Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, specifically to a board separating machine and its transfer and pressing device for automatically separating circuit boards. Background Technology

[0002] The existing circuit board depaneling machine includes a transfer device, a depaneling device, a carrying device, a clamping device, and a first drive unit. The transfer device is a robotic arm that can move between the previous station and the loading / unloading station. Driven by the first drive unit, the carrying device and the clamping device can move back and forth in a straight line between the loading / unloading station and the depaneling station. In addition, the clamping device includes a second drive unit, a pressing drive unit, and a pressure plate. Driven by the second drive unit, the pressure plate and the pressing drive unit can move relative to the carrying device in the aforementioned straight line. The depaneling device is set on the depaneling station. The pressure plate has processing through holes on its upper and lower sides. Driven by the pressing drive unit, the pressure plate can move up and down between the pressing position and the releasing position.

[0003] When the depaneling machine is working, the robotic arm first moves the circuit board from the previous workstation to the carrier of the support device located at the loading / unloading station. Then, the first drive unit drives the carrier device to move to the depaneling station, while the second drive unit drives the pressure plate to move horizontally to the depaneling station and above the carrier of the support device. Then, the pressing drive unit drives the pressure plate to descend from the released position to the pressing position to press the circuit board firmly. Subsequently, the depaneling device mills the circuit board along the depaneling through holes of the pressure plate. After the depaneling process is completed, the first drive unit drives the carrier device to move to the loading / unloading station. During this process, the pressing drive unit first drives the pressure plate to rise from the pressing position to the released position to release the circuit board, and then the second drive unit drives the pressure plate to move away from above the carrier to avoid obstructing the robotic arm from picking up the circuit board at the loading / unloading station.

[0004] The existing circuit board depaneling machine has the problem that the depaneling machine device is numerous and complex, and the equipment cost is high. Utility Model Content

[0005] The primary objective of this invention is to provide a transfer and pressing device that reduces the number of components in a PCB depaneling machine, thereby lowering costs.

[0006] The second objective of this invention is to provide a depaneling machine that reduces the number of devices required to lower costs.

[0007] The first objective of this utility model is to provide a transfer and pressing device, which includes a translation drive unit and a pressing assembly. The pressing assembly includes a lifting drive unit and a pressure plate. The translation drive unit drives the pressing assembly to translate along a first direction, and the lifting drive unit drives the pressure plate to rise and fall. The pressure plate is provided with a through hole that penetrates both sides of its thickness. The pressure plate includes a lower side. The pressing assembly includes a negative pressure suction head, which is connected to the lower side. An airflow channel is provided inside the pressure plate, and the first airflow port of the airflow channel is located on the lower side. The negative pressure suction head is connected to the first airflow port.

[0008] As can be seen from the above solution, since the clamping component itself needs to be positioned above the circuit board, move horizontally between different positions, and move vertically between the clamping and releasing positions, it possesses the necessary degrees of freedom for transferring the circuit board. Therefore, this invention considers improving the clamping component into one capable of transferring the circuit board. Specifically, an airflow channel is provided within the pressure plate, and a negative pressure suction head is provided on the lower side of the pressure plate. After the airflow channel is connected to the air pressure generating device, the negative pressure suction head can adsorb the circuit board from above. In this way, the clamping component can both adsorb and remove the circuit board from the loading station and transfer it to the separating station, and simultaneously clamp the circuit board without releasing it while lowering it to place it onto the separating station carrier. This invention not only replaces the original clamping and transferring devices with a clamping device, reducing the number of devices and lowering equipment costs, but also simplifies processing actions and accelerates the production pace.

[0009] A further solution is to use an elastic material for the negative pressure suction head, with the suction head protruding downwards.

[0010] As can be seen from the above, this setup also allows the negative pressure suction head to be used as a buffer protection structure when pressing down on the circuit board, preventing hard contact and damage to the circuit board, thus improving the yield rate.

[0011] A further approach is to use multiple negative pressure suction heads, arranged in an array on the lower side.

[0012] As can be seen from the above, this setting not only improves the success rate and reliability of the clamping device, but also provides more reasonable buffer protection for the circuit board from multiple positions.

[0013] A further approach is to machine through holes that extend in a straight line on the pressure plate, with two or more through holes arranged in an array between adjacent through holes.

[0014] As can be seen from the above, this setting ensures that the circuit board can be pressed on both sides of the board cutting line, ensuring that the cutting action is stable and effective, and improving the yield.

[0015] A further option is to include a second airflow port in the airflow channel, which is located at the edge of the pressure plate.

[0016] As can be seen from the above, under this setting, an airflow channel can be formed on the pressure plate by drilling along the extension direction of the pressure plate.

[0017] A further embodiment is that the pressure plate includes a first edge in a first direction, and a second air outlet is disposed at the first edge of the pressure plate.

[0018] As can be seen from the above, the second air outlet, which is connected to the air pressure generating device pipeline, is located at the first edge along the first direction of the pressure plate translation, avoiding interference with the lifting drive units on both sides of the pressure plate, making the equipment structure more reasonable.

[0019] A further solution is to detachably connect the pressure plate to the output end of the lifting drive unit.

[0020] As can be seen from the above, this setting allows the pressure plate to be disassembled and replaced, enabling it to complete the separation work for different board types and different cutting requirements.

[0021] A further embodiment includes a locking lever in the clamping assembly. The locking lever has a locking protrusion located in its circumferential position. The locking lever is rotatably connected to one of the pressure plate and the output end. The other of the pressure plate and the output end is provided with a socket, which includes an unlocking hole located in its circumferential position. The locking lever is inserted into the socket, and the locking protrusion protrudes out of the socket. When the locking protrusion is misaligned with the unlocking hole, the locking protrusion restricts the other of the pressure plate and the output end. When the locking protrusion is aligned with the unlocking hole, the locking protrusion releases the restriction on the other of the pressure plate and the output end.

[0022] As can be seen from the above, compared with the transmission method of bolts and nuts, this setting enables quick locking and unlocking of the pressure plate, improving the efficiency of pressure plate assembly and disassembly.

[0023] A further option is that the lifting drive unit includes a motor.

[0024] As can be seen from the above, compared to cylinders, the lifting drive unit uses a motor to complete the more precise lifting stroke requirements needed when used as a transfer device, and can better control the clamping force on the circuit board to protect it.

[0025] The second objective of this utility model is a board separating machine, which includes a board separating device, a conveying device, and a pressing device. The conveying device can grab the board and move it between the loading station and the board separating station. The pressing device can be moved to the board separating station. The board separating device is set at the board separating station. The above-mentioned conveying and pressing device is used as the conveying device and the pressing device.

[0034] Examples of transfer and pressing devices, and examples of PCB depaneling machines.

[0035] See Figure 1 and Figure 2 The transfer and pressing device in this embodiment includes a translation drive unit 1 and a pressing assembly. The pressing assembly includes a lifting drive unit 2, a pressure plate 3, a negative pressure suction head 4, and a locking rod 5.

[0036] The translation drive unit 1 includes two sets of linear modules. Each linear module includes a slide rail extending along a first direction (x-axis direction in the figure) and a slider connected to the slide rail. The two sets of linear modules are arranged at intervals along a second direction perpendicular to the first direction (y-axis direction in the figure). There are two lifting drive units 2. Each lifting drive unit 2 is fixedly connected to a slider. In this way, each of the two sets of linear modules drives one lifting drive unit 2 to translate along the first direction.

[0037] The lifting drive unit 2 includes a motor, a lead screw assembly, a slide assembly, and an output end 21 connected in sequence. The output end 21 is a connecting plate. The lead screw assembly includes a lead screw and a lead screw nut. The slide assembly includes a sliding seat and a slide. The output shaft of the motor extends vertically downward and rotates coaxially with the lead screw. The lead screw nut, the slide, and the output end 21 are relatively fixed and lift and lower synchronously. The slide and the sliding seat slide together vertically.

[0038] Thus, when the motor is working, it can drive the output end 21 to move up, down, and horizontally. The pressure plate 3 is fixedly connected to the two output ends 21 on both sides by the locking rod 5. The pressure plate 3 can move up and down with the two output ends 21 and can also move horizontally with the two output ends 21. This setting realizes the horizontal and vertical movement of the pressure plate 3, which meets the motion design requirements for the pressure plate 3 to transfer the circuit board.

[0039] See Figure 3 The pressure plate 3 is provided with processing through holes 30 extending through both sides of its thickness. In this embodiment, the processing through holes 30 are elongated holes extending along the first direction, and there are three processing through holes 30, which are arranged at intervals along the second direction. An airflow channel 300 is provided inside the pressure plate 3. The pressure plate 3 has a first edge 311 and a second edge 312 opposite to each other in the first direction. The airflow channel 300 passes through the first edge 311 and the second edge 312 in a straight line along the first direction. Two airflow channels 300 are provided between any two adjacent processing through holes 30, and a total of four airflow channels 300 are arranged at intervals along the second direction.

[0040] The pressure plate 3 has a downward-facing lower side 39. A hole is drilled upward on the lower side 39 to open the first airflow port 309 of the airflow channel 300. A negative pressure suction head 4 is installed at each first airflow port 309. The negative pressure suction head 4 is connected to the first airflow port 309. Each airflow channel 300 includes four first airflow ports 309. A total of sixteen first airflow ports 309 are arranged in a rectangular array on the lower side 39. That is, sixteen negative pressure suction heads 4 are arranged in a rectangular array on the lower side 39 along the extension surface of the pressure plate 3.

[0041] In addition, in order to set up the airflow channel 300, holes are drilled along the first direction to form openings at both the first edge 311 and the second edge 312. The opening at the second edge 312 is sealed with a sealing screw 62, while the opening at the first edge 311 is fitted with a pipe connector 61 to serve as the second airflow port 308 of the airflow channel 300 in this utility model. The pipe of the air pressure generating device is connected to the pipe connector 61, thereby generating negative pressure at the first airflow port 309 to adsorb the circuit board.

[0042] Additionally, see Figure 4 The negative pressure suction head 4 is made of an elastic material such as rubber or silicone, and protrudes downwards from the lower side 39. With this configuration, the negative pressure suction head 4 serves as a buffer protection structure when pressing down on the circuit board 9, avoiding hard contact that could damage the circuit board 9 and improving the yield rate.

[0043] See Figure 5 and Figure 6The locking lever 5 includes a lever body 50, and the locking lever 5 also includes a locking protrusion 51 located at the circumferential position of the first axial end of the lever body 50. The locking protrusion 51 is a column extending radially along the lever body 50 and protruding from the outer circumferential surface of the lever body 50. The locking lever 5 also includes a head 52 located at the second axial end of the lever body 50. The outer diameter of the head 52 is larger than the outer diameter of the lever body 50, and the axial end face of the head 52 facing away from the locking protrusion 51 is provided with an internal hexagonal hole.

[0044] The output end 21 has a socket 210 that extends vertically through its own plate. The socket 210 includes two unlocking holes 211 located in its circumferential position. The two unlocking holes 211 extend radially along the socket 210 and are located on opposite sides of the axis of the socket 210, so that the axial projection of the socket 210 forms a straight line. In addition, the plate of the output end 21 also includes a baffle 219 located in the circumferential position of the socket 210 and outside the unlocking holes 211. In the axial projection of the socket 210, the two baffles 219 are respectively located on opposite sides of the socket 210.

[0045] Combined Figure 7 The locking rod 5 is rotatably connected to the pressure plate 3, and its head 52 is axially positioned with the pressure plate 3 along the locking rod 5. The locking rod 5 is inserted into the insertion hole 210, and the locking protrusion 51 protrudes out of the insertion hole 210. Figure 7 As shown in state diagram a, when the locking protrusion 51 is opposite to the unlocking hole 211, the locking protrusion 51 releases the restriction on the output end 21, and at this time the pressure plate 3 can be axially separated and disassembled relative to the output end 21. Figure 7 As shown in state diagram b, when the locking protrusion 51 is misaligned with the unlocking hole 211, the locking protrusion 51 restricts the baffle 219 of the output end 21 along the axial direction of the locking rod 5. At this time, the pressure plate 3 and the output end 21 are clamped between the head 51 and the locking protrusion 51 and fixed to each other. Compared with the transmission means of bolts and nuts, this setting allows for quick locking and unlocking of the pressure plate 3, improving the efficiency of pressure plate 3 assembly and disassembly.

[0046] See Figure 8The PCB separator of this embodiment includes a separator 83, a transfer device, and a clamping device. Specifically, the separator 83 is a moving module with planar and vertical translation functions and a milling cutter mounted at the moving end. The transfer device can grasp the circuit board 9 and transfer it between the loading station 801 and the separator 802. The clamping device can move to the separator 802, and the separator 83 is located at the separator 802. In this embodiment, the transfer and clamping device serves as both the transfer device and the clamping device. Because this invention features an airflow channel 300 within the pressure plate 3 and a negative pressure suction head 4 on the lower side 39 of the pressure plate 3, the airflow channel 300, when connected to a pressure generating device, allows the negative pressure suction head 4 to adsorb the circuit board 9 from above. Thus, the clamping assembly can both remove the circuit board 9 from the loading station 801 and transfer it to the separating station 802, and simultaneously clamp the circuit board 9 without releasing it while lowering it onto the carrier at the separating station 802. Subsequently, the milling cutter of the separating device 83 can pass through the machining through-hole 30 on the pressure plate 3 from top to bottom to cut the circuit board 9, completing the separating process. This invention not only replaces the original clamping and conveying devices with a clamping device, reducing the number of devices and lowering equipment costs, but also simplifies processing actions and accelerates production.

[0047] In other embodiments, the locking lever is rotatably connected to the output end, and the pressure plate is provided with a socket.

[0048] In other embodiments, the pressure plate and the output end are detachably connected by bolts and screw holes.

[0049] In other embodiments, the translation drive unit may also be a linear motor or a cylinder.

[0050] In other embodiments, the lifting drive unit may be a cylinder.

[0051] In other embodiments, the second air outlet is located on the upper side of the pressure plate.

[0052] In other embodiments, blind holes can be drilled in the pressure plate to form airflow channels, so that the other end of the blind hole is self-sealed and does not need to be plugged.

[0053] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
