Description

Technical Field

[0001] This utility model relates to the field of circuit board depaneling technology, and in particular to a depaneling device for circuit board production. Background Technology

[0002] In the production process of printed circuit boards (PCBs), most manufacturing plants typically produce multiple PCBs from a single PCB to improve production efficiency. This production method significantly increases PCB production efficiency. After the entire PCB is produced, it is sent to a slitting workshop where a slitting device cuts the PCB into multiple PCBs of a specified size. However, existing slitting devices typically require manual cutting by workers, resulting in low slitting efficiency, safety hazards due to worker contact with the cutting machine, and low automation, thus reducing the overall PCB slitting efficiency.

[0003] The prior art (authorization announcement number: CN223157317U) discloses a PCB separation device for circuit board production. It uses components such as T-shaped frame, L-shaped frame, bolts and pressure blocks to work together. The movement of the bolts drives the movement of the L-shaped frame, which in turn drives the movement of the pressure block to cooperate with the protrusion to limit the circuit board. This can effectively prevent the circuit board from shaking when the mechanical movement generates vibration, which would cause deviation in the PCB separation.

[0004] In this application, when picking up and placing circuit boards on the working surface, it is necessary to rotate the bolts in multiple locking mechanisms to rotate the pressure block and separate it from the circuit board. The operation process requires a lot of manual time, which leads to low efficiency in cutting circuit boards.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 5 A board separation device for circuit board production is shown, comprising: a housing 100, a base plate 110 for positioning fixed at the bottom of the housing 100, a processing groove 120 for storing circuit boards on the upper surface of the housing 100, and two sets of positioning components 200 for pressing and stabilizing the circuit boards in the processing groove 120 at the top of the housing 100 near the front and rear edges. The positioning assembly 200 includes two sets of outer cylinders 230 fixed to the top of the outer casing 100. Each set of outer cylinders 230 has an inner rod 220 extending into the outer casing 100. The top of the inner rod 220 is bolted to a long straight bar 210. The bottom of the long straight bar 210 is located on one side of the outer cylinder 230 and has a telescopic rod 250. The bottom of the telescopic rod 250 is fixed to a pressure plate 280 that can press the circuit board and stabilize it in the processing groove 120. The curved outer wall of the outer cylinder 230 has a guide ring groove 231. The outer wall of the telescopic rod 250 is fixed to a ball head rod 290 that slides in the guide ring groove 231. The outer wall of the inner rod 220 is located inside the outer casing 100 and has a toothed ring 240. The outer casing 100 has a rack 260 that meshes with the two sets of toothed rings 240 and can drive the inner rod 220 to rotate. The positioning assembly 200 also includes an L-shaped bar 270 disposed on the housing 100 and located at the bottom of the rack 260. The bottom of the L-shaped bar 270 is fixed to the housing 100 by an L-shaped piece, which is connected to the housing 100 by bolts.

[0021] It is worth mentioning that the telescopic rod 250 is composed of a telescopic cylinder 252 and an inner shaft 251, which are sleeved together and can slide, while the ball head rod 290 is fixed to the outer wall of the telescopic cylinder 252; Meanwhile, a notch is provided at the position corresponding to the L-shaped fish handle 261, and the size of the notch corresponds to the long straight groove 180.

[0022] The circuit board to be cut is placed in the processing groove 120. Then, the operator pushes the handle 261, causing the rack 260 to move along the long straight groove 180. The teeth of the rack 260 simultaneously engage with two sets of toothed rings 240, driving the inner rod 220 to rotate in the outer cylinder 230. The inner rod 220 drives the long straight bar 210 at the top to rotate synchronously, forcing the ball head rod 290 fixed to the outer wall of the telescopic rod 250 to slide along the guide ring groove 231 on the surface of the outer cylinder 230. Due to the helical trajectory constraint of the guide ring groove 231, the sliding of the ball head rod 290 is converted into the vertical displacement of the telescopic rod 250, which drives the pressure plate 280 to press down into the processing groove 120, and stably clamps the circuit board on the bottom surface of the processing groove 120. At this time, L-bar 270 forms a bottom support for rack 260 to prevent it from deforming under force. After the laser cutting machine finishes the board splitting operation, pull the handle 261 in the opposite direction. Rack 260 moves backward and drives inner rod 220 to reverse. Through the cooperation of guide ring groove 231 and ball head rod 290, telescopic rod 250 is raised, and pressure plate 280 is separated from the surface of circuit board. The split circuit board can then be taken out. It should be noted that the bottom of the rack 260 is fixed with a handle 261 extending to the front side of the housing 100. A long straight groove 180 is provided at the position where the front surface of the housing 100 contacts the handle 261. Brush strips 181 are fixed on the upper and lower inner walls of the long straight groove 180.

[0023] The brush strip 181 seals the long straight groove 180, preventing the intrusion of dust and other debris. At the same time, a rubber sleeve is provided at the contact point between the outer wall of the handle 261 and the long straight groove 180. The rubber sleeve is misaligned with the brush strip 181, which increases the static friction of the handle 261 and prevents the handle 261 from moving automatically.

[0024] Please refer to this carefully. Figure 2 and Figure 3 A through hole 190 is provided at the position where the top of the outer shell 100 contacts the inner rod 220. A support piece 221 is fixed to the inner wall of the outer shell 100 and abuts against the bottom of the inner rod 220. The top of the support piece 221 is connected to the bottom of the inner rod 220 by a bearing.

[0025] The support plate 221 provides stable support to the bottom of the inner rod 220, ensuring that the inner rod 220 rotates smoothly in the through hole 190.

[0026] Please refer to this carefully. Figure 1 , Figure 4 and Figure 5The lower inner wall of the processing groove 120 is provided with two sets of lifting plates 130. An electric push rod 140 is installed inside the outer shell 100 at the top of the base plate 110. A connecting rod 150 is fixed to the telescopic end of the electric push rod 140. Two sets of positioning shafts 170 are fixedly sleeved at both ends of the connecting rod 150. The top of the positioning shaft 170 is connected to the lower surface of the lifting plate 130 and can lift the lifting plate 130 to a higher position. A positioning cylinder 160 is fixed to the inner wall of the base plate 110 and sleeved on the outer wall of the positioning shaft 170. The positioning shaft 170 can be raised and lowered linearly along the axis of the positioning cylinder 160.

[0027] After the circuit board is cut, the electric push rod 140 is controlled to extend its conveying part quickly, which in turn pushes the connecting rod 150 to rise synchronously. The positioning shaft 170 also rises accordingly, which can drag the lifting plate 130 to rise, so that the cut circuit board is raised, creating a gap between the bottom and the upper surface of the outer casing 100, making it easy for personnel to hold and remove the circuit board.

[0028] Please refer to this carefully. Figure 1 and Figure 5 The machining groove 120 has four sets of positioning plates near the inside corner, and the size of the positioning plates is adapted to the holes opened near the outside corner on the circuit board.

[0029] When the circuit board is placed inside the processing slot 120, the hole fits into the outer wall of the positioning piece, ensuring that the circuit board is stable and ready for cutting.

[0030] Please refer to this carefully. Figure 1 Bolt holes are provided on the upper surface of the base plate 110 at the external corner.

[0031] Simply screw the bolts into the bolt holes until the connection with the external platform is established.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
