Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surface treatment, in particular to a transfer conveying system for part surface treatment. BACKGROUND

[0002] In modern industrial production, part surface treatment is an important process link to improve the corrosion resistance, wear resistance and appearance quality of parts. Among them, black oxidation treatment and electroplating treatment are two common surface treatment methods. Black oxidation treatment usually immerses the parts into the blackening solution in the blackening tank to form a dense oxide film on the surface of the parts, thereby improving the corrosion resistance and appearance quality of the parts. Electroplating treatment is to deposit a metal plating layer on the surface of the parts by electrochemical method to enhance the wear resistance and decorative properties of the parts.

[0003] However, the existing surface treatment system has many inconveniences when switching the treatment process. For example, when a batch of parts is subjected to black oxidation treatment, the batch of parts needs to be conveyed to the blackening tank loaded with blackening solution. If part of the batch of parts needs to be subjected to electroplating treatment, the blackening solution in the blackening tank must be emptied first, and then the part of the parts is conveyed to the station where the blackening tank is located for electroplating treatment. After the part of the parts is subjected to electroplating treatment, the blackening solution needs to be refilled in the blackening tank for subsequent black oxidation treatment of the parts. Such repeated switching operation not only increases the complexity of the process flow, but also leads to low production efficiency, low equipment utilization, and increases the production cost and the risk of operation errors. SUMMARY

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] In modern industrial production, part surface treatment is an important process link to improve the corrosion resistance, wear resistance and appearance quality of parts. Among them, black oxidation treatment and electroplating treatment are two common surface treatment methods. Black oxidation treatment usually immerses the parts in the blackening solution in the blackening tank to form a dense oxide film on the surface of the parts, thereby improving the corrosion resistance and appearance quality of the parts. Electroplating treatment is to deposit a layer of metal plating on the surface of the parts by electrochemical method to enhance the wear resistance and decorative properties of the parts.

[0042] However, the existing surface treatment system has many inconveniences when switching the treatment process. For example, when a batch of parts is subjected to black oxidation treatment, the batch of parts needs to be transported to the blackening tank loaded with blackening solution. If part of the batch of parts needs to be subjected to electroplating treatment, the blackening solution in the blackening tank must be emptied first, and then the part of the parts is transported to the station where the blackening tank is located for electroplating treatment. After the part of the parts is subjected to electroplating treatment, the blackening solution needs to be filled in the blackening tank again for subsequent black oxidation treatment of the parts. Such repeated switching operation not only increases the complexity of the process flow, but also leads to low production efficiency, low equipment utilization, and increases the production cost and the risk of operation failure.

[0043] In order to solve the above problems, the present application provides a transfer conveying system for part surface treatment, which aims to integrate black oxidation equipment and electroplating equipment into one system, and guide the parts on the conveying line to the black oxidation equipment or the electroplating equipment through the blocking action of the shunt baffle. In this way, black oxidation treatment or electroplating treatment can be flexibly selected for the corresponding batch of parts according to actual needs, without repeated blackening solution filling and emptying operation of the blackening tank in the black oxidation equipment, thereby simplifying the process, improving the equipment utilization and production efficiency, and reducing the production cost and the risk of operation failure.

[0044] Please refer to Figure 1 and Figure 2 , the present application provides a transfer conveying system for part surface treatment, comprising:

[0045] The first conveying line 1 is used to convey the parts to be treated from the front end to the rear end;

[0046] The first channel 2 is connected with the rear end of the first conveying line 1, and the rear end of the first channel 2 is used to connect the black oxidation equipment 5;

[0047] The second channel 3 is connected with the rear end of the first conveying line 1, and the end of the second channel 3 is used to connect the electroplating equipment 6;

[0048] The shunt baffle 4 is rotatably connected to the connecting node between the rear end of the first conveying line 1, the front end of the first channel 2, and the head end of the second channel 3; when the shunt baffle 4 is rotated to the first working position, the shunt baffle 4 forms a blocking action between the rear end of the first conveying line 1 and the head end of the second channel 3, so as to guide the parts on the first conveying line 1 to the first channel 2; when the shunt baffle 4 is rotated to the second working position, the shunt baffle 4 forms a blocking action between the rear end of the first conveying line 1 and the front end of the first channel 2, so as to guide the parts on the first conveying line 1 to the second channel 3.

[0049] In the embodiment, the first conveying line 1 can adopt a common conveying belt or conveying chain structure to place the parts to be conveyed. The first channel 2 can also be provided with a corresponding conveying belt or conveying chain structure to convey the parts to be processed entering the front end of the first channel 2 to the black oxidation equipment 5 at the rear end for black oxidation processing; similarly, the second channel 3 can also be provided with a corresponding conveying belt or conveying chain structure to convey the parts to be processed entering the head end of the second channel 3 to the electroplating equipment 6 at the tail end for electroplating processing.

[0050] It should be noted that the front end of the first conveying line 1 is located in front of the rear end of the first conveying line 1, the front end of the first channel 2 is located in front of the rear end of the first channel 2, and the head end of the second channel 3 is not necessarily located in front of the tail end of the second channel 3.

[0051] The shunt baffle 4 can be rotatably connected to the junction area between the rear end of the first conveying line 1, the front end of the first channel 2, and the head end of the second channel 3 through a corresponding hinged structure. The shunt baffle 4 can be rotated to at least the first working position and the second working position; when the shunt baffle 4 is rotated to the corresponding working position, the shunt baffle 4 can be limited by the buckle structure to prevent the shunt baffle 4 from continuing to rotate and keep it at the current angle position.

[0052] When the shunt baffle 4 is rotated to the first working position, the shunt baffle 4 forms a blocking action between the rear end of the first conveying line 1 and the front end of the second channel 3, so that the parts to be processed at the rear end of the first conveying line 1 can only enter the front end of the first channel 2, and then enter the black oxidation equipment 5 through the first channel 2 for black oxidation treatment. Conversely, when the shunt baffle 4 is rotated to the second working position, the shunt baffle 4 forms a blocking action between the rear end of the first conveying line 1 and the front end of the first channel 2, so that the parts to be processed at the rear end of the first conveying line 1 can only enter the front end of the second channel 3, and then enter the electroplating equipment 6 through the second channel 3 for electroplating treatment. The relative position arrangement form between the shunt baffle 4 and the first conveying line 1, the first channel 2 and the second channel 3 can be flexibly set according to actual needs, which is not limited here. For example, the junction between the rear end of the first conveying line 1, the front end of the first channel 2 and the front end of the second channel 3 can be set as a three-way structure on the horizontal plane, and one side of the shunt baffle 4 can be rotatably connected between the front end of the first channel 2 and the front end of the second channel 3 about a vertical axis. In this way, by rotating the shunt baffle 4, the shunt baffle 4 can be blocked at the front end of the first channel 2 or at the front end of the second channel 3.

[0053] In actual application, the shunt baffle 4 can be rotated by manual operation or automatic control system. For example, as shown in Figure 1 , a handle structure 13 can be installed on the shunt baffle 4, and the operator can conveniently drive the shunt baffle 4 to rotate to the first working position or the second working position by pulling the handle structure 13 under the action of the lever. In addition, the shunt baffle 4 can also be driven to rotate by a motor or other driving device, and the automatic switching of the shunt baffle 4 in different working positions can be realized through signal transmission control between the sensor, the controller and the driving device. The automatically driven shunt baffle 4 not only can improve the switching speed, but also can reduce human operation errors, and can improve the automation and intelligence of the transfer conveying system.

[0054] As can be seen, the transfer conveying system for part surface treatment provided in the embodiment integrates the black oxidation equipment 5 and the electroplating equipment 6 into one system, and guides the parts to be processed on the conveying line to the black oxidation equipment 5 or the electroplating equipment 6 through the blocking action of the shunt baffle 4, so that the black oxidation treatment or electroplating treatment can be flexibly selected for the corresponding batch of parts to be processed according to actual needs, without the complicated black solution injection and discharge operation of the blackening tank in the black oxidation equipment 5, thereby simplifying the process flow, improving the equipment utilization and production efficiency, and reducing the production cost and the risk of operation errors.

[0055] In an embodiment, referring to Figure 3 and Figure 4, the first channel 2 and the second channel 3 are located below the first conveyor line 1, the first channel 2 is located in front of the second channel 3, the extension direction of the first channel 2 is parallel to the conveying direction of the first conveyor line 1, and the extension direction of the second channel 3 is perpendicular to the conveying direction of the first conveyor line 1;

[0056] The branch baffle 4 has a first surface 401 and a second surface 402 that are arranged opposite to each other, and the branch baffle 4 has a first side edge 403 and a second side edge 404 that are arranged opposite to each other; when the branch baffle 4 is rotated to the first working position, the first surface 401 is set upward, the second surface 402 is facing the head end of the second channel 3, the first side edge 403 is docked with the bottom of the rear end of the first conveyor line 1, and the second side edge 404 is blocked between the first channel 2 and the second channel 3; when the branch baffle 4 is rotated to the second working position, the first surface 401 is facing the front end of the first channel 2, the second surface 402 is facing the rear end of the first conveyor line 1 and the head end of the second channel 3, the first side edge 403 is blocked between the first conveyor line 1 and the first channel 2, and the second side edge 404 is blocked between the first channel 2 and the second channel 3.

[0057] This embodiment defines the relative position arrangement between the branch baffle 4 and the first conveyor line 1 , the first channel 2 , and the second channel 3 . Specifically, the rotation axis of the branch baffle 4 is horizontally arranged and located in the middle of the branch baffle 4 .

[0058] like Figure 3 As shown, when the branch baffle 4 rotates to the first working position, the branch baffle 4 is in an inclined state with the left side higher and the right side lower, the first surface 401 of the branch baffle 4 is set upward, and the second surface 402 of the branch baffle 4 faces the head end of the second channel 3 below, the first side edge 403 of the branch baffle 4 is docked with the bottom of the rear end of the first conveyor line 1, and the second side edge 404 of the branch baffle 4 is docked with the bottom of the system and blocked between the first channel 2 and the second channel 3; at this time, the parts to be processed conveyed to the rear end of the first conveyor line 1 can slide along the first surface 401 of the branch baffle 4 to the front end of the first channel 2 under the driving force of the first conveyor line 1 and the action of gravity, and then enter the black oxidation equipment 5 through the first channel 2 for black oxidation treatment.

[0059] like Figure 4As shown, when the shunt baffle 4 is rotated to the second working position, the shunt baffle 4 is in an inclined state with the left side low and the right side high, the first surface 401 of the shunt baffle 4 faces the front end of the first channel 2, the second surface 402 of the shunt baffle 4 faces the rear end of the first conveying line 1 and the head end of the second channel 3, the first side edge 403 of the shunt baffle 4 blocks between the first conveying line 1 and the first channel 2, and the second side edge 404 of the shunt baffle 4 is in abutment with the bottom of the system and blocks between the first channel 2 and the second channel 3; at this time, the parts to be processed conveyed to the rear end of the first conveying line 1 can fall along a parabolic direction to the second surface 402 of the shunt baffle 4 under the driving force of the first conveying line 1 and the action of gravity, and the parts to be processed will be bounced downward by the second surface 402 of the shunt baffle 4 to the head end of the second channel 3 after colliding with the second surface 402 of the shunt baffle 4, and then enter the electroplating equipment 6 through the second channel 3 for electroplating treatment.

[0060] In the electroplating process, impurities such as oil stains, dust, and oxide scale on the surface of the parts to be processed can seriously hinder the deposition of metal ions in the plating solution on the surface of the parts to be processed, resulting in poor adhesion of the plating layer, and even unable to form a uniform plating layer; therefore, the electroplating treatment has higher requirements for the surface cleanliness of the parts to be processed than the black oxidation treatment. Based on this demand, the first conveying line 1 and the first channel 2 and the second channel 3 are arranged in the form of a height difference in the embodiment, and through cooperation with the shunt baffle 4, the parts to be processed that need to be treated by black oxidation and have lower requirements for surface cleanliness can smoothly slide along the shunt baffle 4 to the first channel 2, so as to minimize the damage caused by the parts to be processed during conveying; and the parts to be processed that need to be treated by electroplating and have higher requirements for surface cleanliness are caused to fall along a parabolic line to the shunt baffle 4, and the shunt baffle 4 is used to receive and bounce the parts to be processed, and finally the parts to be processed fall to the head end of the second channel 3, so that multiple collisions and bouncing actions can promote the impurities remaining on the surface of the parts to be processed to fall off, and the parts to be processed can finally maintain a higher surface cleanliness for electroplating treatment.

[0061] Preferably, at the position where the parts to be processed for electroplating treatment collide, a layer of adsorbing material can be correspondingly arranged to adsorb the impurities such as debris and dust falling from the parts to be processed, so as to avoid the impurities from reattaching to the surface of the parts to be processed.

[0062] In an embodiment, referring to Figure 3 and Figure 4 , the transfer conveying system for part surface treatment further comprises a second conveying line 7, the second conveying line 7 is located below the first conveying line 1, the conveying direction of the second conveying line 7 is parallel to the conveying direction of the first conveying line 1, and the rear end of the second conveying line 7 is connected with the head end of the second channel 3; the second conveying line 7 is used to convey the parts to be processed from the front end to the rear end.

[0063] The second conveying line 7 is arranged below the first conveying line 1, so that the space below the first conveying line 1 can be fully utilized, and the conveying path of the parts to be treated is increased. While the first conveying line 1 is conveying a batch of parts to be treated to the black oxidation device 5 or the electroplating device 6, the second conveying line 7 can simultaneously convey another batch of parts to be treated to the second passage 3 for electroplating treatment, and the two conveying paths do not interfere with each other, so that the production efficiency of the parts can be further improved.

[0064] In an embodiment, referring to Figures 2 to 4 , the transfer conveying system for surface treatment of parts further comprises a machine cover 8, and the first conveying line 1, the first passage 2, the second passage 3, and the shunt baffle 4 are arranged inside the machine cover 8.

[0065] The machine cover 8 is provided with an observation port 801. When the shunt baffle 4 is rotated to the first working position, the observation port 801 faces the first surface 401. When the shunt baffle 4 is rotated to the second working position, the observation port 801 faces the head end of the second passage 3.

[0066] By arranging the machine cover 8, the first conveying line 1, the first passage 2, the second passage 3, and the shunt baffle 4 can be protected from external impurities, so that the normal operation of the corresponding components is not disturbed, and the running stability of the transfer conveying system is improved.

[0067] In the case of arranging the machine cover 8, as shown in Figure 3 , when the shunt baffle 4 is rotated to the first working position, the second side edge 404 of the shunt baffle 4 can be in abutment with the bottom wall of the machine cover 8. As shown in Figure 4 , when the shunt baffle 4 is rotated to the second working position, the first side edge 403 of the shunt baffle 4 can be in abutment with the top wall of the machine cover 8, and the second side edge 404 of the shunt baffle 4 can be in abutment with the bottom wall of the machine cover 8.

[0068] The machine cover 8 is provided with an observation port 801, through which an operator can observe the conditions inside the machine cover 8. Since the observation port 801 faces the first surface 401 when the shunt baffle 4 is rotated to the first working position, and faces the head end of the second passage 3 when the shunt baffle 4 is rotated to the second working position, the operator can observe the conveying conditions of the parts to be treated through the observation port 801 when the shunt baffle 4 is in different working positions. In addition, a small number of parts to be treated that are missed or temporarily added can be supplemented through the observation port 801 to the first passage 2 or the second passage 3, without the need for transmission through the first conveying line 1 or the second conveying line 7, so that the flexibility of use is higher.

[0069] Preferably, as shown in Figure 2As shown, a cover 802 is rotatably connected to the hood 8, and the cover 802 is used to cover the observation port 801; in this way, the cover 802 can be opened when observation or feeding is required, and the cover 802 can be closed after use to prevent external impurities from invading the interior of the hood 8 through the observation port 801.

[0070] In one embodiment, reference Figure 5 and Figure 6 When the branch baffle 4 rotates to the third working position, the first surface 401 is set upward, the second surface 402 faces the head end of the second channel 3, the first side 403 is located below the bottom of the first conveyor line 1, and the second side 404 is located above the bottom of the first channel 2. A leakage channel 9 is formed between the second side 404 and the bottom of the first channel 2, and the leakage channel 9 connects the front end of the first channel 2 and the head end of the second channel 3.

[0071] like Figure 5 As shown, when the branch baffle 4 is rotated to the third working position, the branch baffle 4 is in an inclined state with the left side higher and the right side lower, the first surface 401 of the branch baffle 4 is set upward, the second surface 402 of the branch baffle 4 is facing the head end of the second channel 3 below, the first side edge 403 of the branch baffle 4 is located below the bottom of the first conveyor line 1, and the second side edge 404 of the branch baffle 4 is located above the bottom of the first channel 2 (i.e., the bottom wall of the hood 8); Figure 6 As shown, at this time, the gap in the vertical direction between the second side 404 and the bottom of the first channel 2 (i.e., the bottom wall of the hood 8) constitutes a leakage channel 9, and the parts to be processed in the second channel 3 can be diverted to the first channel 2 through the leakage channel 9.

[0072] Based on the above arrangement, in actual application, when the second channel 3 is overloaded with parts to be processed that have not been electroplated in time, in order to avoid subsequent serious blockage problems, if the batch of parts is not strictly required to be electroplated, the operator can temporarily rotate the branch baffle 4 to the third working position to connect the second channel 3 with the first channel 2, so that the backlog of parts to be processed stacked in the second channel 3 can be diverted to the first channel 2 for black oxidation treatment under the action of external force, and then the branch baffle 4 can be reset to the second working state; in this way, the blockage of parts in the second channel 3 can be alleviated.

[0073] It is understandable that when the branch baffle 4 rotates to the third working position, the branch baffle 4 can be limited by the snap structure to prevent the branch baffle 4 from continuing to rotate and keep it at the current angular position.

[0074] Preferably, the bottom of the leakage passage 9 can be provided with an inclined structure, which is higher near the side of the second passage 3 and lower near the side of the first passage 2, so that when the shunt baffle 4 is turned to the third working position, the stacked parts to be processed in the second passage 3 are more likely to slide to the first passage 2 under the action of gravity, thereby better achieving the shunting of the stacked parts.

[0075] In an embodiment, referring to Figures 3 to 6 , the bottom of the leakage passage 9 is provided with a surrounding structure 10; when the shunt baffle 4 is turned to the third working position, the surrounding structure 10 is used to block the parts to be processed in the second passage 3 from entering the first passage 2; when the shunt baffle 4 is turned to the first working position, the top of the surrounding structure 10 is in abutment with the second side edge 404.

[0076] Specifically, the surrounding structure 10 can be protruded on the bottom wall of the cover 8. As shown in Figure 3 and Figure 4 , the height of the second side edge 404 of the shunt baffle 4 in the first working position is generally higher than that in the second working position; to adapt to this structural feature, the embodiment is correspondingly provided with the surrounding structure 10, so that when the shunt baffle 4 is turned to the first working position, the second side edge 404 of the shunt baffle 4 is in abutment with the top of the surrounding structure 10; when the shunt baffle 4 is turned to the second working position, the second side edge 404 of the shunt baffle 4 is in abutment with the bottom of the system (i.e. the bottom wall of the cover 8). In this way, the surrounding structure 10 can better adapt to the height difference of the second side edge 404 in different working positions, avoiding the problem of excessive gap between the second side edge 404 and the bottom of the system (i.e. the bottom wall of the cover 8) in the first working position, or the problem of interference between the second side edge 404 and the bottom of the system (i.e. the bottom wall of the cover 8) in the second working position, due to improper size and position of the shunt baffle 4.

[0077] In addition, when the shunt baffle 4 is turned to the third working position, as shown in Figure 5 and Figure 6 , the parts to be processed in the second passage 3 that are higher than the surrounding structure 10 can bypass the surrounding structure 10 and be shunted to the first passage 2, while the remaining parts to be processed in the second passage 3 are blocked by the surrounding structure 10 and cannot enter the first passage 2; that is, the surrounding structure 10 can be used to control the number of parts to be processed shunted from the second passage 3 to the first passage 2 at this time, only to alleviate the congestion of the second passage 3, which can avoid too many parts to be processed being shunted to the first passage 2.

[0078] In an embodiment, referring to Figure 3 and Figure 4The transfer system for part surface treatment further comprises a spraying device 11 arranged at the bottom of the rear end of the first conveying line 1, and the spraying direction of the spraying device 11 is horizontally rearward.

[0079] When the shunt baffle 4 is rotated to the first working position, the spraying device 11 sprays upward toward the first surface 401; when the shunt baffle 4 is rotated to the second working position, the spraying device 11 sprays toward the second surface 402.

[0080] In the embodiment, as shown in Figure 3 When the shunt baffle 4 is rotated to the first working position, the spraying device 11 can, on the one hand, utilize the pressure generated during spraying to push the parts to be treated at the junction between the first conveying line 1 and the shunt baffle 4, so as to ensure that the parts to be treated can smoothly slide down the shunt baffle 4 to the first channel 2, avoiding blockage at the junction between the first conveying line 1 and the shunt baffle 4 due to too many parts to be treated; on the other hand, the spraying operation of the spraying device 11 can be used to remove impurities such as oil stains, dust, debris, and oxide scales remaining on the surface of the parts to be treated, so as to improve the subsequent surface treatment quality of the parts to be treated.

[0081] As shown in Figure 4 When the shunt baffle 4 is rotated to the second working position, the spraying device 11 can, on the one hand, utilize the pressure generated during spraying to horizontally push the parts to be treated dropped from the rear end of the first conveying line 1, so as to ensure that the parts to be treated can drop along a parabolic direction to the second surface 402 of the shunt baffle 4 under the horizontal action force, and drop to the head end of the second channel 3 under the rebounding action of the second surface 402, avoiding the parts to be treated from directly dropping to the head end of the second channel 3 due to insufficient horizontal driving force of the first conveying line 1, so as to cause the impurities on the surface of the parts to be treated to be unable to be completely removed, and avoiding the parts to be treated from being damaged due to too high dropping height and the shunt baffle 4 not forming a buffering action in the middle; on the other hand, the spraying operation of the spraying device 11 can be used to further remove impurities such as oil stains, dust, debris, and oxide scales remaining on the surface of the parts to be treated, so as to improve the subsequent surface treatment quality of the parts to be treated.

[0082] In an embodiment, referring to Figure 4 The second surface 402 is provided with an elastic material layer 405.

[0083] By arranging the elastic material layer 405 on the second surface 402, the parts to be treated can be bounced out by elastic action when falling along the parabolic direction to the second surface 402, so that the parts to be treated can accurately fall to a position closer to the first end of the second channel 3, thereby enabling the impurities remaining on the surface of the parts to be treated to be removed through multiple collisions and rebounding actions. In addition, the elastic material layer 405 can also absorb a part of the impact energy when the parts to be treated fall, thereby forming a certain buffering effect on the parts to be treated, so as to avoid damage to the parts to be treated to the greatest extent during the process of multiple collisions and rebounds.

[0084] In an embodiment, referring to Figure 4 , the bottom of the first end of the second channel 3 is provided with a buffer material layer 12.

[0085] Specifically, the buffer material layer 12 can be arranged on the bottom wall of the machine cover 8. By arranging the buffer material layer 12, the parts to be treated falling downward after the rebounding action of the shunt baffle 4 can be buffered, so as to further reduce the damage caused by the collision process to the parts to be treated.

[0086] In an embodiment, referring to Figure 3 , the shunt baffle 4 is provided with a material discharge through hole (not shown in the figure); the part surface treatment transfer conveying system further comprises a turnover vane plate (not shown in the figure), which is rotatably connected in the material discharge through hole;

[0087] When the shunt baffle 4 is rotated to the first working position, the turnover vane plate is used to rotate relative to the shunt baffle 4 to drive the parts to be treated on the shunt baffle 4 to fall through the material discharge through hole to the first end of the second channel 3.

[0088] In actual application process, when the shunt baffle 4 is in the first working position, if too many parts to be treated which cannot be treated by black oxidation in time are accumulated on the shunt baffle 4, in order to avoid serious jamming problem in the subsequent process, under the condition that the parts in this batch are not strictly limited to be treated by black oxidation, the operator can rotate the turnover vane plate to drive part of the parts to be treated on the first surface 401 to fall downward through the material discharge through hole to the first end of the second channel 3, and the subsequent parts to be treated can be treated by electroplating. In this way, the shunting operation of part of the parts to be treated is realized, which can effectively alleviate the part jamming condition when the shunt baffle 4 is in the first working position.

[0089] In actual operation, the turning of the turning vane can be driven by manual operation or automatic control. For example, the turning vane can be driven to turn by a driving device such as a motor; and the turning of the turning vane can be automatically controlled when the sensor detects the part blocking condition on the shunt baffle 4 through signal transmission control between the sensor, the controller and the driving device. This automatic driving mode not only can improve the response speed, but also can reduce human operation errors, and can further improve the automation and intelligence of the transfer conveying system.

[0090] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like made by using the content of the present application specification and drawings within the technical concept of the present application is included in the patent protection scope of the present application.
