Description

Technical Field

[0001] The present application relates to the field of circuit board production equipment, and in particular to a circuit board separation equipment. Background Art

[0002] Circuit board, or PCB board, is also called printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. In the production process of circuit boards, in order to improve the production efficiency of circuit boards, circuit boards are generally passed through the furnace in a splicing manner to complete part of the manufacturing process. After passing through the furnace, the circuit boards need to be separated.

[0003] At present, a circuit board is generally separated by a board separation machine. Specifically, the circuit board is milled by a milling cutter. A large amount of dust or debris is generated in this process. In the existing related technologies, air blowing or suction is used to deal with the dust.

[0004] However, this method can only remove the dust floating in the air, but the dust adhering to the circuit board cannot be removed. In addition, during blowing or suction, dust will still float, affecting the observation of the turning and milling status, and it is impossible to adjust the operating parameters of the milling cutter in time, which will have an adverse effect on the board separation accuracy. Summary of the invention

[0005] In order to improve the problem that a large amount of dust is generated during the circuit board separation process, which affects the operating environment and the circuit board separation accuracy, the present application provides a circuit board separation device.

[0006] The present application provides a circuit board separation device, which adopts the following technical solution:

[0007] A circuit board depaneling device comprises a machine platform, a depaneling chamber is provided on the machine platform, a feeding unit and a milling unit are provided in the depaneling chamber; the feeding unit comprises a feeding platform and a slide rail, the milling unit comprises a milling cutter movable in the depaneling chamber, a ring-shaped enclosure is provided on the top of the feeding platform, the circuit board to be milled is inserted on the enclosure in a horizontal direction, a water distribution unit is provided on the top of the enclosure, the water distribution unit is used to distribute a water film flowing in a horizontal direction to the top of the circuit board, the milling cutter passes through the water film and mills the circuit board.

[0008] By adopting the above technical solution, the water distribution unit will form a water film on the surface of the circuit board, and the milling cutter needs to pass through the water film to turn and mill the circuit board. In this way, the dust generated during the turning and milling process can be covered by the water film, thereby generating wastewater carrying dust. The wastewater can flow on the circuit board and flow to the outside of the circuit board, effectively preventing dust from floating around in the board separation room. At the same time, it can also play a role in cleaning the circuit board, making the board separation more accurate.

[0009] Optionally, a sunken sewage outlet is provided at the inner bottom of the panel separation chamber, and the sewage outlet is in the shape of a funnel with a gradually decreasing inner diameter; the feeding platform is in the shape of a square shell with an open bottom, and the two sides of the bottom of the feeding platform are mounted on the slide rails, and the top of the feeding platform is in the shape of a mesh plate, and the enclosure is arranged around the top of the feeding platform, and the water distribution unit is arranged at one end of the enclosure close to the outer side of the panel separation chamber, and the circuit board is inserted into the inner side of the enclosure from below the water distribution unit, and the bottom of the circuit board is separated from the top of the feeding platform, and the side of the circuit board away from the water distribution unit is separated from the end of the enclosure away from the outer side of the panel separation chamber.

[0010] By adopting the above technical solution, the circuit board will be suspended after being inserted into the enclosure. In this way, the water film will flow in the direction away from the water distribution unit, thereby taking the dust generated during the turning and milling process away from the circuit board, and passing through the top of the feed table and flowing into the drain port, thereby realizing rapid recovery of the dust.

[0011] Optionally, the turning and milling unit also includes two X-axis slides, a Y-axis slide and a Z-axis slide, the two ends of the Y-axis slide are respectively mounted on the two X-axis slides, the X-axis slide is used to drive the Y-axis slide to move in the X-axis direction, the Y-axis slide is used to drive the Z-axis slide to move in the Y-axis direction, the milling cutter is arranged on the Z-axis slide, the Z-axis slide is used to drive the milling cutter to move along the Z-axis direction, and a visual camera is also provided on the Z-axis slide, and the visual camera is used to shoot and transmit the turning and milling images; when the milling cutter is turning and milling the circuit board, the feeding table is located above the drain outlet, and the area of ​​the feeding table is smaller than the area of ​​the drain outlet.

[0012] By adopting the above technical solution, after the circuit board is sent into the board separation room through the feeding table, the X-axis slide, the Y-axis slide and the Z-axis slide will produce corresponding actions, thereby realizing the arbitrary movement of the milling cutter in the X-axis direction, the Y-axis direction and the Z-axis direction, ensuring that the milling cutter can reliably turn and mill the circuit board, thereby realizing the board separation operation.

[0013] Optionally, a scraper is provided in the board separation chamber, the scraper is located at the end of the slide rail and is perpendicular to the slide rail, the bottom of the scraper is in contact with the bottom of the board separation chamber, the scraper and the inner wall of the board separation chamber are connected by a plurality of compression springs, when the milling cutter mills the circuit board, the feeding table contacts the scraper and the compression spring is in a compressed state.

[0014] By adopting the above technical solution, when the feeding table transports the circuit board, it will push the scraper to move toward the inside of the board separation chamber and compress the compression spring. When the circuit board is milled and the feeding table and the circuit board are evacuated, the compression spring will push the scraper to reset. During this process, the scraper will scrape the dust between the scraper and the drain port into the drain port, thereby achieving a scraping effect on the board separation chamber.

[0015] Optionally, the water distribution unit includes a shell, a fixed shaft and a movable shaft, the side surface of the shell is in an inverted convex shape, a drain outlet is provided at the bottom of the shell, the fixed shaft is provided in the drain outlet, the movable shaft is provided on the inner side of the shell, a hydraulic cylinder is also provided in the shell, the hydraulic cylinder is used to drive the movable shaft to move toward the drain outlet and be flush with the fixed shaft in the horizontal direction; the outer wall of the fixed shaft and the outer wall of the movable shaft are wrapped with sponge covers, and the two sponge covers interfere with each other in the vertical direction. When the movable shaft is flush with the fixed shaft, the bottoms of the two sponge covers are located below the drain outlet and in contact with the top of the circuit board.

[0016] By adopting the above technical solution, during milling, the sponge sleeve on the fixed shaft is located in the drain port and fits with the top of the circuit board, while the sponge sleeve on the movable shaft is located on the inner side of the shell and above the sponge sleeve of the fixed shaft. In this way, a water flow channel can be formed between the two sponge sleeves. The height of the movable shaft is adjusted by the hydraulic cylinder, and then the size of the water flow channel is adjusted to ensure that pure water can form a water film on the surface of the circuit board after flowing out of the shell. Furthermore, when the movable shaft moves to the lower part of the shell, the two sponge sleeves will squeeze each other to remove the pure water in the sponge sleeves. At this time, the circuit board is pulled out, and the two sponge sleeves will wipe the circuit board to improve the cleanliness of the circuit board surface.

[0017] Optionally, a water pipe is provided on both sides of the shell, and the water pipe extends at the top of the enclosure and toward the scraper, one end of the water pipe is connected to the inner side of the shell, and the other side of the water pipe extends to the outer side of one end of the enclosure close to the scraper; two water supply pipes are provided on the scraper, and the inner diameter of the water supply pipe is larger than the outer diameter of the water pipe. When the compression spring is in a compressed state, the two water pipes are respectively and one-to-one inserted into the two water supply pipes, and the water supply pipes are used to transport pure water to the water pipes and the shell.

[0018] By adopting the above technical solution, when the feeding table moves to the processing position, the water pipe on the top of the enclosure will be inserted into the water supply pipe of the scraper, so that pure water can be transported into the shell through the water supply pipe, thereby realizing water distribution.

[0019] Optionally, a vertical accommodating groove is provided at the bottom of one end of the feeding platform close to the outer side of the dividing panel chamber, and a scraper strip is provided in the vertical accommodating groove, and the scraper strip is connected to the bottom of the vertical accommodating groove by a plurality of vertical springs; two sloped tracks are also provided at the bottom of the dividing panel chamber, and the two sloped tracks are located between a pair of slide rails, and the sloped tracks are arranged close to the inner side of the slide rails; the height of the sloped track gradually decreases from the direction toward the inner side of the dividing panel chamber, and the end of the scraper strip slides on the top of the sloped track, and when the scraper strip contacts the highest point of the sloped track, the scraper strip is completely located in the vertical accommodating groove.

[0020] By adopting the above technical solution, when the feeding table conveys the circuit board outward, interference will occur between the feeding table and the sloped track, so that the scraper bar can move upward to the inner side of the vertical accommodating groove, thereby ensuring that the sloped track will not hinder the movement of the feeding table.

[0021] Optionally, the sloped track is located outside the sewage outlet and close to the outside of the plate separation chamber, and the length of the sloped track is less than the length of the feeding platform.

[0022] By adopting the above technical solution, when the feeding table is located at the processing position, the sloped track and the feeding table are separated from each other, thus ensuring that the feeding table can be in a stable state.

[0023] Optionally, a transverse accommodating groove is provided at both ends of the scraper strip, a movable bar and a transverse spring are inserted in the transverse accommodating groove, one end of the movable bar is located outside the transverse accommodating groove, and the other end of the movable bar is connected to one end of the transverse spring; a slope surface is provided on the side of the movable bar facing the sloped track, and there is interference between the slope surface and the end of the sloped track.

[0024] By adopting the above technical solution, when the feeding table conveys the circuit board inward, the movable bar will interfere with the sloped track, so that the movable bar can be retracted into the horizontal receiving groove while the scraper bar does not retract into the vertical receiving groove. In this way, the part of the movable bar located outside the horizontal receiving groove and the scraper bar can form a scraping effect on the board separation chamber, thereby preventing waste water from accumulating at the bottom of the board separation chamber.

[0025] Optionally, the transverse accommodating groove is connected to the bottom of the scraper strip, the bottom of the movable strip is flush with the bottom of the scraper strip, the upper part of the transverse accommodating groove is dovetail-shaped, the upper part of the scraper strip is adaptively arranged on the upper part of the transverse accommodating groove, and the transverse spring is connected to the lower inner wall of the transverse accommodating groove.

[0026] By adopting the above technical solution, it is ensured that the movable bar can only be extended and retracted in the horizontal direction in the transverse accommodating groove, and the movable bar will not fall out of the transverse accommodating groove when the scraper bar is retracted into the vertical accommodating groove.

[0027] In summary, this application has the following beneficial effects:

[0028] 1. A flowing water film is formed on the surface of the circuit board through the water distribution unit, so that when the milling cutter passes through the water film and mills the circuit board, the water film can block and absorb the dust generated by the milling, and bring the dust into the sewage outlet, ensuring that the surface of the circuit board is clean, which is beneficial to improving the operating environment and the accuracy of the board separation.

[0029] 2. When the feeding table enters the processing position, the slope of the movable bar will interfere with the sloped track, causing the movable bar to retract into the horizontal accommodating groove. During this process, the movable bar and the scraper bar both remain in contact with the bottom of the plate separation chamber, thereby being able to scrape the waste water at the bottom of the plate separation chamber into the drain outlet.

[0030] 3. When the feeding table is withdrawn from the processing position, the flat surface of the movable bar will interfere with the sloped track, so that the movable bar can drive the scraper bar to retract into the vertical accommodating groove as a whole, ensuring that the scraper bar and the movable bar do not contact the bottom of the plate separation chamber during the withdrawal process, preventing the scraper bar and the movable bar from scraping waste water to the outside of the plate separation chamber.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-8 This application is described in further detail.

[0041] Figure 1 is a schematic stereogram of the present application, Figure 2 It is a schematic diagram of the internal structure of the panel separation chamber in this application. Figure 1 and Figure 2 A circuit board depaneling device comprises a machine platform 1, a depaneling chamber 2 is arranged on the machine platform 1, a feeding unit 3, a milling unit 4 and a water distribution unit 6 are arranged in the depaneling chamber 2, the feeding unit 3 is used for pushing a circuit board 5 to be milled into the depaneling chamber 2, the milling unit 4 is used for milling the circuit board 5, so as to realize the depaneling operation, the water distribution unit 6 is used for forming a flowing water film on the surface of the circuit board 5, the dust generated when the milling unit 4 mills the circuit board 5 will be covered by the water film, and in the process of the water film flowing, the dust can be taken away from the surface of the circuit board 5, so as to prevent the dust from floating and polluting the operating environment, and also can play the effect of improving the depaneling accuracy.

[0042] Figure 3 This is a reference diagram of the assembly status of the feeder table and the water distribution unit. Figure 3 Combined with Figure 2The feeding unit 3 includes a feeding platform 31 and two slide rails 32. The feeding platform 31 is in the shape of a square shell with an open bottom. The two sides of the bottom of the feeding platform 31 are mounted on the two slide rails 32. The top of the feeding platform 31 is in the shape of a mesh plate. The outer edge of the top of the feeding platform 31 is provided with a ring-shaped enclosure 33. The circuit board 5 is inserted into the enclosure 33 through a side wall in the width direction of the enclosure 33, and the circuit board 5 is separated from the other side wall in the width direction of the enclosure 33. Specifically, a socket is provided on a side wall in the width direction of the enclosure 33, and a slide groove is provided on both side walls in the length direction of the enclosure 33. The two slide grooves and a socket are arranged in a U shape, so that the circuit board 5 can be inserted into the slide groove through the socket and fixed on the inner side of the enclosure 33. At the same time, after the circuit board 5 is inserted into the enclosure 33, its bottom is separated from the top of the feeding platform 31, that is, the circuit board 5 will be in a suspended state, thereby preventing the accumulation of dust without affecting the milling and board separation operations. A drain outlet 21 is provided at the bottom of the panel separation chamber 2, and the drain outlet 21 is located between two slide rails 32. When the feeding table 31 moves to the processing position, the feeding table 31 will be located above the drain outlet 21, and the size of the drain outlet 21 will be larger than the area of ​​the feeding table 31, thereby ensuring that all dust generated during the panel separation process can be discharged to the outside through the drain outlet 21, avoiding pollution to the operating environment of the panel separation chamber 2.

[0043] See also Figure 1 and Figure 2 The turning and milling unit 4 includes a moving mechanism and a milling cutter 41. The moving mechanism is used to drive the milling cutter 41 to move freely in the board separation chamber 2. Specifically, the moving mechanism includes two X-axis slides 42, a Y-axis slide 43 and a Z-axis slide 44. The two ends of the Y-axis slide 43 are respectively mounted on the two X-axis slides 42. The X-axis slide 42 is used to drive the Y-axis slide 43 to move in the X-axis direction, and the Y-axis slide 43 is used to drive the Z-axis slide 44 to move in the Y-axis direction. The milling cutter 41 is arranged on the Z-axis slide 44, and the Z-axis slide 44 is used to drive the milling cutter 41 to move along the Z-axis direction. The milling cutter 41 is arranged on the Z-axis slide 44. In this way, through the cooperation of the X-axis slide 42, the Y-axis slide 43 and the Z-axis slide 44, the milling cutter 41 can be moved in the X-axis direction, the Y-axis direction or the Z-axis direction in the board separation chamber 2, thereby realizing the turning, milling and board separation of the circuit board 5. Furthermore, a visual camera 45 is also provided on the Z-axis slide 44. The visual camera 45 is used to capture and transmit images of the turning and milling screen to a device with storage and analysis capabilities, thereby reliably controlling the accuracy of the split board.

[0044] Figure 4 This is a cross-sectional view of the internal structure of the water distribution unit. Figure 4 Combined with Figure 2The water distribution unit 6 is arranged at one end of the enclosure 33 close to the outer side of the panel chamber 2, and the circuit board 5 is inserted into the inner side of the enclosure 33 from the bottom of the water distribution unit 6. The water distribution unit 6 includes a shell 61, a fixed shaft 62 and a movable shaft 63. The side of the shell 61 is in an inverted convex shape, that is, the shell 61 is connected to the enclosure 33 and the lower inner diameter of the shell 61 is smaller than the upper inner diameter of the shell 61. A drain port 611 is provided at the bottom of the shell 61, the fixed shaft 62 is fixedly provided at the drain port 611, and the movable shaft 63 is movably provided at the inner upper part of the shell 61. A hydraulic cylinder 612 is provided at the inner top of the shell 61, and the push rod of the hydraulic cylinder 612 is used to push the movable shaft 63 to move up and down in the shell 61. The outer wall of the movable shaft 63 and the outer wall of the fixed shaft 62 are both wrapped with a sponge cover 630, the upper part of the sponge cover 630 on the fixed shaft 62 is located in the housing 61, and the bottom of the sponge cover 630 on the fixed shaft 62 is in contact with the circuit board 5, and the sponge cover 630 on the movable shaft 63 is all located on the inner side of the housing 61. When the movable shaft 63 is located at the upper limit position, the movable shaft 63 is located obliquely above the fixed shaft 62, so that a water outlet gap is formed between the sponge cover 630 of the movable shaft 63 and the sponge cover 630 of the fixed shaft 62, and the pure water in the housing 61 needs to pass through the water outlet gap and the drain port 611 to be discharged outward. In this way, by adjusting the position of the movable shaft 63, the water outlet gap can be adjusted, and then it is ensured that when the pure water is discharged from the water outlet gap and the drain port 611 to the circuit board 5, a flowing water film can be reliably formed on the circuit board 5, so that the milling cutter 41 needs to pass through the water film before it can contact the circuit board 5 and complete the milling and board separation of the circuit board 5. Furthermore, the circuit board 5 can be obliquely inserted into the enclosure 33, and the end of the circuit board 5 close to the shell 61 is higher than the end of the circuit board 5 away from the shell 61, so that the water film can reliably flow on the top of the circuit board 5, and the end of the circuit board 5 away from the shell 61 is in a state of separation from the enclosure 33. The water film entrains dust generated during the milling process to form wastewater. After the wastewater flows to the end of the circuit board 5 away from the shell 61, it can directly pass through the mesh-shaped feeding platform 31 and enter the sewage outlet 21. The sewage outlet 21 is set to sink and is in the shape of a funnel with a gradually decreasing inner diameter. In this way, it is ensured that all the wastewater passing through the feeding platform 31 can enter the sewage outlet 21 and be discharged outward, ensuring the cleanliness of the operating environment.

[0045] When the water distribution unit 6 is in the water distribution state, the sponge sleeve 630 on the movable shaft 63 and the sponge sleeve 630 on the fixed shaft 62 are separated from each other and interfere with each other in the vertical direction. When the circuit board 5 is separated and the water distribution unit 6 stops distributing water, the hydraulic cylinder 612 drives the movable shaft 63 to move to the lower limit. At this time, the movable shaft 63 and the fixed shaft 62 are flush in the horizontal direction, and the sponge sleeve 630 on the movable shaft 63 and the sponge sleeve 630 on the fixed shaft 62 will form mutual extrusion and deformation, thereby squeezing out the pure water in the two sponge sleeves 630. The displacement during the extrusion process will be greater than the displacement during water distribution. In this way, the flushing effect on the circuit board 5 can be achieved while reducing the water consumption. At the same time, when the movable shaft 63 is located at the lower limit position, the sponge cover 630 on the movable shaft 63 and the sponge cover 630 on the fixed seat will both contact the top of the circuit board 5. In this way, when the circuit board 5 is pulled out after turning and milling, the two relatively dry sponge covers 630 will form a scrubbing effect on the circuit board 5, effectively removing the residual pure water and dust on the surface of the circuit board 5.

[0046] See also Figure 1 and Figure 2 A scraper 22 is provided in the plate-dividing chamber 2. The scraper 22 is located at the end of the slide rail 32 and is perpendicular to the slide rail 32. The bottom of the scraper 22 is in contact with the bottom of the plate-dividing chamber 2. The scraper 22 is connected to the inner wall of the plate-dividing chamber 2 by a plurality of compression springs 221. Two water supply pipes 222 connected to a water source are also provided on the scraper 22. A water pipe 64 is provided on both sides of the top of the enclosure 33. One end of the water pipe 64 is connected to the housing 61, and the other side of the water pipe 64 extends to the outer side of one end of the enclosure 33 close to the scraper 22. The inner diameter of the water supply pipe 222 is larger than the outer diameter of the water delivery pipe 64. When the feeding table 31 moves to the processing position and the milling cutter 41 can mill the circuit board 5, the scraper 22 will be pushed away from the drain outlet 21. At this time, the compression spring 221 will be in a compressed energy storage state, and in the process of the feeding table 31 pushing the scraper 22, the two water delivery pipes 64 will be inserted into the two water supply pipes 222 one by one. In this way, the water source can transport pure water to the shell 61 through the water supply pipe 222 and the water delivery pipe 64, thereby ensuring that the pure water can form a water film on the top of the circuit board 5 after flowing out of the shell 61. After the milling cutter 41 completes the turning, milling and panel separation operations on the circuit board 5, the feeding table 31 will withdraw from the processing position. At this time, the compression spring 221 will release energy and rebound, thereby pushing the scraper 22 to move toward the direction close to the drain outlet 21. In this way, the scraper 22 will scrape the bottom of the panel separation chamber 2, thereby scraping the waste water generated during the turning and milling process into the drain outlet 21, and when the scraper 22 stops moving, the scraper 22 will be located above the drain outlet 21, effectively reducing the scraping dead angle.

[0047] Figure 5 It is the reference for the assembly status of the feeding table and the slope track. Figure 1 , Figure 6This is a cross-sectional view of the internal structure of the feeding table. Figure 5 and Figure 6 Combined with Figure 2 A vertical accommodating groove 310 is provided at the bottom of one end of the feeding platform 31 close to the outer side of the panel separation chamber 2. A scraper bar 7 is provided in the vertical accommodating groove 310. The scraper bar 7 is connected to the bottom of the vertical accommodating groove 310 through a plurality of vertical springs 71. Two sloped tracks 23 are also provided at the bottom of the panel separation chamber 2. The two sloped tracks 23 are located between a pair of slide rails 32. The sloped tracks 23 are arranged close to the inner side of the slide rails 32. The height of the sloped tracks 23 gradually decreases from the direction toward the inner side of the panel separation chamber 2. The sloped tracks 23 are located outside the sewage outlet 21 and close to the outer side of the panel separation chamber 2. The length of the sloped tracks 23 is less than the length of the feeding platform 31. A transverse accommodating groove 72 is provided at each end of the scraper strip 7, and a movable bar 73 and a transverse spring 74 are inserted in the transverse accommodating groove 72. One end of the movable bar 73 is located outside the transverse accommodating groove 72, and the other end of the movable bar 73 is connected to one end of the transverse spring 74; a slope surface 730 is provided on the side of the movable bar 73 facing the sloped track 23, and there is interference between the slope surface 730 and the end of the sloped track 23.

[0048] When the feeding platform 31 is close to the outside of the board separation chamber 2, the circuit board 5 to be milled can be loaded on the feeding platform 31. At this time, the bottom of the side of the feeding platform 31 with the vertical accommodating groove 310 is located outside the slope track 23, while the bottom of the side of the feeding platform 31 without the vertical accommodating groove 310 is away from the slope track 23. In the current state, the vertical spring 71 and the transverse spring 74 are both in a naturally extended state, and the scraper bar 7 and the movable bar 73 are both kept in contact with the bottom of the board separation chamber 2. When the feeding table 31 moves toward the processing position, the slope surface 730 of the movable bar 73 will contact the end face of the sloped track 23 with a higher height. When interference occurs between the two, under the guidance of the slope surface 730, the sloped track 23 will press the movable bar 73 into the horizontal accommodating groove 72, so that the movable bar 73 contacts the side of the sloped track 23. In this way, while the movable bar 73 and the scraper bar 7 remain in contact with the bottom of the plate separation chamber 2, the feeding table 31 can reliably move toward the processing position. That is to say, when the feeding table 31 moves toward the processing position, the movable bar 73 and the scraper bar 7 can form a scraping effect on the bottom of the plate separation chamber 2, and the scraped waste water can all enter the sewage outlet 21.

[0049] Figure 7 It is the reference for the assembly status of the feeding table and the slope track. Figure 2 , Figure 8 This is a reference diagram of the explosion state of the feeding table. Figure 7 and Figure 8 Combined with Figure 2When the feeding table 31 is located at the processing position, the turning and milling operation of the circuit board 5 can be performed. At this time, the bottom of one end of the feeding table 31 having the vertical accommodating groove 310 is separated from the slope track 23. When the milling and panel separation operations on the circuit board 5 are completed, the feeding table 31 will move toward the outside of the panel separation chamber 2. In this process, the flat surface of the movable bar 73 will move toward the lower end of the sloped track 23. Since the height of the end surface of the lower end of the sloped track 23 is close to zero, the movable bar 73 can move the top of the sloped track 23. At this time, the movable bar 73 cannot move horizontally or vertically in the horizontal accommodating groove 72, which will enable the movable bar 73 and the scraper bar 7 as a whole to move toward the inner side of the vertical accommodating groove 310 at the same time. In this way, it is ensured that when the feeding table 31 is away from the processing position, the scraper bar 7 and the movable bar 73 are in a state of separation from the bottom of the panel separation chamber 2, which can effectively prevent the scraper bar 7 and the movable bar 73 from scraping the waste water accumulated at the bottom of the panel separation chamber 2 to the outside of the panel separation chamber 2 during the withdrawal of the feeding table 31 from the processing position, thereby further improving the operating environment and reducing the difficulty of cleaning the panel separation chamber 2 at a later time.

[0050] The transverse groove 72 is connected to the bottom of the scraper 7, the bottom of the movable bar 73 is flush with the bottom of the scraper 7, the upper part of the transverse groove 72 is dovetail-shaped, the upper part of the scraper 7 is adaptively arranged on the upper part of the transverse groove 72, and the transverse spring 74 is connected to the lower inner wall of the transverse groove 72, so that when the vertical spring 71 is in a naturally extended state, the movable bar 73 and the scraper 7 can both contact the bottom of the plate separation chamber 2, thereby improving the scraping effect on the bottom of the plate separation chamber 2. The upper part of the transverse groove 72 is dovetail-shaped, which ensures that the movable bar 73 can only move horizontally along the length direction of the transverse groove 72 in the transverse groove 72, thereby ensuring that when the feeding table 31 withdraws from the processing position, the movable bar 73 can drive the scraper 7 to move into the vertical groove 310, thereby ensuring that the scraper 7 and the movable bar 73 are in a state of separation from the bottom of the plate separation chamber 2 during the withdrawal process.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
