Description

In related technologies, a layer of primer is usually pre-applied on the bipolar plates, and then the bipolar plates and sealing rings are bonded together through the primer.

[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0046] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to express a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0047] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0048] Furthermore, the terms "first," "second," and the like are primarily used to distinguish between different devices, elements, or components, which may or may not have the same specific type and configuration, and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0049] As mentioned in the background technology, in the related art, a layer of primer is usually pre-applied on the bipolar plate, and then the bipolar plate and the sealing ring are bonded together through the primer. However, due to the thin thickness of the bipolar plate, it is easy to warp, resulting in uneven glue application, which makes the sealing ring unable to be firmly bonded to the bipolar plate.

[0050] In order to solve the above problems, the embodiments of the present application provide a positioning device and a dispensing device. The positioning device can provide uniform supporting force on the supporting surface within the entire non-dispensing surface when the part to be dispensed is placed on the supporting surface, thereby avoiding warping caused by uneven local force on the part to be dispensed, and minimizing problems such as inaccurate dispensing position and uneven thickness of the glue layer, thereby ensuring the quality of dispensing and ensuring that the sealing ring can be firmly bonded to the bipolar plate.

[0051] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0052] See also Figures 1 to 3 This embodiment provides a positioning device 1, which is used for dispensing equipment. The positioning device 1 includes: a positioning base 100 and a positioning structure 200. The positioning base 100 includes a bearing surface 110, and the bearing surface 110 is used to support a part to be dispensed 2. The part to be dispensed 2 includes a dispensing surface 20 and a non-dispensing surface; the positioning structure 200 is used to make the non-dispensing surface of the part to be dispensed 2 fit with the bearing surface 110 to prevent the part to be dispensed from warping.

[0053] Among them, the non-glue surface of the above-mentioned part to be glued 2 is fitted with the carrying surface 110. It should be understood that the non-glue surface is in contact with the entire surface of the carrying surface 110 as much as possible, without obvious gaps or voids, so as to ensure that the part to be glued 2 is not prone to warping or displacement during the gluing process. The non-glue surface of the part to be glued 2 is fitted with the carrying surface 110 by appropriate pressure or fixing. For example, the positioning structure 200 can apply a certain pressure so that the non-glue surface of the part to be glued 2 is tightly pressed against the carrying surface 110, thereby achieving comprehensive fitting.

[0054] In addition, this embodiment is described by taking the part 2 to be dispensed as a bipolar plate as an example.

[0055] When dispensing is required, the part to be dispensed 2 is placed on the bearing surface 110 of the positioning base 100, and the non-dispensing surface of the part to be dispensed 2 is made to fit with the bearing surface 110 through the positioning structure 200, ensuring that the position of the part to be dispensed 2 on the bearing surface 110 is accurately fixed. Moreover, when the part to be dispensed 2 is placed on the bearing surface 110, the bearing surface 110 can provide uniform supporting force within the entire non-dispensing surface, thereby avoiding warping caused by uneven force on the part to be dispensed 2. For example, if the part to be dispensed 2 is a thin bipolar plate, if there is no uniform support, It is easy for the bipolar plate to bend or warp under the influence of its own gravity or external factors, and the presence of the supporting surface 110 can effectively disperse the gravity of the bipolar plate and keep it flat. The positioning structure 200 further enhances the fixing effect on the bipolar plate by making the non-glue-dispensing surface of the bipolar plate fit with the supporting surface 110, which can prevent the bipolar plate from being displaced or deformed during the gluing process, thereby reducing the possibility of warping of the bipolar plate, avoiding problems such as inaccurate gluing position and uneven glue layer thickness as much as possible, thereby ensuring the gluing quality and ensuring that the sealing ring can be firmly bonded to the bipolar plate.

[0056] In a possible embodiment, the glue dispensing surface 20 of the part to be glued 2 includes a glue dispensing area 20a and a non-glue dispensing area 20b, and the non-glue dispensing area 20b is the edge area of ​​the glue dispensing surface 20; the positioning structure 200 includes a first positioning structure 210, and the first positioning structure 210 includes a positioning pressure block 211, and the positioning pressure block 211 is movably arranged in the horizontal direction relative to the positioning base 100, and the positioning pressure block 211 is movably arranged in the vertical direction relative to the positioning base 100.

[0057] The horizontal direction is parallel to the plane where the bearing surface 110 is located, and the vertical direction is Figure 1 The direction indicated by arrow Y.

[0058] When performing the dispensing operation, first make the positioning pressing block 211 in a state of avoiding the glue-dispensing part 2, so that the glue-dispensing part 2 can be smoothly placed on the carrying surface 110 of the positioning base 100. After the glue-dispensing part 2 is placed on the carrying surface 110, the positioning pressing block 211 moves relative to the positioning base 100 in the horizontal direction, and adjusts its position in the direction parallel to the carrying surface 110 so that the positioning pressing block 211 corresponds to the non-glue-dispensing area 20b of the glue-dispensing part 2 in the vertical direction. Then, the positioning pressing block 211 moves relative to the positioning base 100 in the vertical direction, that is, moves downward in a direction perpendicular to the carrying surface 110, close to the glue-dispensing part 2 located on the carrying surface 110, and the positioning pressing block 211 moves relative to the positioning base 100 in the vertical direction. The block 211 gradually approaches the glue dispensing surface 20 of the part to be glued 2, and finally contacts the non-glue dispensing area 20b and applies a certain pressure, so that the non-glue dispensing surface of the part to be glued 2 is tightly fitted with the bearing surface 110. At this time, the glue dispensing operation is performed on the glue dispensing area 20a of the glue dispensing surface 20. During the glue dispensing process, the positioning block 211 maintains pressure on the non-glue dispensing area 20b to ensure that the part to be glued 2 does not move or warp. After the glue dispensing is completed, the positioning block 211 first moves upward in the vertical direction, away from the part to be glued 2, and then adjusts the position of the positioning block 211 in the horizontal direction to return to the initial avoidance state, so as to remove the glued part 2 to be glued or perform the positioning operation of the next part 2 to be glued.

[0059] In this embodiment, the positioning block 211 can be adjusted in the horizontal and vertical directions to accurately match the positioning block 211 with the non-glue area 20b of the glue dot surface 20 of the part to be glued 2, and apply pressure to achieve precise positioning, thereby ensuring the position accuracy of the part to be glued 2 during the glue dot process and improving the glue dot accuracy. Moreover, since the positioning block 211 can be adjusted in the horizontal direction, it can adapt to parts to be glued 2 of different sizes and shapes. For parts to be glued 2 of different specifications, the position of the positioning block 211 can be flexibly adjusted according to the position of the non-glue area 20b of its glue dot surface 20, thereby improving the versatility of the positioning device 1. In addition, the positioning block 211 only contacts the non-glue area 20b of the glue dot surface 20 and will not affect the glue dot area 20a, thereby ensuring the integrity and cleanliness of the glue dot area 20a and avoiding problems such as glue point contamination, damage or uneven glue dot due to contact between the positioning structure 200 and the glue dot area 20a.

[0060] In one possible embodiment, see Figure 3 The positioning pressing blocks 211 include multiple positioning pressing blocks 211 that are spaced apart along the circumference of the bearing surface 110 .

[0061] By fixing the part to be glued 2 from different directions through multiple positioning blocks 211, uniform pressure can be provided in the circumferential direction, so that the non-glue surface of the part to be glued 2 and the bearing surface 110 can fit more closely, thereby improving the stability of the part to be glued 2 on the positioning base 100. In addition, multiple positioning blocks 211 apply pressure from different angles to limit the rotational movement of the part to be glued 2, ensuring that it always maintains the correct posture during the gluing process. The uniform pressure of multiple positioning blocks 211 can also ensure that the gluing surface 20 of the part to be glued 2 remains flat. During the gluing process, the flat gluing surface 20 is conducive to the uniform distribution and solidification of the glue, thereby improving the quality and consistency of gluing.

[0062] In a possible embodiment, the width of the positioning pressing block 211 matches the width of the non-dot area.

[0063] Among them, the width of the positioning block 211 matches the width of the non-glue area 20b. It should be understood that the width of the positioning block 211 is equal to or approximately equal to the width of the non-glue area. When the positioning block 211 contacts the non-glue area 20b, it can completely cover or basically cover the non-glue area 20b, and there is no obvious width difference. For example, if the width of the non-glue area 20b is 10 mm, then the width of the positioning block 211 can be 10 mm or within a reasonable error range, such as between 9.8 mm and 10.2 mm.

[0064] The width of the positioning block 211 matches the width of the non-glue-dispensing area 20b, which can achieve precise fitting of the positioning block 211 and the non-glue-dispensing area 20b. During the positioning process, the positioning block 211 can completely cover the non-glue-dispensing area 20b, ensuring that the pressure applied to the part to be glued 2 is evenly distributed, so that the non-glue-dispensing surface of the part to be glued 2 is tightly fitted with the bearing surface 110, thereby improving the positioning accuracy. In addition, the width of the positioning block 211 matches the width of the non-glue-dispensing area 20b, which can better protect the glue-dispensing area 20a. During the glue-dispensing process, the positioning block 211 only contacts the non-glue-dispensing area 20b and will not cause any interference or damage to the glue-dispensing area 20a.

[0065] In one possible embodiment, see Figure 4 The first positioning device 1 further includes a first driving structure 212 , which is connected to the positioning pressing block 211 and is used to drive the positioning pressing block 211 to move in a vertical direction.

[0066] The first driving structure 212 can accurately control the vertical movement of the positioning block 211. Through preset motion parameters such as speed, acceleration and stroke, it can ensure that the positioning block 211 accurately reaches the predetermined position and applies appropriate pressure, which helps to improve the positioning accuracy and stability and reduce dispensing errors.

[0067] In one possible embodiment, see Figure 4 , multiple positioning blocks 211 all have a pressing surface 2111, the pressing surface 2111 is used to press the part to be dispensed 2, and the multiple pressing surfaces 2111 are located in the same plane; the first driving structure 212 includes multiple first driving members 2121 and a first control member, the multiple first driving members 2121 correspond one-to-one to the multiple positioning blocks 211 and are respectively connected to the multiple positioning blocks 211, the multiple first driving members 2121 are all connected to the first control member, and the first control member is used to control the multiple first driving members 2121 to drive the multiple positioning blocks 211 to move synchronously in the vertical direction.

[0068] The plurality of pressing surfaces 2111 are located in the same plane. When the glued part 2 is pressed, it can ensure that the non-glue-dispensing surface of the glued part 2 and the bearing surface 110 are more evenly fitted, which helps to improve the flatness of the glued part 2 on the bearing surface 110, thereby providing a stable and precise basis for the glue dispensing operation. In addition, the first control part controls the plurality of first driving parts 2121 to drive the plurality of positioning pressing blocks 211 to move synchronously in the vertical direction, so that the pressure exerted by each positioning pressing block 211 on the glued part 2 is more consistent, further enhancing the glued part 2 on the bearing surface. The stability on the surface 110 reduces the displacement or deformation caused by uneven pressure during the dispensing process. For example, if the movements of different positioning blocks 211 are not synchronized, it may cause uneven force on the part to be dispensed 2, thereby causing the dispensing surface 20 to tilt, affecting the dispensing quality. In addition, the synchronous movement design can achieve rapid positioning. When the part to be dispensed 2 is placed on the supporting surface 110, multiple positioning blocks 211 can quickly and simultaneously approach the part to be dispensed 2 and press it under the unified control of the first control component, which greatly shortens the positioning time and improves production efficiency.

[0069] In a possible embodiment, the first driving member 2121 is a first driving cylinder, the first control member is a first solenoid valve, and the air inlets of a plurality of first driving cylinders are connected in parallel to the air outlet of the first solenoid valve.

[0070] When the first solenoid valve receives a control signal and opens, gas can quickly enter the first drive cylinder, causing the positioning block 211 to move rapidly in the vertical direction, achieving rapid positioning of the part 2 to be dispensed. Furthermore, the first drive cylinder can provide a relatively stable output force. By adjusting the air pressure in the first drive cylinder, the pressure of the positioning block 211 on the part 2 to be dispensed can be precisely controlled, ensuring that the non-dispensing surface and the support surface 110 are in close contact with each other while preventing damage to the part 2 due to excessive pressure. For example, for parts 2 to be dispensed of different materials and thicknesses, the air pressure can be adjusted according to actual conditions to achieve the best positioning effect. Furthermore, the first solenoid valve can precisely control the gas flow and pressure entering the first drive cylinder. By adjusting the opening of the solenoid valve, the cylinder movement speed and output force can be finely adjusted, thereby improving positioning accuracy. By connecting the air inlets of multiple first drive cylinders in parallel to the air outlet of the first solenoid valve, the first solenoid valve can synchronously control the multiple cylinders, ensuring the synchronization of the movement of the multiple positioning blocks 211 and improving positioning stability and consistency.

[0071] Of course, the first drive structure 212 is not limited to the above structure. For example, the first drive structure 212 can also be a combination structure of an electric push rod and a controller, using multiple electric push rods as driving parts, each electric push rod is connected to a positioning pressure block 211, and at the same time, equipped with a centralized controller as a control component, connected to multiple electric push rods; or, a combination structure of a servo motor and a transmission mechanism, using multiple servo motors as driving parts, each servo motor is connected to a positioning pressure block 211 through a transmission mechanism (such as a screw-nut mechanism, a gear rack mechanism, etc.), equipped with a motion controller as a control component, connected to multiple servo motors, and so on. Those skilled in the art should know this.

[0072] In one possible embodiment, see Figure 5 The positioning device 1 further includes a second driving structure 213, which is connected to the positioning pressing block 211 and is used to drive the positioning pressing block 211 to move in a horizontal direction.

[0073] The second driving structure 213 can accurately control the horizontal movement of the positioning block 211. Through preset motion parameters such as speed, acceleration and stroke, it can ensure that the positioning block 211 accurately reaches the predetermined position, which helps to improve the positioning accuracy and stability and reduce dispensing errors.

[0074] In one possible embodiment, see Figure 5, multiple positioning blocks 211 all have a pressing surface 2111, the pressing surface 2111 is used to press the part to be dispensed 2, and the multiple pressing surfaces 2111 are located in the same plane; the second driving structure 213 includes multiple second driving members 2131 and a second control member, the multiple second driving members 2131 correspond one-to-one to the multiple positioning blocks 211 and are respectively connected to the multiple positioning blocks 211, the multiple second driving members 2131 are all connected to the second control member, and the second control member is used to control the multiple second driving members 2131 to drive the multiple positioning blocks 211 to move synchronously in the horizontal direction.

[0075] The multiple pressing surfaces 2111 are located in the same plane. When pressing the part to be glued 2, it can ensure that the non-glue surface of the part to be glued 2 and the supporting surface 110 fit more evenly, which helps to improve the flatness of the part to be glued 2 on the supporting surface 110, thereby providing a stable and precise basis for the gluing operation. In addition, the second control component controls the multiple second driving components 2131 to drive the multiple positioning blocks 211 to move synchronously in the horizontal direction, so that the multiple positioning blocks 211 can quickly and simultaneously approach the part to be glued 2 under the unified control of the first control component, which greatly shortens the positioning time and improves production efficiency.

[0076] In a possible embodiment, the second driving member 2131 is a second driving cylinder, the second control member is a second solenoid valve, and the air inlets of a plurality of second driving cylinders are connected in parallel to the air outlet of the second solenoid valve.

[0077] By connecting the air inlets of the plurality of second driving cylinders in parallel to the air outlet of the second solenoid valve, the second solenoid valve can synchronously control the plurality of second driving cylinders, thereby ensuring the synchronization of the plurality of positioning blocks 211 during movement.

[0078] In one possible embodiment, see Figure 5 The positioning device 1 also includes a first driving cylinder fixing part 214 and a connecting member 215 slidingly arranged on the first driving cylinder fixing part 214 along the horizontal direction. The first driving cylinder fixing part 214 is connected to the first driving structure 212, and the second driving structure 213 is arranged on the first driving cylinder fixing part 214. Along the horizontal direction, one end of the connecting member 215 is connected to the second driving structure 213, and the other end is connected to the positioning block 211.

[0079] The first driving cylinder fixing part 214 is connected to the first driving structure 212 to realize the movement of the positioning pressure block 211 in the vertical direction. At the same time, the connecting member 215 is slidingly set on the first driving cylinder fixing part 214 in the horizontal direction and is connected to the second driving structure 213, so that the positioning pressure block 211 can be adjusted in the horizontal direction. The sliding of the connecting member 215 in the horizontal direction can realize the fine adjustment of the positioning pressure block 211, so that the positioning pressure block 211 can more accurately correspond to the non-glue area 20b of the part 2 to be glued.

[0080] In one possible embodiment, see Figure 6 The positioning structure 200 further includes a second positioning structure 220 , which is used to adsorb the part to be dispensed 2 onto the carrying surface 110 .

[0081] The second positioning structure 220 can adsorb the object 2 to be dispensed onto the carrying surface 110 by magnetic adsorption or vacuum adsorption, which is not limited here.

[0082] Therefore, in addition to the positioning achieved by the first positioning structure 210 through the positioning block 211, the adsorption effect of the second positioning structure 220 further enhances the fixing effect of the part to be dispensed 2 on the supporting surface 110. This dual positioning method makes the part to be dispensed 2 more stable during the dispensing process and is not prone to displacement or shaking. In addition, the adsorption force can be evenly distributed over the entire non-dispensing surface of the part to be dispensed 2 in contact with the supporting surface 110, so that the force on the part to be dispensed 2 is more uniform. Compared with simple mechanical positioning, this uniform force method can reduce local stress concentration and reduce the risk of deformation of the part to be dispensed 2 due to uneven force. For example, for thin or easily deformed bipolar plates, adsorption positioning can effectively maintain their shape and ensure the flatness of the dispensing surface 20.

[0083] Furthermore, when the part 2 to be dispensed is placed on the supporting surface 110, the second positioning structure 220 can quickly generate an adsorption force, quickly fixing the part 2 in the correct position. This significantly shortens positioning time and improves production efficiency. During the dispensing process, the adsorption force can continue to work, preventing the part 2 from accidentally falling off. In addition, compared with mechanical positioning methods, adsorption positioning causes less surface wear on the part 2 to be dispensed.

[0084] In one possible embodiment, see Figure 7 The second positioning structure 220 includes a sealed chamber vertically disposed below the carrying surface 110 , an adsorption hole 221 disposed on the positioning base 100 and communicating with the sealed chamber, and a negative pressure member communicating with the sealed chamber.

[0085] The sealed chamber is arranged below the bearing surface 110 in the vertical direction, and is connected to the adsorption hole 221 on the positioning base 100, so that the negative pressure can be evenly transmitted to the part to be dispensed 2 on the bearing surface 110, so as to ensure that the part to be dispensed 2 is stably adsorbed in the entire area where the non-dopant surface contacts the bearing surface 110, avoiding the occurrence of local weak adsorption or uneven force. During the dispensing process, the uniform adsorption force can prevent the part to be dispensed 2 from warping or deformation, thereby improving the accuracy and quality of dispensing. Moreover, when the negative pressure part is started, negative pressure is quickly formed in the sealed chamber, and the part to be dispensed 2 is quickly adsorbed through the adsorption hole 221. This rapid adsorption feature can greatly shorten the positioning time and improve production efficiency. The size of the adsorption force can also be adjusted by adjusting the parameters of the negative pressure part.

[0086] In one possible embodiment, see Figure 7 The adsorption holes 221 include multiple ones, and along the length direction of the positioning base 100, the multiple adsorption holes 221 are respectively arranged near the two ends and the middle of the positioning base 100.

[0087] The setting of multiple adsorption holes 221 allows the part to be glued 2 to be subjected to the adsorption force at different positions. Adsorption holes 221 are set at both ends and the middle along the length direction of the positioning base 100, respectively, so that the part to be glued 2 can be adsorbed and fixed from multiple positions, which greatly enhances the stability of adsorption. The adsorption holes 221 are distributed near the two ends and the middle of the positioning base 100, so that the adsorption force can act more evenly on the part to be glued 2. This evenly distributed adsorption force can prevent the part to be glued 2 from warping or deformation due to uneven force.

[0088] In one possible embodiment, see Figure 8 The positioning device 1 also includes a detection structure 300 and a third control component electrically connected to the detection structure 300. The third control component is electrically connected to the negative pressure component. When the detection structure 300 detects that the part to be dispensed 2 is located on the positioning base 100, the detection structure 300 is used to transmit a signal to the control component so that the control component controls the second positioning structure 220 to adsorb the part to be dispensed 2 onto the positioning base 100.

[0089] The part to be glued 2 is placed on the bearing surface 110 of the positioning base 100. At this time, the detection structure 300 starts to monitor the situation on the positioning base 100. Once the part to be glued 2 is detected, the detection structure 300 immediately transmits a signal to the third control component. After receiving the signal from the detection structure 300, the third control component processes and judges the signal, and controls the negative pressure component to start. The negative pressure component starts to work under the control of the third control component, so that negative pressure is formed in the sealed chamber, and the part to be glued 2 is adsorbed on the bearing surface 110 of the positioning base 100. The cooperation of the detection structure 300 and the third control component realizes the automatic operation of the positioning device 1. Without manual intervention, the system can automatically detect the position of the part to be glued 2 and start the adsorption function, thereby improving production efficiency and convenience of operation.

[0090] In a possible embodiment, a mounting groove 111 is provided on the bearing surface 110 ; the detection structure 300 includes a photoelectric sensor device, and the photoelectric sensor device is provided in the mounting groove 111 .

[0091] The photoelectric sensor device in this embodiment may be a diffuse reflection type photoelectric sensor, which is configured as a body with a transmitting end and a receiving end integrated together. The light emitted by the transmitting end is reflected by the workpiece 2 to be dispensed to the receiving end.

[0092] The photoelectric sensor device is arranged in the installation groove 111. When there is no part 2 to be dispensed, the light emitted by the transmitting end of the photoelectric sensor device cannot be reflected to the receiving end. Once the part 2 to be dispensed is placed on the supporting surface 110, the light emitted by the transmitting end can be reflected by the part 2 to be dispensed to the receiving end. For example, during the dispensing process, accurate detection can ensure that the positioning device 1 immediately starts the adsorption function after the part 2 to be dispensed is placed in place, thereby improving the timeliness and accuracy of positioning. In addition, setting the photoelectric sensor device in the installation groove 111 can avoid interference from external light and reduce the possibility of false detection.

[0093] Of course, the detection structure 300 is not limited to the above-mentioned form. For example, the detection structure 300 can also be a capacitive sensing detection structure 300, including a capacitive sensor probe and a detection circuit. The capacitive sensor probe is installed near or inside the bearing surface 110, and the detection circuit is connected to the capacitive sensor probe and performs signal processing; or an ultrasonic detection structure 300, consisting of an ultrasonic transmitter, an ultrasonic receiver and a signal processing unit. The ultrasonic transmitter and receiver are installed at different positions of the bearing surface 110, and the signal processing unit is connected to the receiver.
