Description

Technical Field

[0001] The present invention belongs to the technical field of workpiece processing, and in particular relates to a workpiece processing production system. Background Art

[0002] Currently, in the fields of cleaning, electroplating, and coating, different containers are used to hold different liquids to form the required process flow to complete the cleaning, electroplating, and coating processes on workpieces. For example, to sequentially perform the workpiece degreasing, water washing, pickling, water washing, electroplating, and water washing processes, six containers are required: the first container, the second container, the third container, the fourth container, the fifth container, and the sixth container.

[0003] In addition to the multiple containers mentioned above, traditional equipment for processing workpieces also includes a sliding mechanism arranged directly above the container and a lifting mechanism installed on the sliding mechanism. During the workpiece processing process, the workpiece is first installed on the lifting mechanism, and the lifting mechanism first drives the workpiece to move downward, so that the workpiece extends into the degreasing solution in the first container. After the degreasing process is completed, the lifting mechanism drives the workpiece to move upward and take it out of the first container; thereafter, the sliding mechanism drives the lifting mechanism and the workpiece to move synchronously, so that the workpiece moves from directly above the first container to directly above the second container, and then repeats the above lifting mechanism to drive the workpiece to move downward first, and the workpiece enters the washing solution in the second container. After the washing process is completed, the lifting mechanism takes the workpiece out of the second container again, and the sliding mechanism moves again, so that the lifting mechanism and the workpiece are directly above the third container, and so on, gradually completing the process of the workpiece in the six containers.

[0004] However, when the workpiece processing equipment performs the required processing on the workpiece, the workpiece must be lifted and moved horizontally to transfer the workpiece from one container to another, which makes the equipment inefficient in processing the workpiece. At the same time, the setting of the lifting mechanism and the sliding mechanism makes the equipment structure complex and occupies a large space.

[0005] In order to solve the above technical problems, if the sliding mechanism only moves the workpiece in the horizontal direction, a connecting hole needs to be opened on the adjacent walls of the two adjacent containers. Since the workpiece passes through the connecting hole during the movement from the latter container to the previous container, and since there is always a gap between the connecting hole and the workpiece, the solution in the container will continuously flow out through the connecting hole, causing the liquid level in the container to drop rapidly, affecting the processing effect of subsequent batches of workpieces. Summary of the Invention

[0038] The technical solution provided by the present invention has the following advantages:

[0039] 1. The workpiece processing production system provided by the present invention includes: a transmission line, which carries and transmits workpieces; it is characterized in that the workpieces sequentially enter the following arranged along the conveying direction of the transmission line: a pre-processing device, including at least one first container, and a pre-processing component arranged in the first container to pre-process the surface of the workpiece; a processing device, including at least one second container, an electrochemical treatment component arranged in the second container, and a sealed channel arranged at both ends of the second container; a chemical treatment liquid is provided in the second container, and the workpiece is sealedly input or output into or from the second container through the sealed channel; and a post-processing device, including at least one third container, and a post-processing component arranged in the third container to post-process the surface of the workpiece.

[0040] In the workpiece processing production system of this structure, the workpiece is transmitted in sequence along the pre-processing device, the processing channel and the post-processing device, and sealed channels are set at both ends of the second container on the processing device, so that the sealed channel is sealed and connected to the two adjacent containers, so that at least one workpiece in each workpiece sealed channel slides sealedly in the sealed channel, ensuring that the solutions between the two adjacent containers are not mixed with each other, and, only in the two adjacent workpieces, a small amount of solution existing in the gap between the rear end side of the front workpiece and the front side of the rear workpiece is brought out of the sealed channel, so that the liquid level height of the solution in the rear container along the transmission direction of the sealed channel is reduced by a small amount, thereby achieving a very small reduction in the liquid level height and the solution in the two adjacent containers will not mix; at the same time, the workpiece is transferred from one container to another, and the workpiece is continuously subjected to pre-processing, processing, and post-processing processes, which simplifies the workpiece processing process and facilitates subsequent batch processing of workpieces.

[0041] 2. The workpiece processing production system provided herein further includes at least one jig having a placement cavity for holding at least one workpiece. The jig is in sealed sliding connection with the sealed channel via a sealing member. The provision of such a placement cavity enables batch processing of workpieces, significantly increasing the number of workpieces that can be processed in a single batch. This allows multiple workpieces from the same batch to be processed simultaneously, further improving workpiece processing efficiency.

[0042] 3. In the workpiece processing production system provided by the present invention, the sealing component is a sealing plate mounted on the end of the jig not in contact with the sealing channel, and the sealing plate is in sealing sliding connection with the sealing channel. The provision of the sealing plate can block the sealing channel, thereby enabling the aforementioned continuous workpiece processing process regardless of the workpiece's external structure, while also minimizing the drop in liquid level and preventing mixing of solutions in adjacent containers.

[0043] 4. The workpiece processing production system provided by the present invention, the sealed channel includes: a channel body, including two opposite channel side walls, between which the jig is allowed to pass; and a scraper sealing assembly, which is at least arranged on the channel side walls, and the scraper sealing assembly includes a plurality of scraper seals arranged along the travel direction of the pre-processed workpiece, and the sealing component enters the channel body and is slidingly connected to the scraper seal in a sealing manner.

[0044] In the workpiece processing production system of this structure, when the jig through the channel body is moving, the scraper sealing assembly can block part of the processing liquid from flowing out through the channel body as much as possible, and the workpiece is always sealed and slidably connected to the scraper seal, so that the sealing effect between the two is better, thereby reducing the outflow of processing liquid through the channel body and reducing the outflow speed of the processing liquid.

[0045] 5. The workpiece processing production system provided by the present invention, the sealed channel includes: a channel body, including two opposite channel side walls, which allow the pre-processed workpiece to pass through; and a roller assembly, which is arranged on the channel side wall on at least one side of the channel body, the roller assembly includes a plurality of rotatable sealing rollers arranged along the workpiece conveying direction, and the sealing component enters the channel body and is sealed and rollingly connected to the sealing roller.

[0046] This workpiece processing production system has a sealing roller and a workpiece connected in a sealed manner to prevent the liquid level in the second container from dropping too quickly, thereby facilitating subsequent batch processing of the workpieces. Different workpieces undergo the same process using the same solution in each container, ensuring uniformity of the liquid volume in the container during the electroplating process.

[0047] 6. The workpiece processing production system provided by the present invention, the sealed channel includes: a channel body, which allows the pre-processed workpiece to pass through; at least one synchronous belt assembly, which is arranged in the channel body and can move in a closed loop; a sliding channel for the workpiece to slide is formed between the inner side wall of the synchronous belt assembly and the inner wall of the side opposite to the second container, and at least part of the other side walls of the synchronous belt assembly is in sliding contact with the inner wall of the other side of the second container; the inner wall of the sliding channel can be sealingly slidably connected to the sealing component.

[0048] In a workpiece processing production system of this structure, when a plurality of workpieces continuously slide through the sliding channel along the conveying direction, the inner wall of the sliding channel can slide sealingly on the outer wall of the sealing component, so that the inner side wall of the synchronous belt assembly cooperates with the workpieces to slide and seal the sliding channel, thereby reducing the outflow of solution from the sliding channel to the outside. As the synchronous belt assembly moves in a circular motion, a sliding abutment is formed between the inner side wall of the synchronous belt assembly and the outer wall of the sealing component, reducing the friction between the contact surfaces of the two, thereby extending the service life of the sealing surface formed by the contact surfaces of the two.

[0049] At the same time, the outer wall of the synchronous belt assembly is clearance-fitted or slidingly abutted against the inner wall on the other side of the sealing channel, so that there is a very small gap or no clearance fit between the outer wall of the synchronous belt assembly and the inner wall of the sealing channel, which can block the solution in the first area between the outer wall of the synchronous belt assembly and the inner wall of the sealing channel. Therefore, with the cooperation of the synchronous belt assembly and the workpiece, most of the solution in the sealing channel is blocked in the inner cavity of the container, reducing the outflow of the solution in the container through the inlet end or the inlet end of the sealing channel, slowing down the speed at which the liquid level of the solution in the container drops, and having little impact on subsequent batch processing of workpieces.

[0050] 7. In the workpiece processing production system provided herein, the processing device includes at least one liquid reservoir, disposed in correspondence with the sealed passageway and configured to receive the processing liquid flowing out of the sealed passageway opening. The liquid reservoir is connected to the second container via a liquid level circulation mechanism, which ensures that the liquid level in the second container remains constant.

[0051] The workpiece processing production system of this structure is provided with a circulation mechanism, so that the solution flowing out of the second container is collected and transported back to the second container on the sealed channel side that connects the second container and the post-processing device, thereby ensuring that the liquid level in the second container does not drop, ensuring the consistency of the solution in the second container and the stability of the liquid level of the solution capacity.

[0052] 8. The workpiece processing production system provided by the present invention is characterized in that the jig is driven by a driving mechanism through a hanger to be transmitted along the conveying direction, and the hanger includes at least one hanging member arranged on the driving mechanism; the jig includes a base, the sealing plate and a crossbeam, the sealing plate is arranged on opposite sides of the base, the crossbeam is connected across the sealing plate, and the crossbeam is suitable for hanging on the hanging member. In the workpiece processing production system with this structure, the coordination between the hanging member and the jig facilitates the replacement of the jig itself and the replacement of the workpiece contained in the jig during the process of conveying the workpiece along the conveying direction; at the same time, the hanging hanger can be firmly fixed in the hanger, and the roller plating barrel can also be firmly fixed, so that the switching between roller plating and rack plating can be conveniently realized on the same hanging mechanism, and there is no need to set up two sets of electroplating equipment to perform roller plating and rack plating on the workpiece respectively, which saves the manufacturing cost of the electroplating equipment and saves the space occupied by the electroplating equipment.

[0053] 9. The workpiece handling production system provided by this invention features a drive mechanism fixed within a gantry-type support frame, capable of supporting the greater weight of fixtures and products positioned beneath the drive mechanism. Compared to traditional single-arm support lift structures similar to circular lines, this system offers greater mechanical stability and can support a greater number of products. If necessary, multiple drive mechanisms and corresponding fixtures and products can be arranged side by side to achieve greater production capacity and higher production efficiency per unit time.

[0054] 10. The workpiece processing production system provided by the present invention, wherein the pre-processing device and / or the post-processing device includes at least one immersion mechanism for cleaning the workpiece, and the immersion mechanism includes: an immersion treatment chamber; and a liquid injection unit, which is arranged on the inner wall surface of the immersion treatment chamber; and injects immersion liquid toward the workpiece side. The workpiece processing production system with this structure is used to process the workpiece carried in the fixture. Specifically, the workpiece can be immersed, and the immersion liquid is injected into one side of the workpiece in the form of a water curtain by the liquid injection unit to achieve the purpose of immersing the workpiece. Since the liquid flowing out of the liquid injection unit has a large liquid flow rate, the liquid can flow out in the form of a water curtain toward the workpiece, so the liquid outlet pressure is relatively low. When impacting the fixture or the workpiece, it will not generate a large impact force, thereby preventing a large amount of liquid from splashing out of the immersion treatment chamber.

[0055] 11. The workpiece processing production system provided by the present invention, wherein the post-processing device further includes a drying mechanism for blowing air onto the jig. In the workpiece processing production system of this structure, the setting of the drying mechanism allows the workpiece to be dried near the workpiece output position, thereby ensuring the dryness of the workpiece when it is output. At the same time, through the setting of the above-mentioned drying mechanism, the workpiece in the jig can be turned over while being dried, thereby increasing the drying efficiency of the workpiece and saving the drying time of the workpiece; at the same time, when drying a workpiece with holes, if the jig can be rotated and turned, the processing liquid in the workpiece hole can be dumped during the turning process. The setting of the drying device can further increase the drying efficiency of the workpiece.

[0056] 12. In the workpiece processing production system provided herein, the exhaust device is connected to at least one of the processing devices and / or the processing device to exhaust escaping gases within any of the processing devices and / or the processing device. The provision of the exhaust device ensures the collection and centralized discharge of exhaust gases generated during workpiece processing, preventing direct discharge of exhaust gases into the environment, thus meeting environmental protection requirements.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0092] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0093] Example 1

[0094] This embodiment provides a workpiece processing production system, such as Figures 1 to 12 As shown, it includes: a ring-shaped transmission line 1, and the workpieces sequentially enter the following devices arranged along the conveying direction of the transmission line 1: a loading position, a pre-processing device, a processing device 3, a post-processing device 4 and a unloading position.

[0095] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, a jig 2 supports the workpiece on a conveyor line 1, and the jig 2 is driven by a drive mechanism along the conveying direction via a sling. The pre-treatment device includes at least one first container 6 and a pre-treatment component disposed within the first container 6 to pre-treat the workpiece surface. The processing device 3 includes at least one second container 31, an electrochemical treatment component 32 disposed within the second container 31, and sealed channels 33 disposed at both ends of the second container 31. The second container 31 contains a chemical treatment solution, and the workpiece is sealedly transported into and out of the second container 31 through the sealed channels 33. The post-treatment device 4 includes at least one third container 41 and a post-treatment component disposed within the third container 41 to post-treat the workpiece surface. In this embodiment, the loading and unloading stations are located at the same location, facilitating operator convenience during loading and unloading. For example, the first container 6 can contain an acid pickling solution, as well as an acid pickling component and a water washing component, to perform pre-treatment procedures such as pickling on the workpiece. The second container 31 contains an electroplating solution. Alternatively, for electrolysis operations, the second container 31 can also contain an electrolyte. The third container 41 contains a passivation component, a light output component, a water washing component and an air drying mechanism to achieve post-processing of the workpiece surface.

[0096] like Figure 1 and Figure 2 As shown, the driving mechanism includes a conveyor belt 11 and a driving assembly that drives the conveyor belt 11 to move; the top of the fixture 2 is fixed on the conveyor belt 11. The conveyor belt 11 can be optionally a chain, which is a closed loop. The driving assembly includes a driving wheel 13, a passive wheel 14 and a motor 12 that drives the driving wheel 13 to rotate. The chain is closed and arranged around the outer periphery of the driving wheel 13 and the passive wheel 14. The driving wheel 13 is driven to rotate by the rotation of the motor 12, thereby driving the chain to move and then driving the passive wheel 14 to rotate. The driving mechanism is fixed in the gantry-type support frame 16, so it can bear more weight of the fixtures and products arranged under the driving mechanism. Compared with the traditional single-arm support lifting structure similar to the circular line, it has higher mechanical stability and can carry more products. If necessary, multiple driving mechanisms and corresponding fixtures and products can be arranged side by side to achieve greater production capacity and higher production efficiency per unit time.

[0097] like Figure 4As shown, in this embodiment, the hanger includes a hanger 15 mounted on a drive mechanism; the jig 2 includes a base 22, a sealing plate 21, a crossbeam 23, a conductive shaft 24, a conductive disc 25, and an open drum. The sealing plates 21 are mounted on opposite sides of the base 22, and the crossbeam 23 bridges and connects the sealing plates 21. The crossbeam 23 is adapted to be mounted on the hanger 15. The conductive shaft 24 is mounted on the sealing plates 21 on either side; the conductive disc 25 is sleeved on the conductive shaft 24. The pulley of the open drum is wound around the conductive disc 25, and the conductive disc 25 and the inner cavity of the pulley form a placement cavity for the workpiece. In this embodiment, the open drum is a barrel plating drum with an opening on one side. It rotates, and in turn, the workpiece in the placement cavity rotates, thereby increasing the uniformity of contact between the workpiece and the solution in the container and improving the workpiece processing process. When the drive mechanism drives the jig 2 along the conveying direction, the jig 2 is sealed and slidably connected to the sealing channel 33 via the sealing plate 21. The arrangement of the aforementioned placement chamber allows batch processing of workpieces, significantly increasing the number of workpieces that can be processed in a batch, thereby allowing multiple workpieces from the same batch to be processed simultaneously, further improving workpiece processing efficiency. The arrangement of the aforementioned sealing plate 21 can block the sealing channel 33, thereby enabling continuous workpiece processing regardless of the workpiece's external structure. Furthermore, the arrangement of the aforementioned sealing plate 21 allows for minimal reduction in the liquid level, preventing mixing of solutions in adjacent containers.

[0098] For ease of explanation, it is assumed that, except for the two ends of the second container, the rear end of the first container 6 and the front end of the third container are both provided with sealed channels, that is, the starting end of the first container 6 and the terminal outlet wall of the third container 41 are not provided with sealed channels 33. There are a total of four sealed channels 33 on the three containers. Figure 3 Take the schematic structure as an example.

[0099] like Figure 5 and Figure 8 As shown, in this embodiment, each sealing channel is a raised structure provided on the sidewall of the container, projecting in the direction of the fixture. For example, its cross-section can be an isosceles trapezoidal structure. The long side of the isosceles trapezoid is mounted on the inner sidewall of the container, while the short side of the isosceles trapezoid slides in a sealed manner with the fixture. The short side of the isosceles trapezoid serves as a sliding channel, i.e., the portion of the sealing channel that actually contacts the fixture.

[0100] In this embodiment, in the conveying direction, the distance between any two adjacent sealing plates 21 is L1 i , the length of any sliding channel is L0 i , the above L1 i With L0 i Between: L0 min ≥L1 max Among them, L1max For all L1 i The maximum value in L0 min is the minimum value among all L0i, and i is a natural number greater than or equal to 1. L1 i With L0 i Set between to meet L0 min ≥L1 max The relationship between the liquid level of the solution in the container can be reduced to a small extent, ensuring the continuity of workpiece processing.

[0101] Specifically, in the horizontal direction of the movement of the sealing plate 21, as shown in FIG. Figure 6a As shown, the distance between any two adjacent sealing plates 21 is L1 i , the length of any sliding channel is L0 i , where L1 i With L0 i Between: L0 min ≥L1 max , where L1 max For all L1 i The maximum value in L0 min For all L0 i , and i is a natural number greater than or equal to 1.

[0102] For example, there are 10 fixtures on the transmission line, and the corresponding sealing plates 21 are 20 (one sealing plate is located on the front and rear sides of the fixture). The distances between two adjacent sealing plates 21 are L11, L12, L13, L1, L15, L16, L17, L18, L19, L1 10 , then L1 max (L11, L12, L13, L1, L15, L16, L17, L18, L19, L1 10 ), for example, L13 is the maximum value, then L1 max = L13; Correspondingly, since the 10 fixtures are arranged in a circular manner, or the circular manner is opened and arranged linearly, for the convenience of explanation and illustration, the linear arrangement is used for illustration. The lengths of the four sliding channels in this embodiment are L01, L02, L03, and L0 respectively, then L0 min is the minimum value among (L01, L02, L03, L0), for example, L0 is the minimum value, then L0 min =L0, and finally L0≥L13.

[0103] When jigs are continuously introduced into the starting entry end of any container, several jigs are continuously moved forward horizontally along with the sealing plate 21. i With L0 iThe above relationship is satisfied, and each sliding channel has the following states (not limited to the following states). The following example takes the case where the length of each sliding channel is equal and the distance between any two adjacent sealing plates 21 is equal.

[0104] The first state: when L0 min =L1 max When , in the two adjacent fixtures, at this time, if Figure 6a As shown, due to L0 min =L1 max , the sealing plate 21 at the rear side of the front fixture and the sealing plate 21 at the front end of the rear fixture are respectively blocked at the outlet and inlet ends of a sliding channel, sealing the two ends of the sliding channel so that the inner cavity of the sliding channel is separated from the inner cavity of the container in which it is located; if the sealing plate 21 continues to move forward, such as Figure 6b As shown, the front sealing plate 21 of the rear fixture enters the sliding channel and slides in a sealed manner, thereby sealing the sealing channel. If it continues to move forward, as shown in FIG. Figure 6c As shown, the front sealing plate 21 of the rear fixture is just moved to the exit of the sliding channel. At this time, the upper sealing plate 21 at the rear end of the fixture is just blocked at the entrance of the sliding channel, so that there is at least one sealing plate 21 in each sliding channel, or a sealing plate 21 is blocked at the entrance and exit of the sliding channel respectively to seal the sealing channel 33. Similarly, a sealing channel is sealed.

[0105] The second state: when L0 min >L1 max When, such as Figure 6d As shown, in the two adjacent fixtures, the sealing plate 21 on the rear end of the front fixture and the sealing plate 21 on the front end of the rear fixture are both located in the same sliding channel and slide in a sealed manner, forming two sliding sealed partition walls in the sliding channel; if the sealing plate 21 continues to move forward, when the front fixture is removed from the sliding channel, the front end sealing plate 21 of the rear fixture slides in a sealed manner in the sliding channel, and if the rear fixture continues to move forward, it plays a role in sealing and partitioning between the sliding channel and the inner cavity of the container. Or as Figure 6e As shown, the front sealing plate 21 of the jig has just moved out of the sliding channel, and at least a portion of the rear sealing plate 21 of the jig has entered the sliding channel for sealing and sliding.

[0106] Therefore, there is at least one sealing plate 21 in each sliding channel that slides sealedly in the sliding channel, or is sealed and blocked by a sealing plate 21 at the inlet and outlet of the sliding channel, so that the inner cavity of the sliding channel is sealed and separated from the inner cavity of the container in which the sliding channel is located, preventing the solution in the container from continuously entering the sliding channel; only in two adjacent fixtures, there is a small amount of solution in the gap between the sealing plate 21 at the rear end of the front fixture and the sealing plate 21 at the front end of the rear fixture, and a small amount of solution in the gap between the two sealing plates 21 at both ends of the same fixture, which is carried out of the sliding channel, so that the liquid level height of the solution in the container is reduced by a small amplitude, and then the fixture can be continuously driven to move by moving the sealing plate 21 horizontally, and the solutions in the two adjacent containers will not mix. The fixture is transferred from one container to another, and the workpiece in the fixture is continuously processed in different processes, which simplifies the workpiece processing process and facilitates subsequent batch processing of workpieces.

[0107] like Figure 7 As shown, the processing device 3 includes, in addition to the two second containers 31 and the electrochemical treatment component 32, a liquid storage tank 34 and a liquid level circulation mechanism. Figure 8 、 Figure 9 and Figure 10 As shown, a liquid reservoir 34 is provided corresponding to the sealed passage 33 to receive the treatment liquid flowing out of the opening of the sealed passage 33. The liquid reservoir 34 is connected to the second container 31 via a liquid level circulation mechanism, which ensures that the liquid level in the second container 31 remains constant. For example, in this embodiment, the processing device 3 has two interconnected liquid reservoirs 34, which are connected by a connecting pipe. The liquid level circulation mechanism includes a circulation pump 35 and an overflow channel 36. The circulation pump 35 replenishes the treatment liquid in the liquid reservoir 34 into the second container 31. The overflow channel 36 is connected to the second container 31 and the liquid reservoir 34 at both ends. By providing the circulation mechanism, the solution flowing out of the second container 31 is collected on the side of the sealed passage 33 connecting the second container 31 with the post-processing device 4 and re-transferred to the second container 31, thereby ensuring that the liquid level in the second container 31 does not drop, and that the consistency of the solution in the second container 31 and the stability of the liquid level are maintained.

[0108] like Figure 11As shown, in this embodiment, both the pre-treatment device and the post-treatment device have an immersion mechanism for cleaning the workpiece, and the immersion mechanism includes: an immersion treatment chamber 421 and a liquid injection unit. Specifically, the liquid injection unit is arranged on the inner wall surface of the immersion treatment chamber 421; and injects immersion liquid toward the workpiece side. In this embodiment, the injection unit has a first liquid outlet 423 arranged on the side wall of one side of the immersion treatment chamber 421, and a second liquid outlet 424 on the other opposite side wall of the immersion treatment chamber 421. The liquid outflow rate of the first liquid outlet 423 is greater than the liquid discharge rate of the placement chamber of the fixture 2 for accommodating the workpiece, and the liquid outflow rate of the second liquid outlet 424 can be less than the liquid outflow rate of the first liquid outlet 423. For example, when performing an immersion reaction on a workpiece in a placement chamber, the opening side of the placement chamber of the jig 2 for accommodating the workpiece is oriented toward the first liquid outlet 423. The treatment liquid flowing out of the first liquid outlet 423 can enter the placement chamber of the jig 2 for accommodating the workpiece. Since the discharge flow rate of the placement chamber is less than the outflow flow rate of the first liquid outlet 423, a certain water level can be formed in the placement chamber, thereby performing an immersion reaction on the workpiece. Since the second liquid outlet 424 is used to clean the back of the jig 2 during cleaning, it requires a smaller flow rate of rinse liquid, which can reduce its outflow rate, thereby saving power output at the liquid output end of the liquid injection unit and saving energy. For example, a delivery pump 422 can be used as the liquid output end.

[0109] On the side wall of the immersion treatment chamber 421, there is a vertically arranged liquid outlet channel 425, one end of the liquid outlet channel 425 is connected to the liquid outlet, and the other end is used to connect to the outlet of the delivery pump 422; arranging the liquid outlet channel 425 on the side wall can reduce the layout of the pipeline, making the overall equipment more simple; because the liquid flowing out of the liquid injection unit has a large liquid outlet flow rate, the liquid can flow out in the form of a water curtain toward the workpiece, so the liquid outlet pressure is relatively small, and when it impacts the fixture or workpiece, it will not generate a large impact force, thereby preventing a large amount of liquid from splashing out of the immersion treatment chamber; because it is arranged vertically, it can reduce the discharge pressure of the delivery pump 422, so that the liquid flowing out of the liquid outlet has a large flow rate and a low pressure, thereby further allowing the liquid flowing out of the liquid outlet to present the form of a water curtain. In addition, as an alternative embodiment, the liquid outlet channel 425 can be not arranged on the side wall, for example, it can be replaced by a conventional liquid supply hose.

[0110] like Figure 12 As shown, the post-processing device also includes a drying mechanism for blowing air toward the jig 2. The drying mechanism includes an air drying chamber and a gas injection unit. The gas injection unit is located on the inner wall of the air drying chamber and is used to inject air toward the jig 2.

[0111] This embodiment provides a specific implementation of a workpiece drying device, such as Figure 12As shown, it includes: an air drying chamber and a gas injection unit. The gas injection unit has an air source 434 that blows hot air into the air drying chamber. The gas injection unit includes an air blowing port, an air blowing channel 433 and an air source 434.

[0112] like Figure 12 As shown, the air drying chamber has two opposing walls. When the jig 2 passes through, the air outlets on the two walls blow hot air to dry the workpiece and the jig 2, thereby removing any residual post-processing liquid from the workpiece and the jig 2.

[0113] Specifically, the blowing port has a first blowing port 431 and a second blowing port 432, and the first blowing port 431 and the second blowing port 432 are respectively arranged on two opposite side walls in the air-drying treatment tank. When the workpiece and the jig 2 carrying the workpiece are accommodated in the air-drying channel, the nozzle of the first blowing port 431 sprays toward the opening side of the jig 2 placement cavity, and the blowing flow rate of the second blowing port 432 is less than the blowing flow rate of the first blowing port 431. That is, the first blowing port 431 is used to blow dry the workpiece accommodated in the jig 2 and the front of the jig 2, so its blowing volume is set to be larger to ensure the drying effect; while the second blowing port 432 is used to blow dry the back of the jig 2, and the required blowing volume is smaller, so its blowing volume can be appropriately reduced, which can save the power output of the wind source 434 and save energy. In addition, as an alternative embodiment, the air flow rate of the second air outlet 432 may not be reduced, and the air volume of the air outlets may be connected to each other through the size of the air outlet opening.

[0114] A blowing channel 433 is provided on the side wall of the air-drying chamber. One end of the blowing channel 433 is connected to the blowing port, and the other end is connected to an air source 434. Placing the blowing channel 433 on the side wall reduces piping requirements, making the overall apparatus more streamlined. Alternatively, the blowing channel 433 can be replaced with a conventional air supply hose, for example. Because the fixture is a barrel, and the workpiece-holding chamber of the barrel is open on one side, the blowing port located on one side of the workpiece drying device can directly blow air toward the workpiece through the opening of the chamber. Furthermore, while blowing air toward the workpiece through the blowing port, the barrel can tumble the workpiece, allowing it to tumble and be blown simultaneously, improving drying efficiency. The bottom of the barrel is provided with multiple evenly spaced drainage holes, through which the reaction liquid in the chamber and the reaction liquid flowing out of the workpiece during tumbling can flow downward. A post-processing liquid storage chamber is connected to the air-drying chamber below. The liquid flowing out of the barrel plating barrel during post-processing can enter the post-processing liquid storage chamber for recovery. A pump inlet is provided at the bottom of the post-processing liquid storage chamber. The pump can be driven to recover the post-processing liquid into the container of the previous process, thereby reducing the consumption of post-processing liquid.

[0115] The workpiece processing production system in this embodiment, such as Figure 1 、 Figure 7 and Figure 9 As shown, it also includes an exhaust device 5. The exhaust device 5 is interconnected with the pre-processing device, the processing device 3 and the post-processing device 4 to exhaust the escaped gas.

[0116] In this embodiment, the exhaust device 5 includes: an exhaust port 51, an exhaust channel 52 and a negative pressure source. The exhaust port 51 is formed on the side wall of any container; the negative pressure source is connected to the exhaust port 51. Specifically, the negative pressure source is a negative pressure generator, and the negative pressure generator is interconnected with the exhaust port 51 through a pipe. The exhaust channel 52 is a horizontal pipe arranged in the middle of the circular production line, and a longitudinal pipe that is interconnected with the rear side walls of all containers respectively; in the second container 31, the height of the exhaust port 51 is higher than the height of the overflow port 37. Since evaporation mostly occurs at the interface between liquid and gas, the exhaust port 51 that is higher than the height of the overflow port 37 can ensure centralized treatment of escaping gas.

[0117] In the workpiece processing production system provided in this embodiment, the workpiece is transmitted in sequence along the pre-processing device, the processing channel and the post-processing device 4, and a sealing channel 33 is set at both ends of the second container 31 on the processing device 3, so that the sealing channel 33 is sealed and connected to the two adjacent containers, so that there is at least one workpiece in each workpiece sealing channel 33 and slides sealedly in the sealing channel 33, ensuring that the solutions between the two adjacent containers are not mixed with each other, and, only in the two adjacent workpieces, a small amount of solution existing in the gap between the rear end side of the front workpiece and the front side of the rear workpiece is brought out of the sealing channel 33, so that the liquid level height of the solution in the rear container of the sealing channel 33 along the transmission direction is reduced by a small amount, thereby achieving a very small reduction in the liquid level height and the solution in the two adjacent containers will not be mixed; at the same time, the workpiece is transferred from one container to another, and the workpiece is continuously subjected to pre-processing, processing, and post-processing processes, simplifying the workpiece processing process and facilitating subsequent batch processing of workpieces.

[0118] Example 2

[0119] This embodiment provides a workpiece processing production system. Compared with the workpiece processing production system provided in Example 1, the difference between the present embodiment and the workpiece processing production system is that the sealing channel 33 has a different structure:

[0120] like Figure 13 and Figure 14 As shown, in this embodiment, the sealed channel 33 comprises a channel body 331 and a scraper seal assembly. The channel body 331 includes two opposing channel sidewalls, between which the jig 2 can pass. The scraper seal assembly is located on the channel sidewalls and includes multiple scraper seals 3321 positioned along the direction of travel of the pre-processed workpiece. The sealing component enters the channel body 331 and is in sealing sliding engagement with the scraper seals 3321. Alternatively, the channel body may be provided with three sets of scraper seals 3321, one on each of the sidewalls and the bottom wall.

[0121] The scraper seal assembly in this embodiment includes multiple scraper seals 3321 and multiple sets of sealing fixtures. The scraper seals 3321 are positioned along the conveying direction of the jig 2 and are removably attached to the inner wall of the channel body 331 via sealing fixtures. As the jig 2 passes through the channel body 331, the scraper seal assembly minimizes the outflow of process fluid through the channel body 331. Furthermore, the workpiece maintains a sealed sliding connection with the scraper seals 3321, ensuring a good seal between the two. This reduces the outflow of process fluid through the channel body 331 and reduces the outflow rate of the process fluid.

[0122] Among them, the scraper seal 3321 in this embodiment is set to a flexible material, and the specific material can be made of rubber material or other flexible materials. The scraper seal 3321 is set to be inclined toward the workpiece conveying direction, so as to minimize the resistance encountered by the sealing plate 21 during the movement, which is conducive to the smooth passage of the sealing plate 21 through the channel body 331. By setting the scraper seal 3321 to be detachable, it is convenient to replace and adjust the scraper seal 3321. By setting it as a flexible scraper seal 3321, when the jig 2 passing through the channel body 331 shakes during the movement, the scraper seal 3321 of the flexible material can always be slidably connected with the sealing plate 21 in a sealed manner, and at the same time, the wear between the flexible scraper seal 3321 and the sealing plate 21 can also be reduced.

[0123] In this embodiment, the sealing fixture includes a first sealing fixture 3322, a second sealing fixture 3323 and a connecting piece. The first sealing fixture 3322 can be fixed on the inner wall surface of the channel body 331 by welding or other connection methods. The scraper seal 3321 is located between the second sealing fixture 3323 and the first sealing fixture 3322. The connecting piece such as a screw fixes the second sealing fixture 3323, the scraper seal 3321 and the first sealing fixture 3322.

[0124] When the jig 2 is moving, the end of the scraper seal 3321 just abuts against the sealing plate 21; or if the scraper seal 3321 is longer, the scraper seal 3321 is bent by the sealing plate 21, and part of the side of the scraper seal 3321 is in contact with the sealing plate 21, that is, the scraper seal 3321 has a bending length that is in contact with the sealing plate 21 when it is bent by the sealing plate 21. At this time, the bending length of the scraper seal 3321 needs to be less than or equal to the distance between adjacent scraper seals 3321 to ensure the smooth movement of the jig 2.

[0125] In the above-mentioned sealing channel, since the length of the sliding channel in Example 1 is the actual effective sealing length between the sealing roller and the fixture in this embodiment, in this embodiment, the actual length of the sliding channel is the same as that of the channel body.

[0126] Example 3

[0127] This embodiment provides a workpiece processing production system. Compared with the workpiece processing production system provided in Example 1 or Example 2, the difference is that the sealing channel 33 has a different structure:

[0128] like Figure 15 、 Figure 17 and Figure 18As shown, specifically, the sealing channel 33 includes: a channel body 331 and a roller assembly. The channel body 331 includes two opposite channel side walls, which allow the fixture 2 to pass through; the roller assembly is provided on the channel side walls on both sides of the channel body 331. The roller assembly includes a plurality of rotatable sealing rollers 3331 arranged along the workpiece conveying direction. The sealing component enters the channel body 331 and is sealed and rollingly connected with the sealing rollers 3331. Of course, as Figure 16 As shown, three sets of sealing rollers can also be provided on the channel body, respectively on the two side walls and the bottom wall.

[0129] In this embodiment, the roller assembly includes a first transmission member 3332, a second transmission member 3334, a rotating shaft 3333, a driving member, and multiple sealing rollers 3331. The first transmission member 3332 and the second transmission member 3334 are arranged in a transmission arrangement. The first transmission member 3332 is mounted on the outer side of the rotating shaft 3333, while the second transmission member 3334 is mounted on top of the sealing rollers 3331. The rotating shaft 3333 and the driving member are fixedly connected to each other. Specifically, the driving member is a rotary motor. The sealing rollers 3331 are elastic rollers made of sponge rollers mounted on the outer side of the rotating shaft 3335. Alternatively, elastic materials such as rubber can be used. As long as the sealing rollers 3331 can be resiliently returned to their original position after being squeezed by the jig 2, the first transmission member 3332 and the second transmission member 3334 are meshing gears. When the rotary motor rotates, it drives the first transmission member 3332 and the second transmission member 3334 to rotate, which in turn drives the sealing rollers 3331 to rotate.

[0130] During the workpiece processing process, the sealing plate 21 is sealed and rollingly connected to the outer peripheral surface of the elastic sealing roller 3331, wherein the workpiece to be processed is carried by the jig 2 and moves within the channel body 331. Specifically, the jig 2 is driven by the driving mechanism on the processing equipment to move within the channel body 331. The rotation direction of the sealing roller 3331 is the same as the travel direction of the workpiece. The elastic sealing roller 3331, driven by the driving member, provides a forward compensation force to the sealing roller 3331. This force, together with the driving force that drives the jig 2 forward, enables the jig 2 carrying the workpiece to be processed and output efficiently and stably. In the above-mentioned sealed channel, since the length of the sliding channel in Example 1 is the actual effective sealing length between the sealing roller and the jig in this embodiment, in this embodiment, the sliding channel is the difference between the length of the channel body and the diameter of one sealing roller.

[0131] Example 4

[0132] This embodiment provides a workpiece processing production system. Compared with any of the workpiece processing production systems provided in Embodiments 1 to 3, the difference between the present embodiment and the present embodiment is that the structure of the sealing channel 33 is different:

[0133] like Figure 19 As shown, the sealed channel 33 includes: a channel body 331 and a synchronous belt assembly. The channel body 331 allows the pre-processed workpiece to pass through; the synchronous belt assembly is located within the channel body 331 and can move in a closed loop; the inner side wall of the synchronous belt assembly and the inner wall of the side opposite the second container 31 form a sliding channel for the workpiece to slide, and at least a portion of the other side wall of the synchronous belt assembly forms a sliding abutment with the other inner wall of the second container 31; the inner wall of the sliding channel can be sealingly slidably connected to the sealing component. Of course, the channel body can also be equipped with three sets of synchronous belt assemblies, one on each side wall and the bottom wall, to further achieve the purpose of sealed sliding of the jig within the sealed channel.

[0134] For example, the synchronous belt assembly has a synchronous belt body 3341 that is arranged to rotate along the conveying direction, and the synchronous belt body 3341 is arranged to rotate under the driving wheel 3342. In the above-mentioned sealing channel, since the length of the sliding channel is the actual effective sealing length between the synchronous belt body 3341 and the jig in the horizontal direction in this embodiment, the sliding channel in this embodiment is the difference between the length of the channel body and the diameter of one driving wheel 3342. The jig 2 can also be sealed and slid in the sliding channel. When several jigs continuously slide through the sliding channel along the conveying direction, since the inner wall of the sliding channel can be sealedly slid on the outer wall of the sealing component, the inner side wall of the synchronous belt assembly cooperates with the workpiece to slide and seal the sliding channel, thereby reducing the outflow of the solution from the sliding channel to the outside; since the synchronous belt assembly is moving in a cycle, a sliding abutment is formed between the inner side wall of the synchronous belt assembly and the outer wall of the sealing component, thereby reducing the friction between the contact surfaces of the two, and making the sealing surface formed by the contact surfaces of the two have a long service life;

[0135] At the same time, the outer wall of the synchronous belt assembly is clearance-fitted or slidingly abutted against the inner wall of the other side of the sealing channel 33, so that there is a very small gap or no clearance fit between the outer wall of the synchronous belt assembly and the inner wall of the sealing channel 33, which can block the solution in the first area between the outer wall of the synchronous belt assembly and the inner wall of the sealing channel 33. Therefore, with the cooperation of the synchronous belt assembly and the workpiece, most of the solution in the sealing channel 33 is blocked in the inner cavity of the container, reducing the outflow of the solution in the container through the inlet end or the inlet end of the sealing channel 33, slowing down the speed at which the liquid level of the solution in the container drops, and having little impact on the subsequent batch processing of workpieces.

[0136] Example 5

[0137] This embodiment provides a workpiece processing production system. Compared with any of the workpiece processing production systems provided in Examples 1 to 4, the present embodiment has the following differences: two annular transmission lines 1 are provided, and the two annular transmission lines 1 are placed in two inner and outer circles, such as Figure 20 As shown, both conveyor lines are provided with jigs 2 , and the jigs 2 on the conveyor lines are arranged to be transmitted along the conveying direction of the transmission line 1 .

[0138] Example 6

[0139] This embodiment provides a workpiece processing production system, which is different from any of the workpiece processing production systems provided in Examples 1 to 5 in that: the electroplating method is changed by changing the structure of the fixture;

[0140] The electroplating treatment of the workpiece is achieved by adopting the rack plating method. By not setting the conductive shaft 24, the conductive disk 25 and the open drum in the fixture, a hook is directly set to hang the workpiece or the workpiece is directly suspended, thereby achieving the drum plating of the workpiece.

[0141] It is worth noting that when the workpiece is directly suspended, the sealing plates can be directly installed at both ends of the workpiece. Of course, the sealing plates can also be omitted, and the two ends of the workpiece itself can be directly sealed with the sealing channel.

[0142] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
