Description

Technical Field

[0001] The present invention relates to a waste liquid stripping mechanism for a ton barrel stripping liquid, belonging to the technical field of ton barrel cleaning. Background Technique

[0002] Ton barrels are essential tools for modern warehousing and transporting liquid products. They are blow-molded from high molecular weight high-density polyethylene, with high strength, corrosion resistance, and good hygiene.

[0003] With the popularity of smart handheld devices and mobile terminals, the electronic manufacturing industry and optoelectronic industry have developed rapidly. Since in the manufacturing processes of printed circuit boards, liquid crystal display panels, semiconductor integrated circuits, etc., it is necessary to form multiple layers of precise microcircuits on silicon wafers or glass substrates through multiple processes such as graphic mask irradiation exposure and etching. Then, a stripping liquid is used to remove the photoresist used as a mask coated on the protected area of the microcircuits. Usually, this step is called photoresist removal. In the wet processing production process of printed circuit boards, in the demolding (film stripping) process to remove residual solder on the surface of waste circuit boards, a large amount of stripping liquid will also be generated.

[0004] Since the stripping liquid is a recyclable product, the generated stripping liquid needs to be stored and transported using ton barrels. In order to avoid impurities remaining from the previous process on the inner wall of the ton barrel during subsequent use, it is necessary to clean and dry the ton barrel.

[0005] For example: CN111515193B, a ton barrel cleaning device, solves the problems in the related technology that the cleaning of ton barrels is not thorough and new impurity ions are easily introduced into the canned chemicals. However, it uses a spraying technology, and the stripping liquid on the inner side wall of the ton barrel being cleaned solidifies and adheres to the inner side wall of the ton barrel. The reaction time between the cleaning liquid and the stripping liquid adhering to the inner side wall of the ton barrel is short, and the effect is poor. Summary of the Invention

[0006] The purpose of the present invention is to provide a waste liquid stripping mechanism for a ton barrel stripping liquid to solve the problems raised in the above background technique.

[0007] The technical solution of the present invention is as follows: A waste liquid stripping mechanism for a ton barrel stripping liquid, comprising: A bottom plate, on both left and right side edges of the bottom plate, a plurality of straight clamping rods are hinged, and on both front and rear side edges of the bottom plate, a plurality of L-shaped clamping rods are hinged; A driving assembly, the driving assembly is used to push a plurality of straight clamping rods and a plurality of L-shaped clamping rods to close or expand synchronously, so as to clamp and fix the ton barrel or release it; A hollow shaft, the hollow shaft is driven by a lifting assembly to enter and exit the feed port at the top of the ton barrel, and the inside of the hollow shaft is connected to an air source outside; The profiling airbag is sleeved on the outer wall of the hollow shaft and is in communication with the inside of the hollow shaft. First magnetic members are uniformly arranged on each side surface of the profiling airbag; Second magnetic members are arranged on the bottom plate, the straight clamping rods and the L-shaped clamping rods, and the second magnetic members are magnetically repulsively matched with the first magnetic members.

[0008] Preferably, the driving assembly includes a lifting device and a pushing ring located at the upward output end of the lifting device. When the lifting device rises, it abuts against a plurality of straight clamping rods and a plurality of L-shaped clamping rods through the inner side wall of the pushing ring to achieve folding.

[0009] Preferably, first elastic members are arranged on the side walls of the straight clamping rods and the L-shaped clamping rods. When the straight clamping rods and the L-shaped clamping rods clamp and fix the ton barrel, the corresponding first elastic members generate reverse elastic forces.

[0010] Preferably, a liquid outlet valve is installed on the hollow shaft, and the liquid outlet valve is connected to an external cleaning liquid assembly through a pipeline.

[0011] Preferably, the first magnetic member includes a rigid magnetic strip and a flexible magnetic strip. The flexible magnetic strip is arranged on the upper and lower side surfaces of the profiling airbag, and the rigid magnetic strip is arranged on the four side surfaces of the profiling airbag.

[0012] Preferably, a rotating shaft is coaxially rotatably connected to the inside of the hollow shaft through a driving motor, and the rotating shaft and each rigid magnetic strip are connected by corresponding traction ropes.

[0013] Preferably, a normally closed valve is installed on the rigid magnetic strip, a jet nozzle is arranged on the hollow shaft, the traction rope passes through the corresponding jet nozzle, and when the rigid magnetic strip fits against the outer wall of the hollow shaft, the jet nozzle and the normally closed valve are integrated and the normally closed valve is opened.

[0014] Preferably, the normally closed valve includes a first valve body, a first channel adapted to the jet nozzle, a first fixing member fixed in the first channel, a first gate for opening or closing the first channel, and a linkage structure. The first fixing member is fixedly connected to one end of the traction rope; when the jet nozzle is inserted into the first channel, the first gate is controlled to open the first channel through the linkage structure.

[0015] Preferably, the linkage structure includes a second elastic member, a connecting rod, a push rod and a third elastic member. The second elastic member pushes the first gate to close the first channel under normal conditions; the push rod is linearly slidably arranged along the length extension direction of the first channel, the third elastic member pushes the push rod to tend to reset, and a guiding groove is formed on the push rod; the fixed end of the connecting rod is fixedly connected to the first gate, and the movable end is slidably matched with the guiding groove.

[0016] Preferably, the guiding groove includes a straight section and a slope section; when the movable end of the connecting rod is placed within the straight section, the first gate closes the first channel; when the movable end of the connecting rod is placed within the slope section, the first gate opens the first channel.

[0017] Preferably, the normally closed valve includes a second valve body, a second valve, a fourth elastic member, and a second fixing member. The second valve closes the outer end of the second channel of the second valve body under the elastic force of the fourth elastic member in the normal state.

[0018] Preferably, the flexible magnetic strip includes a number of mutually independent magnetic blocks arranged in a line.

[0019] Preferably, both the rigid magnetic strip and the magnetic blocks adopt an electromagnet structure.

[0020] The present invention has the following beneficial effects: Through the cooperation of the straight clamping rods and L-shaped clamping rods around the bottom plate, the clamping and fixing of the ton barrel located on the bottom plate are realized, and at the same time, the position correction of the ton barrel is achieved. The lifting assembly drives the hollow shaft and the profiling airbag to insert into the ton barrel. The profiling airbag is inflated and expanded. After expansion, the volume of the profiling airbag is slightly smaller than the inner cavity space of the ton barrel. At the same time, through the magnetic repulsion cooperation between the second magnetic member and the first magnetic member, a certain gap is left between each outer wall of the profiling airbag and each inner wall of the ton barrel. The cleaning liquid is poured into the inner cavity of the ton barrel through the liquid outlet valve. The cleaning liquid fills the gap between the outer wall of the profiling airbag and the inner wall of the ton barrel, which is beneficial to reducing the usage amount of the cleaning liquid and at the same time ensuring that each inner wall of the ton barrel is soaked by the cleaning liquid.

Specific embodiments

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Embodiment 1: As Figures 1-8 shown: The ton barrel 100 is made of non-metallic material and will not have magnetic cooperation with the magnetic member; The bottom plate 1 is relatively fixedly arranged, and a lifting assembly (not shown in the drawings) can be arranged above the bottom plate 1 by using a telescopic cylinder; a plurality of straight clamping rods 2 are hinged to the left and right side edges of the bottom plate 1, and a plurality of L-shaped clamping rods 3 are hinged to the front and rear side edges of the bottom plate 1; the lifting device 61 can be arranged below the bottom plate 1 by using a telescopic cylinder, and the vertically upward output end of the lifting device 61 is fixedly connected to the push ring 6. As Figure 3 shown, a first elastic member 21 is arranged inside each straight clamping rod 2 and each L-shaped clamping rod 3.

[0025] As Figure 2As shown in the figure, when the ton barrel 100 is roughly adjusted in orientation and placed on the bottom plate 1, the lifting device 61 drives the push ring 6 at its output end to move upward. During this process, the inner sidewall of the push ring 6 abuts against the outer sidewalls of each straight clamping rod 2 and each L-shaped clamping rod 3, thereby pushing each straight clamping rod 2 and each L-shaped clamping rod 3 to rotate synchronously, achieving the closing effect; enabling the straight clamping rods 2 in the left row to be vertical and abut against the left sidewall of the ton barrel 100, and the straight clamping rods 2 in the right row to be vertical and abut against the right sidewall of the ton barrel 100; the vertical ends of the L-shaped clamping rods 3 in the front row to be vertical and abut against the front sidewall of the ton barrel 100, and the horizontal ends of the L-shaped clamping rods 3 in the front row to be placed above the front part of the ton barrel 100; the vertical ends of the L-shaped clamping rods 3 in the rear row to be vertical and abut against the rear sidewall of the ton barrel 100, and the horizontal ends of the L-shaped clamping rods 3 in the rear row to be placed above the rear part of the ton barrel 100; meanwhile, the respective first elastic members 21 abut against the sidewalls of the ton barrel 100 and are compressed to generate reverse elastic forces.

[0026] The straight clamping rods 2 and the L-shaped clamping rods 3 cooperate to clamp and fix the ton barrel 100 on the bottom plate 1, and at the same time correct the ton barrel 100, which is beneficial for the feed inlet 101 of the ton barrel 100 after being clamped to just align with the hollow shaft 4 directly above it.

[0027] After cleaning and peeling are completed, the lifting device 61 drives the push ring 6 at its output end to move downward and reset. The elastic force of the first elastic member 21 pushes the respective straight clamping rods 2 / L-shaped clamping rods 3 to rotate in the reverse direction; making the straight clamping rods 2 on the left and right sides of the bottom plate 1 rotate to the horizontal state is beneficial for the entry and exit of the ton barrel.

[0028] As Figure 1 shown, the inner cavity of the hollow shaft 4 is connected to an external air source (positive pressure air source and negative pressure air source). The outer wall of the hollow shaft 4 is provided with a profiling airbag 5. The inner cavity of the hollow shaft 4 is communicated with the inner cavity of the profiling airbag 5 through a jet nozzle 73; after the inner cavity of the profiling airbag 5 is inflated and expanded, its volume is slightly smaller than the inner cavity space of the ton barrel 100. An outlet valve is installed on the outer wall of the hollow shaft 4 outside the profiling airbag 5. The outlet valve is connected to an external cleaning liquid assembly through a pipeline, and a pump is installed on the pipeline. The cleaning liquid assembly includes a cleaning liquid tank, and the cleaning liquid tank is filled with cleaning liquid.

[0029] As Figure 4 shown, flexible magnetic strips 52 are uniformly installed on the upper and lower sidewalls of the profiling airbag 5, and rigid magnetic strips 51 are uniformly installed on the four sidewalls of the profiling airbag 5; when the profiling airbag 5 reduces its volume, each rigid magnetic strip 51 adheres to the outer sidewall of the hollow shaft 4, and the flexible magnetic strip 52 can be flexibly deformed to adapt, thereby facilitating reducing the volume and passing through the feed inlet 101 to enter the interior of the ton barrel 100; As Figure 5As shown in the figure, a coaxial rotating shaft 7 is rotatably connected to the inner cavity of the hollow shaft 4, and a driving motor 71 is used to drive the rotating shaft 7 to rotate; one end of a traction rope 72 is fixed to a rigid magnetic strip 51, and the other end passes through a corresponding jet nozzle 73 and enters the interior of the hollow shaft 4 and is wound around the outer wall of the rotating shaft 7. One rigid magnetic strip 51 corresponds to two traction ropes 72, and each traction rope 72 is distributed at different positions in the axial direction of the rotating shaft 7 to avoid mutual interference. The outer diameter of the traction rope 72 is smaller than the inner diameter of the jet nozzle 73.

[0030] After the profiling airbag 5 with a reduced size follows the hollow shaft 4 and is inserted into the interior of the ton barrel 100, a positive pressure air source outside delivers air into the interior of the hollow shaft 4. The positive pressure air source inside the hollow shaft 4 is delivered to the inner cavity of the profiling airbag 5 through a number of jet nozzles 73. The inner cavity of the profiling airbag 5 is inflated until it reaches a set air pressure value; the positions of the rigid magnetic strips 51 and flexible magnetic strips 52 on the inflated profiling airbag 5 are approximately corresponding to the second magnetic members on the straight clamping rods 2 and L-shaped clamping rods 3, which is beneficial to maximizing the magnetic force; through the magnetic repulsive cooperation between the second magnetic member and the first magnetic members (rigid magnetic strips 51 and flexible magnetic strips 52), the rigid magnetic strips 51 and flexible magnetic strips 52 are relatively far away from the inner wall of the ton barrel 100 by a certain distance, thereby driving each outer wall of the inflated profiling airbag 5 to be away from the corresponding inner wall of the ton barrel 100 by a certain distance; a small distance is left between each inner wall of the ton barrel 100 and each outer wall of the inflated profiling airbag 5, that is, the profiling airbag 5 does not directly contact the inner wall of the ton barrel 100. The profiling airbag 5 has a certain elastic deformation ability.

[0031] Since the profiling airbag 5 is not a rigid structure, there are certain differences from the set shape and position after inflation; if the inflated profiling airbag 5 abuts against the inner wall of the ton barrel 100, there will be soaking dead corners, reducing the peeling effect. Before the soaking process, it is necessary to close the discharge port 102 at the lower part of the ton barrel 100.

[0032] After that, the external cleaning liquid is poured into the inner cavity of the ton barrel 100 through the liquid outlet valve. The cleaning liquid fills the space between the ton barrel 100 and the inflated profiling airbag 5, so that the stripping liquid on each inner wall of the ton barrel 100 is soaked by the cleaning liquid. Soaking the inner wall of the ton barrel 100 with the cleaning liquid for a period of time is beneficial for the cleaning liquid to fully react with the fixed stripping liquid for a period of time; the ton barrel 100 has a large size, and if the entire inner cavity of the ton barrel 100 is filled, there will be a waste situation. Therefore, using the inflated profiling airbag 5 can greatly reduce the space to be filled, which is beneficial to reducing the usage amount of the cleaning liquid.

[0033] Such as Figure 5As shown in the figure, a normally closed valve 8 is provided on the rigid magnetic strip 51. One end of the towing rope 72 is connected to the corresponding normally closed valve 8, and the other end passes through the corresponding jet nozzle 73 and then winds around the outer wall of the rotating shaft 7. After reaching the soaking time, the discharge port 102 opens to discharge most of the cleaning liquid. The external controller controls the driving motor 71 to drive the rotating shaft 7 to rotate. The rotating shaft 7 rotates synchronously to wind all the towing ropes 72 around its outer wall. During this process, the rigid magnetic strip 51 is driven to approach the hollow shaft 4 until the jet nozzle 73 is relatively inserted into the corresponding normally closed valve 8 and integrated. At this time, the jet nozzle 73 communicates with the normally closed valve 8 and opens the normally closed valve 8. During this process, the profiling airbag 5 deforms as follows Figure 8 shown in the figure. At this time, the jet nozzle 73 is disconnected from the inner cavity of the profiling airbag 5, and the external air source sequentially passes through the hollow shaft 4 and the jet nozzle 73 and sprays out from the normally closed valve 8. The compressed air sprayed out by the normally closed valve 8 is not only conducive to blowing off the residual stripping liquid attached to the inner side wall of the ton barrel 100, but also conducive to blowing off the water attached to the outer side wall of the profiling airbag 5. At this time, the profiling airbag 5 is in an inflated state, which can avoid dirt accumulation caused by folding.

[0034] It also includes a rotating assembly (servo motor) that drives the lifting assembly to rotate, thereby driving the hollow shaft 4 to rotate, so as to realize the rotation of the normally closed valve 8 to spray air on the inner side wall of the ton barrel 100, which is conducive to improving the jet purging effect. The centrifugal force generated by the rotation is conducive to the water attached to the outer wall of the inflated profiling airbag 5 being thrown out. A number of normally closed valves 8 are relatively located at different positions on the axis of the hollow shaft 4.

[0035] After the normally closed valve 8 blows air outwards to complete the flushing, the driving motor 71 drives the rotating shaft 7 to rotate in the reverse direction to reset, so that the normally closed valve 8 is disconnected from the jet nozzle 73, and the jet nozzle 73 is reconnected to the inner cavity of the profiling airbag 5. Then, the external negative pressure air source extracts all the air in the profiling airbag 5 to reduce the size of the profiling airbag 5. After that, the reduced-size profiling airbag 5 can be extracted upwards from the feeding port 101, and then the ton barrel 100 can be simply washed with a water gun.

[0036] The water and other substances attached to the outer side wall of the extracted profiling airbag 5 are blown away by the jet in the previous process, avoiding the dripping of the reduced-size profiling airbag 5 being wet all the time.

[0037] As Figures 6-7 shown in the figure, the normally closed valve 8 includes a first valve body 81, first channels 82 opened on the opposite sides of the first valve body 81, first fixing members 83 fixed in the first channels 82, a first gate 84 for opening or closing the left end of the first channel 82, and a linkage structure 85 installed in the first valve body 81; During the process of the first valve body 81 approaching the jet nozzle 73 relatively closely, the left end of the jet nozzle 73 can be accurately inserted into the right end of the first channel 82 under the guidance of the towing rope 72. A seal is provided on the outer side of the left end of the jet nozzle 73 to improve the sealing performance. During this process, the jet nozzle 73 synchronously controls the opening of the first gate 84 through the linkage structure 85, so as to connect the first channel 82 of the first valve body 81 with the jet nozzle 73.

[0038] As Figure 7 shown, the linkage structure 85 includes a second elastic member 851, a connecting rod 852, a push rod 853 and a third elastic member 854. Since the inner and outer sides of the first gate 84 are air and cleaning liquid respectively, a conventional single-opening structure cannot be used. The elastic force of the second elastic member 851 pushes the first gate 84 to close the first channel 82. The moving direction of the first gate 84 is perpendicular to the length direction of the first channel 82. This design can prevent the air and cleaning liquid inside and outside from pushing open the first gate 84; the left end of the connecting rod 852 is fixed to the first gate 84. The length direction of the push rod 853 is the same as the length direction of the first channel 82. The push rod 853 is linearly slidably connected in the first channel 82 in its length direction. The elastic force of the third elastic member 854 pushes the push rod 853 to move away from the first gate 84 under normal conditions. A guiding groove 8531 is provided in the left part of the push rod 853, and the right end of the connecting rod 852 slides relatively in the guiding groove 8531; The guiding groove 8531 includes a straight section and a slope section. Since the profiling airbag 5 inflates inward, there is a situation where the push rod 853 is pushed to move and compress the third elastic member 854. Therefore, a straight section is provided for buffering. During this process, the right end of the push rod 853 always slides within the straight section of the guiding groove 8531 to prevent the first gate 84 from opening; When the jet nozzle 73 is inserted into the first channel 82, the push rod 853 is pushed to move leftward, so that the right end of the push rod 853 relatively moves from the straight section of the guiding groove 8531 to the slope section. The right end of the push rod 853 placed in the slope section pushes the first gate 84 to open the left end of the first channel 84.

[0039] Embodiment 2: Includes all the contents of Embodiment 1: The difference lies in that the normally closed valve 8 includes a second valve body 801, a second valve 802, a fourth elastic member 803 and a second fixing member 804. The second valve 802 closes the outer end of the second channel of the second valve body 801 under the elastic force of the fourth elastic member 803 under normal conditions. The second fixing member 804 is fixed in the second channel of the second valve body 801 and is connected to one end of the towing rope 72; A sealing ring is provided on one side of the second valve 802 close to the second valve body 801 to improve the sealing performance. The right end of the second valve 802 is in linear sliding fit within the second channel of the second valve body 801. The fourth elastic member 803 can be a tension spring, and the elastic force of the tension spring drives the left end of the second valve 802 to close the left end of the second channel under normal conditions; the structure of the second channel is adapted to the free end of the air jet nozzle 73; When the air jet nozzle 73 is relatively inserted into the right end of the second channel, it abuts against the right end of the second valve 802, thereby pushing the left end of the second valve 802 to move relatively leftward away from the second valve body 801, realizing the communication between the second channel of the second valve 802 and the air jet nozzle 73.

[0040] Embodiment 3: An improvement based on Embodiment 1 or Embodiment 2: The difference lies in that: the flexible magnetic strip 52 includes a number of mutually independent magnetic blocks arranged in a line. A row of mutually independent magnetic blocks realizes the formation of a flexible and transformable structure, which is beneficial for storage and does not interfere with normal use; Furthermore, both the rigid magnetic strip 51 and the magnetic blocks adopt an electromagnet structure. When the airbag 5 shrinks, both the rigid magnetic strip 51 and the magnetic blocks lose power and magnetism, avoiding the magnetic attraction between different magnetic strips 51 and magnetic blocks when the airbag shrinks, which may cause difficulty in smooth unfolding.

[0041] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
