifting mechanism 3 lifts its board-output conveying track 31 to the height of a certain buffer conveying track 211, the gear driving mechanism 12 of the board-output conveying track 31 meshes with the transmission gear 212 at the board-output end of the buffer conveying track 211, thereby driving the buffer conveying track 211 to transport the temporarily stored PCB board to the board-output conveying track 31, so that the board-output conveying track 31 can smoothly receive the PCB board and transport it to the next process.

[0036] The above-mentioned double-track cooling buffer machine, by setting a gear driving mechanism 12 at the board outlet end of the board inlet conveying track 11 and the board outlet end of the board outlet conveying track 31, and setting a transmission gear 212 at the board inlet end and the board outlet end of each cache conveying track 211, adopting the gear driving mechanism 12 and the transmission gear 212 to realize the board inlet and board outlet of the cooling cache mechanism 2, compared with the method of equipping each cache conveying track 211 with a motor, it greatly simplifies the structure, reduces the manufacturing cost, and also reduces the control difficulty, and improves the stability and reliability of the overall system; by setting a cooling device 22 on the outside of the cache rack 21, it is possible to achieve rapid and uniform cooling of the temporarily stored PCB boards, thereby improving the cooling efficiency; by cooperating with the board inlet lifting mechanism 1, the board outlet lifting mechanism 3 and the gear driving mechanism 12, the double-track cooling buffer machine can realize automatic board inlet, temporary storage, cooling and board outlet of the PCB boards, thereby greatly improving the production efficiency, reducing the error rate of manual operation, and at the same time ensuring that the PCB boards are processed in a first-in-first-out order to maintain the smoothness and efficiency of the production line.

[0037] See also Figure 3 , Figure 4In one embodiment, the board-feeding conveying track 11 includes a first fixed rail 111 and a first movable rail 112 that are arranged opposite to each other, and the first fixed rail 111 can be close to or away from the first movable rail 112. The board-feeding conveying track 11 can adjust the distance between the first fixed rail 111 and the first movable rail 112 according to the size of the PCB board through the first fixed rail 111 and the first movable rail 112 arranged as above, so that the board-feeding conveying track 11 can be suitable for PCB boards of different widths, which greatly improves the compatibility and flexibility of the equipment, enables one equipment to handle carriers of various specifications, and reduces the production cost and the complexity of equipment maintenance.

[0038] Among them, the first fixed rail 111 and the first movable rail 112 are both provided with a first conveyor belt 1111 on the opposite side, and the first conveyor belt 1111 is connected to the first belt drive motor 1113 through the first transmission component 1112. After the first belt drive motor 1113 is started, the first transmission component 1112 drives the first conveyor belt 1111 on the first fixed rail 111 and the first movable rail 112 to rotate smoothly and continuously, and then the first conveyor belt 1111 is used to efficiently convey the carrier, thereby improving the working efficiency of the equipment. The utility model adopts the first conveyor belt 1111 as a conveying component because its maintenance and replacement are relatively simple and convenient; when the first conveyor belt 1111 is worn or fails, the operator can quickly replace or repair it to ensure the normal operation of the equipment.

[0039] See also Figure 5 , Figure 6 In one embodiment, the board delivery conveying track 31 includes a second fixed rail 311 and a second movable rail 312 that are arranged opposite to each other, and the second fixed rail 311 can be close to or away from the second movable rail 312. The board delivery conveying track 31 can adjust the distance between the second fixed rail 311 and the second movable rail 312 according to the size of the PCB board through the second fixed rail 311 and the second movable rail 312 arranged as above, so that the board delivery conveying track 31 can be suitable for PCB boards of different widths, which greatly improves the compatibility and flexibility of the equipment, enables one equipment to handle carriers of various specifications, and reduces the production cost and the complexity of equipment maintenance.

[0040] The second fixed rail 311 and the second movable rail 312 are both provided with a second conveyor belt 3111 on the opposite side. The second conveyor belt 3111 is connected to the second belt drive motor 3113 through the second transmission assembly 3112. After the second belt drive motor 3113 is started, the second conveyor belt 3111 on the second fixed rail 311 and the second movable rail 312 is driven to rotate smoothly and continuously through the second transmission assembly 3112, thereby realizing efficient conveying of the carrier through the second conveyor belt 3111, thereby improving the working efficiency of the equipment. The utility model adopts the second conveyor belt 3111 as the conveying component because its maintenance and replacement are relatively simple and convenient; when the second conveyor belt 3111 is worn or fails, the operator can quickly replace or repair it to ensure the normal operation of the equipment.

[0041] See also Figure 2 In one embodiment, the cache rack 21 includes a fixed vertical frame 213 and a movable vertical frame 214 that are relatively arranged. The movable vertical frame 214 can be close to or away from the fixed vertical frame 213. A plurality of cache conveying tracks 211 are arranged vertically between the fixed vertical frame 213 and the movable vertical frame 214. The cache rack 21 can adjust the distance between the fixed vertical frame 213 and the movable vertical frame 214 according to the size of the PCB board through the fixed vertical frame 213 and the movable vertical frame 214 arranged as above, so that the cache rack 21 can be applied to PCB boards of different widths, which greatly improves the compatibility and flexibility of the equipment, enables one equipment to handle carriers of various specifications, and reduces the production cost and the complexity of equipment maintenance.

[0042] See also Figure 2 In one embodiment, the cooling device 22 includes an air guide shell 221 fixed on the outside of the fixed vertical frame 213 and a plurality of heat dissipation fans 222 arranged in an array in the air guide shell 221. The air guide shell 221 is provided with an air outlet on a side close to the fixed vertical frame 213, and the heat dissipation fan 222 blows air toward the air outlet. A ventilation interface 2211 is provided on the air guide shell 221. The ventilation interface 2211 is connected to the cold air supply port of the cooling machine through a pipeline, so as to continuously supply cold air into the air guide shell 221, and then the cold air is blown through the air outlet to the PCB board temporarily stored in the cache rack 21 by the heat dissipation fan 222, thereby achieving the purpose of rapid cooling.

[0043] See also Figure 4 , Figure 6In one embodiment, the gear drive mechanism 12 includes a telescopic cylinder 121, a motor gear fixing plate 122, a gear drive motor 123, and a driving gear 124. The gear drive motor 123 is arranged on one side of the motor gear fixing plate 122, and the driving gear 124 is arranged on the other side of the motor gear fixing plate 122. The driving shaft of the gear drive motor 123 passes through the motor gear fixing plate 122 and is connected to the driving gear 124. The telescopic end of the telescopic cylinder 121 is connected to the motor gear fixing plate 122 to drive the driving gear 124 to approach or move away from the corresponding transmission gear 212 through the motor gear fixing plate 122. When the driving gear 124 is meshed and connected with the transmission gear 212 of a certain cache conveying track 211, the gear drive motor 123 is started to provide transmission power for the cache conveying track 211. In addition, since the driving gear 124 is meshed and connected with the transmission gear 212 of a certain cache conveying rail 211, if the board entry lifting mechanism 1 / board exit lifting mechanism 3 directly drives the driving gear 124 to move up and down, it will cause wear to the driving gear 124 or the transmission gear 212. Therefore, when lifting, it is necessary to first drive the driving gear 124 away from the current transmission gear 212 through the telescopic cylinder 121, and then lift it to the height of another cache conveying rail 211, and then drive the driving gear 124 to approach the transmission gear 212 of the cache conveying rail 211 through the telescopic cylinder 121 until it meshes with it, so that the gear drive motor 123 can provide transmission power for the cache conveying rail 211.

[0044] See also Figure 7 , Figure 8 In one embodiment, the double-track cooling cache machine also includes a hood 4, which covers two board-input lifting mechanisms 1, two cooling cache mechanisms 2, and two board-output lifting mechanisms 3. The hood 4 provides physical protection for the entire device, prevents the outside world from directly touching and interfering with the device, reduces the risk of accidental start or stop of the device, and improves the safety of operation. In addition, the hood 4 can also effectively prevent the cold or noise generated during the cooling process from leaking out, reduce the impact on the surrounding environment and personnel, and improve the comfort of the working environment. Among them, the hood 4 is provided with a board inlet 41 on one side close to the two board-input lifting mechanisms 1, and the hood 4 is provided with a board outlet 42 on one side close to the two board-output lifting mechanisms 3, so that the entry and exit of the PCB board is more orderly and convenient.
