Description

Technical Field

[0001] This invention relates to the technical field of work transportation, and particularly to transfer modules, workpiece cleaning devices, and coating production lines. Background Technology

[0002] Electrode plates are used in the coating process, and cleaning is a key step to ensure the cleanliness of the electrode plate surface and prevent impurities from affecting the quality of subsequent coating processes.

[0003] On the production line, electrode plates that need to be cleaned are generally placed horizontally on the conveyor belt (to ensure that the electrode plates can be picked up horizontally in subsequent processes). In order to ensure complete cleaning, the electrode plates need to be placed vertically. Currently, the horizontally placed electrode plates are mainly picked up by the suction or clamping of the robotic arm. Then, the electrode plates are placed vertically in the cleaning device through a complex transformation of the robotic arm. After the electrode plates are cleaned, they are taken out by the robotic arm and placed horizontally on the conveyor belt. This transfer method of transferring the electrode plates from horizontal to vertical by the suction or clamping of the robotic arm has an additional rotation transformation, which makes the structure of the entire transfer module more complex. The multi-step transformation leads to low efficiency. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a transfer module that more conveniently transfers workpieces from a horizontal to a vertical position, thereby improving transfer efficiency.

[0005] The present invention also proposes a workpiece cleaning device having the above-mentioned transfer module.

[0006] The present invention also proposes a production line having the above-mentioned workpiece cleaning device.

[0007] According to an embodiment of the present invention, a transfer module includes a frame, a first conveying mechanism, and a dual-axis moving mechanism. The frame is capable of horizontally placing a workpiece, and the front end of the workpiece is provided with a hook groove and a hanging hole. The hook groove has an open guide section and a hook section. The first conveying mechanism is disposed on the frame and is used to convey the workpiece in the front-back direction. A plurality of hangers are disposed on the first conveying mechanism and are distributed along the operating path of the first conveying mechanism, with a gap between adjacent hangers. The dual-axis moving mechanism is mounted on the frame, and the execution end of the dual-axis moving mechanism is equipped with a first hook. The dual-axis moving mechanism can drive the first hook to slide in the left-right direction and the up-down direction. Under the drive of the dual-axis moving mechanism, the first hook can enter the hook section from the open guide section and hook up the horizontally placed workpiece to the hanger. The hanger can hook the hanging hole to suspend the workpiece in the gap.

[0008] It has at least the following beneficial effects: A dual-axis moving mechanism drives the first hook to slide in the left-right and up-down directions, allowing it to enter the hooking section from the opening guide section of the workpiece hooking slot. This hooks up the horizontally placed workpiece, and the dual-axis moving mechanism then transfers the workpiece to the hanger of the first conveying mechanism via the first hook. The hanger hooks the workpiece through its hanging hole, suspending it between adjacent hangers. This achieves the transfer of the workpiece from a horizontal to a vertical position, eliminating the need for the complex rotational transformation of the robotic arm in existing technologies. This simplifies the structure of the transfer module. Furthermore, the continuous conveying of the first conveying mechanism provides space for subsequent workpiece transfers, ensuring continuous transfer efficiency and providing a guarantee for subsequent workpiece cleaning.

[0009] According to some embodiments of the present invention, the first hook has a hook handle and a hook support. The side of the hook support used to receive the workpiece is provided with an arc-shaped receiving groove. The arc-shaped receiving groove is connected to the hook handle through an inclined plane. The angle between the tangent of the arc-shaped receiving groove at the free end of the hook support and the horizontal plane is α, and the angle between the inclined plane and the horizontal plane is β, where α > β.

[0010] According to some embodiments of the present invention, the dual-axis moving mechanism includes a slide plate and a mounting plate. The slide plate is slidably disposed on the frame in the left-right direction, and the mounting plate is slidably disposed on the slide plate in the up-down direction. A first hook is connected to the slide plate.

[0011] According to some embodiments of the present invention, the workpiece is provided with a plurality of hook grooves and hanging holes arranged in the left-right direction, the first hook is provided in a one-to-one correspondence with the hook groove, and the hanger is provided with a second hook, the second hook being provided in a one-to-one correspondence with the hanging hole.

[0012] According to some embodiments of the present invention, the first conveying mechanism includes two chains, which are spaced apart in the left-right direction. The two chains can operate synchronously and their links are arranged opposite each other in the left-right direction. A bracket is connected between the two opposite links.

[0013] According to some embodiments of the present invention, a second conveying mechanism is further included. The second conveying mechanism is disposed on the frame and is used to convey the workpiece in the front-back direction. The workpiece is placed horizontally on the second conveying mechanism. The second conveying mechanism and the first conveying mechanism are arranged side by side in the left-right direction. The second conveying mechanism is provided with a clearance opening for avoiding the first hook.

[0014] According to a second aspect of the present invention, a workpiece cleaning apparatus includes a transfer module and a cleaning assembly according to the first aspect of the present invention. The cleaning assembly is disposed on a frame, and a plurality of cleaning assemblies are disposed thereon. The plurality of cleaning assemblies are arranged in a front-back direction above a first conveying mechanism, and the cleaning assemblies are used to clean workpieces. Two transfer modules are disposed thereon. The front transfer module is used to transfer horizontally placed workpieces to the first conveying mechanism, and the rear transfer module is used to transfer workpieces on the first conveying mechanism to the frame and place them horizontally.

[0015] It has at least the following beneficial effects: The two transfer modules work in conjunction with the second and first conveying mechanisms, allowing the second conveying mechanism to maintain its conveying function while the first conveying mechanism carries the workpiece for cleaning. After cleaning, the workpiece is transferred by the rear transfer module to the second conveying mechanism for horizontal placement, facilitating retrieval in subsequent processes. The second conveying mechanism does not need to stop and wait while conveying workpieces; instead, it moves with the first conveying mechanism, ensuring the continuity of the production line and improving efficiency.

[0016] According to some embodiments of the present invention, the cleaning assembly includes a liquid spraying tank and an air jetting component. The liquid spraying tank is disposed on the frame, and the bottom of the liquid spraying tank is provided with a plurality of rows of liquid spraying holes, which are arranged in a front-to-back direction, with each row having a plurality of liquid spraying holes. The liquid spraying holes are arranged in a left-to-right direction, and the liquid spraying tank can spray cleaning liquid onto the workpiece below through the liquid spraying holes to clean the workpiece. The air jetting component is disposed on the frame and is located behind the liquid spraying tank. The air jetting component is used to spray air downwards to dry the suspended workpiece.

[0017] According to some embodiments of the present invention, the jetting component includes a gas-gathering buffer tank and a high-pressure air pump. Several gas-gathering buffer tanks are provided, and the gas-gathering buffer tanks are connected to the high-pressure air pumps. The high-pressure air pumps are used to supply high-pressure gas to the gas-gathering buffer tanks. Several rows of jet holes are provided at the bottom of the gas-gathering buffer tanks, each row having several jet holes. The several jet holes are arranged in a left-right direction and are used to jet gas onto the workpiece below to blow away the cleaning liquid on the workpiece.

Detailed Implementation

[0023] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0024] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0025] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0026] Reference Figures 1 to 12This invention discloses a transfer module, including a frame 100, a first conveying mechanism 200, and a dual-axis moving mechanism 300. The frame 100 can horizontally place a workpiece 400. The front end of the workpiece 400 is provided with a hook groove 410 and a hanging hole 420. The hook groove 410 has an open guide section 411 and a hook section 412. The first conveying mechanism 200 is disposed on the frame 100 and is used to convey the workpiece 400 in the front-back direction. The first conveying mechanism 200 is provided with a plurality of hangers 220, which are distributed along the operating path of the first conveying mechanism 200, and there is a gap 230 between adjacent hangers 220. The dual-axis moving mechanism 300 is mounted on the frame 100. The execution end of the dual-axis moving mechanism 300 is equipped with a first hook 330. The dual-axis moving mechanism 300 can drive the first hook 330 to slide in the left-right direction and the up-down direction. Under the drive of the dual-axis moving mechanism 300, the first hook 330 can slide from the open guide section 411 to the hook section 412. The section 411 enters the hook section 412 and hooks the horizontally placed workpiece 400 to the hanger 220. The hanger 220 can hook the workpiece 400 through the hook hole 420, allowing the workpiece 400 to hang in the interval 230. The open guide section 411 is used to guide and correct the first hook 330, reducing the positioning accuracy requirements of the hooking action. The hook section 412 is a limit groove of equal width, used to form a stable hook with the first hook 330, preventing the workpiece 400 from falling off during lifting and transfer. Both the hook section 412 and the hook support 332 of the first hook 330 are equipped with anti-detachment stops to prevent the workpiece 400 from easily detaching from the first hook 330 under the action of external force when the first hook 330 hooks the workpiece 400. The width of the interval 230 is greater than the thickness of the workpiece 400, so that the workpiece 400 will not collide or rub against adjacent workpieces 400 in the vertically suspended state, while ensuring that the cleaning fluid and airflow can pass smoothly, improving the subsequent cleaning and drying effect.

[0027] Understandably, the transfer module as a whole realizes the transfer of workpiece 400 from horizontal placement to vertical suspension. The frame 100 is the foundation for the whole machine and is formed by splicing profiles or bending sheet metal. The second conveying mechanism 500 and the first conveying mechanism 200 are both installed on the frame 100. The second conveying mechanism 500 is a conveyor belt, which includes two parallel conveyor belts distributed in the left and right directions. There is a clearance opening 510 between the two conveyor belts. The workpiece 400 is placed between the two conveyor belts, that is, the left and right ends of the workpiece 400 are placed on the two conveyor belts. The set open guide section 411 and hook section 412 form an L-shaped hook groove 410, and the hook section 412 of the L-shaped hook groove 410 extends in the same direction. When the first hook 330 descends, it can pass through the open guide section 411 and reach the lower end of the workpiece 400. When the first hook 330 moves horizontally, its hook support 332 hooks the bottom edge of the hook section 412, and then it is lifted to complete the hooking action. This process does not require additional positioning of the workpiece 400. It can achieve hooking and transfer of the workpiece 400 by relying solely on the geometric guidance of the hook groove 410 and the dual-axis cooperative trajectory of the first hook 330.

[0028] It should be noted that the dual-axis moving mechanism 300 drives the first hook 330 to slide in the left-right and up-down directions, allowing the first hook 330 to enter the hooking section 412 from the opening guide section 411 of the hooking groove 410 of the workpiece 400, thereby hooking up the horizontally placed workpiece 400. The dual-axis moving mechanism 300 then transfers the workpiece 400 to the hanger 220 of the first conveying mechanism 200 through the first hook 330. The hanger 220 hooks the workpiece 400 through the hanging hole 420, so that the workpiece 400 is suspended in the interval 230 between adjacent hangers 220, realizing the transfer of the workpiece 400 from a horizontal to a vertical position. This eliminates the need for the complex rotation transformation of the robotic arm in the prior art, simplifying the structure of the transfer module. At the same time, the continuous conveying of the first conveying mechanism 200 provides space for subsequent workpiece transfer, ensuring the continuous transfer of the workpiece 400, improving the transfer efficiency of the workpiece 400, and providing a guarantee for the subsequent cleaning of the workpiece 400.

[0029] The transfer module can complete the entire process of hooking, lifting, transferring, and mounting workpiece 400 through only two-dimensional linear motion, simplifying the mechanical structure, control system, and motion logic of the transfer module, and reducing equipment costs and failure rates. At the same time, through the continuous operation of the first conveying mechanism 200, a transfer space is continuously provided for the dual-axis moving mechanism 300, ensuring that the transfer action of workpiece 400 is continuous, without waiting or stopping, which significantly improves the transfer efficiency of workpiece 400. Moreover, the workpiece 400 is vertically suspended without obstruction or contact surface, which provides a guarantee for subsequent full-surface cleaning and drying of workpiece 400.

[0030] Reference Figures 8 to 12The first hook 330 has a hook handle 331 and a hook support 332. The hook support 332 is provided with an arc-shaped receiving groove 332a on one side for receiving the workpiece 400. The arc-shaped receiving groove 332a is connected to the hook handle 331 through an inclined surface 332b. The angle between the tangent surface of the arc-shaped receiving groove 332a at the intersection with the free end of the hook support 332 and the horizontal plane is α, and the angle between the inclined surface 332b and the horizontal plane is β, where α > β. It should be noted that the inclination of the inclined plane 332b is more gradual. During the movement of the first hook 330, when the workpiece 400 contacts the second conveying mechanism 500, it can swing backward. This allows the workpiece to be placed horizontally by the second conveying mechanism 500. The gentle inclination of the inclined plane 332b reduces the resistance to the swinging of the workpiece 400. Meanwhile, the relatively steep position of the arc-shaped receiving groove 332a makes it easier for the workpiece 400 to detach from the first hook 330 during the swinging process. The length of the inclined plane 332b is greater than the side of the arc-shaped receiving groove 332a near the free end of the hook support 332. Because the arc-shaped receiving groove 332a is shorter, the workpiece 400 can detach from the first hook 330 more easily, and as the first hook 330 moves in the left and right directions, the efficiency of the workpiece 400 detaching from the first hook 330 is increased. It should be noted that the first hook 330 is a one-piece molded metal structural component, with a hook handle 331 and a hook support 332. The hook handle 331 is used to rigidly connect with the execution end of the dual-axis moving mechanism 300. The connection method can be threaded fastening, pin locking or flange connection to ensure connection strength and motion synchronization.

[0031] In some embodiments, the dual-axis moving mechanism 300 includes a slide plate 310 and a mounting plate 320. The slide plate 310 is slidably disposed on the frame 100 in the left-right direction, and the mounting plate 320 is slidably disposed on the slide plate 310 in the up-down direction. A first hook 330 is connected to the slide plate 310. It is understood that the slide plate 310 and the mounting plate 320 are movable components of the dual-axis moving mechanism 300. Both the slide plate 310 and the mounting plate 320 are driven by a power component, which can be a pneumatic cylinder or an electric cylinder. An electric cylinder is a device that uses a motor to drive a lead screw and nut mechanism to achieve linear movement. The slide plate 310 and the mounting plate 320 are connected to the nut of the lead screw and nut mechanism, and the electric cylinder can control the linear sliding of the slide plate 310 and the mounting plate 320.

[0032] Reference Figure 1 , Figure 8 and Figure 9The workpiece 400 is provided with several hook grooves 410 and hanging holes 420 arranged in a left-right direction. A first hook 330 is correspondingly set with each hook groove 410, and a second hook 221 is provided on the hanger 220, with each second hook 221 corresponding with each hanging hole 420. It can be understood that the hook grooves 410 and hanging holes 420 correspond to different hooks, so that when the first hook 330 hooks the workpiece 400, it can simultaneously place the workpiece 400 onto the second hook 221. The multiple hook grooves 410 and hanging holes 420 can distribute the weight of the workpiece 400, ensuring the balance of the workpiece 400 when it is hung.

[0033] In some embodiments, the first conveying mechanism 200 includes two chains 210, spaced 230 apart in the left-right direction. The two chains 210 operate synchronously, with each link facing the other in the left-right direction. A bracket 220 is connected between the two opposing links. This installation method ensures that the bracket 220 remains horizontally stable during conveying, thereby ensuring the stability of the workpiece 400 during transport and facilitating subsequent cleaning. The chains 210 are driven by a servo motor, and precise speed adjustment and anti-deviation are achieved in conjunction with a tension wheel and guide wheel. It is understood that the two chains 210 are driven by the same drive shaft and synchronous sprocket, enabling synchronous and unidirectional operation, with each link of the two chains 210 facing the other in the left-right direction. The two ends of the bracket 220 are respectively connected between the two opposing links using pins, bolts, or clips for fastening, ensuring that the bracket 220 does not loosen or deform during operation.

[0034] In some embodiments, a second conveying mechanism 500 is further included. The second conveying mechanism 500 is disposed on the frame 100 and is used to convey the workpiece 400 in the front-to-back direction. The workpiece 400 is placed horizontally on the second conveying mechanism 500. The second conveying mechanism 500 and the first conveying mechanism 200 are arranged side by side in the left-to-right direction. The second conveying mechanism 500 is provided with a clearance opening 510 for avoiding the first hook 330. The size of the clearance opening 510 is precisely matched with the movement trajectory of the first hook 330, ensuring that the slide plate 310 drives the first hook 330 to move vertically without interference. In addition, the edge of the clearance opening 510 is provided with a flexible buffer pad, which reduces the risk of mechanical collision and avoids the accumulation of metal shavings that may affect the running accuracy of the hook. The second conveying mechanism 500 adopts a variable frequency speed control belt structure.

[0035] A workpiece cleaning device includes a transfer module and a cleaning assembly 600. The cleaning assembly 600 is mounted on a frame 100, and several cleaning assemblies 600 are arranged in a front-to-back direction above a first conveying mechanism 200. The cleaning assembly 600 is used to clean workpieces 400. Two transfer modules are provided: a forward transfer module transfers horizontally placed workpieces to the first conveying mechanism 200, and a rearward transfer module transfers workpieces from the first conveying mechanism 200 to the frame 100 for horizontal placement. The two transfer modules, in conjunction with a second conveying mechanism 500 and the first conveying mechanism 200, allow the second conveying mechanism 500 to maintain conveying while the first conveying mechanism 200 carries the workpieces 400 for cleaning. After cleaning, the workpieces are transferred by the rearward transfer module to the second conveying mechanism 500 for horizontal placement, facilitating retrieval in subsequent processes. The second conveying mechanism 500 does not need to stop while conveying workpieces 400; instead, it moves with the first conveying mechanism 200, ensuring production line continuity and improving efficiency.

[0036] In some embodiments, the cleaning assembly 600 includes a spray tank 610 and an air jet 620. The spray tank 610 is disposed on the frame 100, and its bottom has several rows of spray holes 611 arranged in a front-to-back direction, with each row having several spray holes 611. The spray holes 611 are also arranged in a left-to-right direction. The spray tank 610 can spray cleaning fluid onto the workpiece 400 below through the spray holes 611 to clean the workpiece 400. The air jet 620 is disposed on the frame 100, behind the spray tank 610, and is used to spray air downwards to dry the suspended workpiece 400. It should be noted that a water receiving tank 700 is provided below both the spray tank 610 and the air jet 620. The water receiving tank 700 is mainly used to collect water discharged from the spray tank 610 and the air jet 620 during the processing of the workpiece 400, preventing wastewater from being discharged indiscriminately. Understandably, the spray tank 610 is a closed or semi-closed liquid storage tank, with several spray holes 611 forming a fully covered spray area. The spray tank 610 can evenly spray cleaning fluid onto the suspended workpiece 400 through the spray holes 611, achieving cleaning of the entire surface of the workpiece 400 without dead angles. The cleaning fluid can be clean water, cleaning agent, or purified water.

[0037] In some embodiments, the jetting component 620 includes a gas-gathering buffer tank 621 and a high-pressure air pump 622. The gas-gathering buffer tank 621 is provided with several units and is connected to the high-pressure air pump 622. The high-pressure air pump 622 supplies high-pressure gas to the gas-gathering buffer tank 621. The bottom of the gas-gathering buffer tank 621 is provided with several rows of jet holes 621a, each row having several jet holes 621a arranged in a left-right direction. The jet holes 621a are used to jet gas onto the workpiece 400 below to blow away the cleaning fluid on the workpiece 400. It is understood that the high-pressure air pump 622 is a conventional device with adjustable output pressure to ensure process adaptability for different workpiece surface cleanliness and dryness levels. The gas-gathering buffer tank 621 is also equipped with a pressure sensor and a pressure relief valve to monitor and stabilize the air supply pressure in real time, preventing sudden airflow changes from affecting the drying effect. The axes of all jet holes 621a are vertically downward.
