Description

Technical Field

[0001] The invention belongs to the technical field of PCB milling cutter cleaning equipment and relates to a continuous cleaning device for PCB milling cutter production. Background Art

[0002] The milling cutter used for PCB is also called a milling cutter. It is used in the post-process of PCB (or pressing and catching the outer frame). The main purpose is to use this cutter to cut the manufactured circuit board into individual PCS or SPNL and then ship it to the customer. That is the product size that the customer ultimately requires. This cutter is mainly used for cutting. The blade and force direction are horizontal, similar to a drill needle, but the force and cutting direction of the drill needle are at the drill tip. There are two types of milling cutters: fishtail type and drill tip type. The special design focuses on the service life of the milling cutter and the chip removal effect. It is characterized by a large chip removal groove, which makes chip removal smooth, heat generation is low, and there are fewer stains on the hole wall during drilling;

[0003] After the PCB milling cutter is produced, it needs to be cleaned. The existing cleaning equipment generally inserts the PCB milling cutter on a placement tray, and then puts the placement tray into an ultrasonic cleaning tank for cleaning. The ultrasonic cleaning effect is good and batch cleaning can be performed. However, the handle of the PCB milling cutter inserted into the placement tray is blocked by the placement tray, and the cleaning effect is poor.

[0004] Based on this, we designed a continuous cleaning device for PCB milling cutter production. Summary of the invention

[0005] The purpose of the present invention is to address the above problems in the existing technology and to propose a continuous cleaning device for PCB milling cutter production. The technical problem to be solved by the device is: how to improve the cleaning effect of the cleaning device on the PCB milling cutter.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A continuous cleaning device for PCB milling cutter production comprises an ultrasonic cleaning tank and a placement plate, wherein the ultrasonic cleaning tank is filled with cleaning liquid, two rotating rollers are rotatably arranged in the ultrasonic cleaning tank, a conveyor belt is installed between the two rotating rollers, and a driving motor for driving one of the rotating rollers to rotate is installed on the outer side of the ultrasonic cleaning tank, the placement plate is placed on the conveyor belt, a quick-release handle is provided above the placement plate, and a plurality of jacks for inserting PCB milling cutters are provided on the placement plate, a lifting mechanism for lifting the PCB milling cutter is provided on the conveyor belt, a frame is fixed at the upper end of the ultrasonic cleaning tank, two rotating shafts are rotatably arranged on the frame, a conveyor belt is installed between the two rotating shafts, a plurality of first fixed plates are fixed on the conveyor belt, and a limiting hole is provided on the first fixed plate, and a synchronous transmission mechanism is provided between the conveyor belt and the quick-release handle.

[0008] The working principle of the present invention is as follows: after the production of the PCB milling cutter is completed, the PCB milling cutter can be inserted into the insertion hole of the placement disk, and then the PCB milling cutter is transferred through the placement disk. When the PCB milling cutter is cleaned, the operator can install the quick-release handle on the placement disk, and then place the placement disk on the conveyor belt. At this time, the PCB milling cutter is completely immersed in the cleaning liquid. Under the action of the ultrasonic cleaning tank, the cutter head part of the PCB milling cutter is fully cleaned. With the transfer of the conveyor belt, the placement disk moves to the bottom of the conveyor belt and drives the conveyor belt to run through the synchronous transmission mechanism. At this time, the insertion hole on the placement disk is just aligned with the upper limit hole of the first fixed plate. Under the action of the lifting mechanism, the PCB milling cutter is lifted upward, and the head of the PCB milling cutter is inserted into the limiting hole above it. At the same time, the handle of the PCB milling cutter is moved out of the socket. At this time, under the action of the ultrasonic cleaning tank, the handle part is fully cleaned, and then the lifting mechanism puts down the PCB milling cutter, so that the PCB milling cutter is reinserted into the socket. At this time, another operator can take out the placement plate through the quick release handle at the other end of the ultrasonic cleaning tank, and remove the quick release handle again for reuse, which not only realizes continuous cleaning, but also can clean all parts of the PCB milling cutter, thereby improving the cleaning effect of the PCB milling cutter.

[0009] The two ends of the ultrasonic cleaning pool are respectively connected with a water inlet pipe and a water outlet pipe.

[0010] With the above structure, during use, the cleaning liquid is continuously input through the water inlet pipe and discharged through the water outlet pipe, so as to keep the cleaning liquid inside the ultrasonic cleaning tank continuously effective.

[0011] The lifting mechanism includes a plurality of second fixed plates, which are fixed on the outside of the conveyor belt and are evenly spaced. The second fixed plates are provided with a plurality of through holes, and the conveyor belt is provided with a plurality of circular holes aligned with the through holes. A push rod is slidably arranged in the through hole, a shoulder is fixed on the push rod, and a return spring is sleeved on the push rod, and the two ends of the return spring are respectively against the inner wall of the through hole and the shoulder. A trapezoidal support block is fixed inside the ultrasonic cleaning tank, and the upper surface of the trapezoidal support block is in contact with the inner surface of the conveyor belt.

[0012] With the above structure, as the conveyor belt moves, when the bottom of the push rod contacts the trapezoidal support block, it is squeezed by the side wall of one side of the trapezoidal support block, and the push rod is lifted upward and compresses the reset spring. At this time, the upper end of the push rod will be inserted into the bottom of the socket and squeeze the PCB milling cutter inside it upward, so that the cutter head part of the PCB milling cutter is inserted into the limiting hole above it, and then the push rod contacts the upper surface of the trapezoidal support block, which can keep the PCB milling cutter from falling and fully rinse the handle part. After that, the bottom of the push rod contacts the other side wall of the trapezoidal support block. At this time, under the action of the reset spring, the push rod gradually descends, and the PCB milling cutter then descends and is reinserted into the socket.

[0013] An anti-skid pad is fixed to the upper end of the push rod.

[0014] With the above structure, the anti-skid pad can prevent the bottom of the lifted PCB milling cutter from shaking, thereby ensuring that the PCB milling cutter can be reinserted into the socket, preventing the PCB milling cutter from falling during the cleaning process, and improving the operating stability of the device.

[0015] The placement plate is provided with a plurality of small holes, and the upper ends of the small holes are connected with the corresponding insertion holes, and a guiding inclined surface is provided between the small holes and the insertion holes, and a first chamfer is provided at the upper opening of the insertion hole, and two symmetrically distributed card strips and two symmetrically distributed support strips are provided at the bottom of the placement plate, and the support strips and the card strips are alternately distributed, and two symmetrically distributed limit blocks are fixed above the second fixed plate.

[0016] With the above structure, when in use, when the operator places the placement tray on the conveyor belt, the two card strips can be respectively clamped on the outer sides of the two second fixed plates at the corresponding positions, and at the same time, the two sides of the placement tray can be respectively against the limit blocks. At this time, the placement tray can be stably placed on the conveyor belt without sliding, and the small hole can be aligned with the ejector rod. When the PCB milling cutter is inserted into the socket, the bottom of the PCB milling cutter will be against the guide inclined surface and will not fall downward, and the iron filings cleaned from the PCB milling cutter can flow downward along the guide inclined surface without accumulation. Moreover, under the action of the first chamfer, when the PCB milling cutter descends, it can be inserted into the socket more accurately, preventing the PCB milling cutter from tilting and causing the device to get stuck, or causing damage to the PCB milling cutter.

[0017] The quick-release handle includes a first cross bar and a second cross bar, and an elastic sheet is fixed between the first cross bar and the second cross bar, and connecting plates are fixed to the ends of the first cross bar and the second cross bar, and a conical locking block is fixed to the inner side of the connecting plate, and a locking hole matching the conical locking block is provided at the side end of the placement plate, a notch is provided at one end of the first cross bar close to the second cross bar, a first sliding hole is provided at one end of the second cross bar close to the first cross bar, and a second sliding hole is provided on the upper side of the first sliding hole, an insertion rod is slidably arranged in the first sliding hole, and a push block is fixed on the upper surface of the insertion rod, the push block is located inside the second sliding hole, a first magnetic block is embedded at the bottom of the first sliding hole, and a second magnetic block is fixed to one end of the insertion rod away from the first cross bar, and a soft sleeve is provided on the outer side of the second cross bar.

[0018] With the above structure, when the operator installs the quick-release handle, the push block can be slid in the direction away from the first cross bar. At this time, the insertion rod is pulled out of the recess. At this time, the first cross bar and the second cross bar are only connected by the elastic sheet, which can bend, so that the connecting plates on both sides are separated to both ends. Then the conical locking block is aligned with the locking hole, and the push block is released. Under the mutual repulsive force of the first magnetic block and the second magnetic block, the insertion rod is reinserted into the recess. At this time, the bending capacity between the first cross bar and the second cross bar is limited. At this time, the operator can hold the soft sleeve on the second cross bar to place the placement plate into the ultrasonic cleaning tank. Conversely, the quick-release handle can be disassembled for easy reuse.

[0019] Limiting rings are arranged at both ends of the rotating shaft, and a second chamfer is arranged at the opening of the limiting hole.

[0020] With the above structure, the limit ring can limit the conveyor belt to prevent the conveyor belt from deviating left and right, ensuring that the limit hole can be aligned with the ejector rod. At the same time, the second chamfer can further prevent the PCB milling cutter from getting stuck during the rising process.

[0021] The synchronous transmission mechanism comprises an engagement block fixed on the first crossbar, a notch is provided in the middle of the first fixed plate, engagement teeth are arranged inside the notch, and the engagement block matches the gap between two adjacent engagement teeth.

[0022] With the above structure, when in use, when the quick-release handle moves with the placement disk, the engaging block gradually approaches the conveyor belt, and after contacting the engaging teeth, it can drive the conveyor belt to run by squeezing the engaging teeth, and the engaging block is just stuck between the two engaging teeth, so the position of the limit hole can be determined, and the limit hole is kept aligned with the PCB milling cutter. When there is no disk placed on the conveyor belt, the conveyor belt will not run, which can reduce energy consumption.

[0023] A plurality of support plates are fixed on both sides of the trapezoidal support block, and the support plates are fitted with the inside of the conveyor belt, and the support plates and the top rod are separated from each other, and a plurality of passage grooves are opened on the rotating roller, and the passage grooves are aligned with the top rod.

[0024] With the above structure, when in use, the support plate can support the conveyor belt to prevent the conveyor belt from bending downward due to the gravity of the placement plate, causing the PCB milling cutter to be unable to align with the limit hole, and the support plate and the rotating roller with a passage groove will not hinder the movement of the ejector rod, thereby improving the smoothness of the equipment operation.

[0025] Compared with the prior art, the continuous cleaning device for PCB milling cutter production has the following advantages:

[0026] 1. Through the ultrasonic cleaning pool, conveyor belt, conveyor belt, lifting mechanism and the first fixed plate, the PCB milling cutter can be cleaned in batches during the movement, and the PCB milling cutter can be separated from the placement plate during the cleaning process, and the cutter head and the handle of the PCB milling cutter can be fully cleaned respectively, thereby improving the cleaning effect of the PCB milling cutter.

[0027] 2. Through the synchronous transmission mechanism, the conveyor belt and the milling cutter are driven to run synchronously. On the one hand, it can ensure that the PCB milling cutter can be aligned with the limit hole to improve the stability of the equipment operation. On the other hand, the conveyor belt can be stopped when the placement plate is not moved under the conveyor belt, reducing energy consumption and saving costs. BRIEF DESCRIPTION OF THE DRAWINGS
