Description

Technical Field

[0001] The invention relates to a detection device, in particular to a polar plate burr detection device for battery production verification. Background Art

[0002] With the development of science and production, deburring technology has received increasing attention. There are specialized research institutions in the world that conduct extensive research on the mechanism of burr generation, deburring and detection methods, and design of special tools.

[0003] Burrs are the extra parts of a workpiece produced during the manufacturing process. Different materials and processing methods of mechanical parts will produce different burrs. For example, burrs and residual materials are produced during the manufacturing process of castings, forgings, welds and plastic parts. There are also extra materials that appear on the surface or joints of parts during the cutting process.

[0004] There is no unified standard for evaluating the specifications of burrs and edges. The specific requirements for burrs and edges are rarely indicated during design. In the United States, SME (Society of Manufacturing Engineers) and ASME (American Society of Mechanical Engineers) have conducted in-depth research in this area, but have not formulated national standards. In order to evaluate the quality of deburring of the workpiece being tested, the industry basically refers to the evaluation rules of the parameter value range of surface roughness to classify the deburring quality.

Specific implementation mode

[0080] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0081] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0082] Please refer to Figures 1 to 17 , in an embodiment of the present invention, a burr detection device for battery production verification includes a detection platform 1. Two corner brackets 2 are fixed on both sides of the detection platform 1 respectively. The upper ends of the two corner brackets 2 are connected by a fixed platform 3. The fixed platform 3 is parallel to the detection platform 1. The two corner brackets 2 are respectively disposed on both sides of the fixed platform 3;

[0083] A surface finish measuring mechanism is provided on the fixed platform 3. The surface finish measuring mechanism can move back and forth along the length direction of the fixed platform 3. The surface finish measuring mechanism is used to verify the surface finish of the electrode plate placed at the detection station on the detection platform 1; A transmission structure is provided on the detection platform 1. The transmission structure is used to convey the electrode plate to be detected parallel to the length direction of the fixed platform 3 to the detection station on the detection platform 1; A driving structure is provided on the two corner brackets 2. The driving structure is connected to the transmission structure and the surface finish measuring mechanism.

[0084] In the embodiment of the present invention, the driving structure can drive the surface finish measuring mechanism to move back and forth alternately along the length direction of the fixed platform 3 on the fixed platform 3, and the driving structure can also drive the transmission structure to intermittently convey the electrode plate to be detected to the detection station on the detection platform 1;

[0085] Specifically, when the driving structure drives the surface finish measuring mechanism to move along the conveying direction of the transmission structure, the transmission structure is in a stationary state, while the surface finish measuring mechanism is in an open state and performs mobile detection on a plurality of electrode plates at the detection station; When it is detected that the surface finish of the electrode plate exceeds the specified value, the surface finish measuring mechanism issues an alarm, and the staff can remove the electrode plate that triggers the surface finish measuring mechanism to issue an alarm from the detection station;

[0086] When the driving structure drives the surface finish measuring mechanism to move against the conveying direction of the conveying structure, the conveying structure is in the conveying state, and the next batch of plates to be detected is conveyed to the detection station. At this time, the surface finish measuring mechanism is in the closed state.

[0087] As an embodiment of the present invention, the driving structure includes a servo motor 4, an output shaft 5, a transmission shaft 7, a transmission wheel 6, and a belt 8. The servo motor 4 is installed on one of the corner brackets 2.

[0088] The output shaft 5 passes through the corner bracket 2 where the servo motor 4 is installed and is connected to it through a bearing. One end of the output shaft 5 is connected to the output end of the servo motor 4. The transmission shaft 7 passes through the other corner bracket 2 and is connected to it through a bearing. The transmission shaft 7 is arranged at the same height as the output shaft 5. There are two transmission wheels 6, which are respectively fixedly installed on the transmission shaft 7 and the output shaft 5. The belt 8 connects the two transmission wheels 6, and the belt 8 is arranged along the length direction of the fixed platform 3.

[0089] In the embodiment of the present invention, the servo motor 4 in the present invention drives the transmission wheel 6 to rotate clockwise for a certain stroke and then rotate in the reverse direction for the same stroke through the output shaft 5, so that the belt 8 runs bidirectionally and alternately between the two transmission wheels 6.

[0090] It should be noted that the stroke of the belt 8 running alternately between the two transmission wheels 6 does not exceed the horizontal distance between the axes of the two transmission wheels 6.

[0091] As an embodiment of the present invention, the surface finish measuring mechanism includes a guiding and supporting component, an alarm structure, and a power connection structure. The guiding and supporting component is arranged on the fixed platform 3 and is connected to the belt 8. The alarm structure is installed on the guiding and supporting component. The alarm structure is used to give an alarm when it moves to a non-conforming plate. The power connection structure is arranged on the guiding and supporting component. The power connection structure is used to connect the alarm structure to power when the guiding and supporting component moves along the conveying direction of the conveying structure; and cut off the power of the alarm structure when moving against the conveying direction of the conveying structure.

[0092] In the embodiment of the present invention, since the stroke of the belt 8 running alternately between the two transmission wheels 6 does not exceed the horizontal distance between the axes of the two transmission wheels 6, the guiding and supporting component connected to the belt 8 can move back and forth along the length direction of the fixed platform 3 in the horizontal direction without vertical movement.

[0093] Driving the guiding and supporting component to move back and forth along the length direction of the fixed platform 3 through the belt 8 enables the alarm structure and the power connection structure installed and arranged on the guiding and supporting component to move back and forth accordingly. Moreover, when the alarm structure moves against the conveying direction of the conveying structure, the power connection structure cuts off its power to ensure that there is no alarm when conveying the product to be detected, and only alarms during detection, so as to separate detection and conveying.

[0094] As an embodiment of the present invention, the guiding and supporting assembly includes:

[0095] A moving member 9 fixed to the upper belt 8 and a connecting member 10 vertically fixed to the moving member 9. A through groove 11 for the connecting member 10 to pass through is formed in the fixed platform 3 along its length direction.

[0096] The guiding and supporting assembly further includes a mounting member 12, a supporting structure, and a stabilizing structure. The mounting member 12 is fixed to the top of the connecting member 10, and one side of the mounting member 12 extends along the width direction of the fixed platform 3 above the transmission structure; the alarm structure and the power connection structure are both arranged on the mounting member 12.

[0097] The supporting structure is arranged between the mounting member 12 and the fixed platform 3, and the supporting structure is used to support one side of the mounting member 12 extending above the transmission structure; the stabilizing structure is arranged between the connecting member 10 and the mounting member 12, and the stabilizing structure can keep the mounting member 12 parallel to the fixed platform 3.

[0098] In the embodiment of the present invention, when the belt 8 runs, it drives the moving member 9 and the connecting member 10 to move back and forth along the through groove 11, thereby driving the mounting member 12 to move back and forth accordingly.

[0099] The provided supporting structure can prevent the section of the mounting member 12 extending above the transmission structure from being bent and deformed under the action of gravity after the power connection structure and the alarm structure are installed.

[0100] The setting of the stabilizing structure can prevent an angle from being generated between the mounting member 12 and the fixed platform 3 due to jamming when the belt 8 drives the mounting member 12 to move back and forth along the through groove 11, ultimately causing the problem of instability of the power connection structure and the alarm structure.

[0101] As an embodiment of the present invention, the supporting structure includes a support shaft 16 rotatably arranged at the lower part of the mounting member 12 and a support wheel 17 fixed to the support shaft 16.

[0102] The axis of the support shaft 16 is parallel to the length direction of the mounting member 12; a card slot 15 that is in rolling fit with the support wheel 17 is formed in the fixed platform 3 along its length direction.

[0103] The rolling contact between the support wheel 17 and the card slot 15 can provide sufficient support force for the support shaft 16, and then the support shaft 16 provides support force for the mounting member 12 to prevent the section of the mounting member 12 extending above the transmission structure from being deformed and bent due to the gravity of the power connection structure and the alarm structure.

[0104] In addition, after the card slot 15 and the support wheel 17 are fitted together, the traveling direction of the support wheel 17 can be restricted to prevent the mounting member 12 from moving not along the length direction of the fixed platform 3. It should be noted here that although the connecting member 10 and the through groove 11 are fitted together, there is a gap between the connecting member 10 and the through groove 11 to reduce friction, so the guiding accuracy is very limited.

[0105] The stable structure includes two balance wheels 13 and a supporting wheel 14. The two balance wheels 13 are distributed along the length direction of the fixed platform 3, and the balance wheels 13 are rotatably mounted below the mounting member 12; the supporting wheel 14 is rotatably mounted on the connecting member 10, and the rotation centers of the two balance wheels 13 and the rotation center of the supporting wheel 14 are in the same plane and form a triangle;

[0106] Among them, the balance wheel 13 is in rolling fit with the upper surface of the fixed platform 3, and the supporting wheel 14 is in rolling fit with the lower surface of the fixed platform 3.

[0107] In the embodiment of the present invention, due to the provision of two balance wheels 13 and a supporting wheel 14, the connecting member 10 and the mounting member 12 can move stably on the fixed platform 3, and the rotation centers of the two balance wheels 13 and the rotation center of the supporting wheel 14 are in the same plane and form a triangle, so the mounting member 12 and the connecting member 10 will not generate vertical offset on the fixed platform 3.

[0108] As an embodiment of the present invention, the alarm structure includes an alarm 26, a pressure roller 27, a lifting rod 28, a compression spring 29, a top plate 30, a movable contact 31, and a fixed contact 32; the alarm 26 is electrically connected to the power supply through the movable contact 31 and the fixed contact 32;

[0109] The alarm 26 is fixedly mounted on the mounting member 12, and the pressure roller 27 is arranged between the mounting member 12 and the transmission structure; the lifting rod 28 is vertically and drivingly mounted on the mounting member 12 and is in sliding fit therewith, and the pressure roller 27 is rotatably arranged on the cross plate fixed at the lower end of the lifting rod 28; the compression spring 29 is sleeved on the lifting rod 28, and the upper end of the compression spring 29 abuts against the lower surface of the mounting member 12, and the lower end abuts against the cross plate; the top plate 30 is fixed at the upper end of the lifting rod 28, the movable contact 31 is mounted on the top plate 30, and the fixed contact 32 is mounted on the mounting member 12 and is adapted to the movable contact 31.

[0110] In the embodiment of the present invention, when verifying the battery plates, the surface smoothness of the plates is detected by the contact of the pressure roller 27 with the battery plates to be detected. When there are burrs on the plate surface, the pressure roller 27 moves upward, thereby driving the cross plate, the lifting rod 28 and the top plate 30 to move upward, compressing the compression spring 29, and the top plate 30 drives the movable contact 31 to contact the fixed contact 32, triggering the alarm 26 to alarm. At this time, the inspection personnel can remove the unqualified products from the stationary transmission structure.

[0111] As an embodiment of the present invention, the power connection structure includes an elastic switch 36, a rubber friction wheel 33, a swing arm 34, and a limit arm 37; the elastic switch 36 is electrically connected to the fixed contact 32 and the anode of the power supply; the rubber friction wheel 33 is rotatably installed on the outer periphery of the alarm 26 and is in contact with the upper surface of the fixed platform 3; the swing arm 34 is fixed to the edge of the rubber friction wheel 33, and a breaking block 35 that cooperates with the elastic switch 36 is installed on the swing arm 34;

[0112] The limit arm 37 is fixed to the side wall of the rubber friction wheel 33, and a limit wheel 38 that can rollingly cooperate with the upper surface of the fixed platform 3 is rotatably installed at the end of the limit arm 37.

[0113] In the embodiment of the present invention, when the belt 8 drives the mounting member 12 to move from one end closest to the servo motor 4 to the other end away from the servo motor 4 through the movable member 9 and the connecting member 10, the mounting member 12 drives the alarm structure to move accordingly; since the rubber friction wheel 33 is in contact with the upper surface of the fixed platform 3, the rubber friction wheel 33 rotates, causing the power-off block 35 to separate from the elastic switch 36. At this time, the fixed contact 32 is connected to the anode of the power supply, that is, a circuit is formed among the alarm 26, the movable contact 31, the fixed contact 32, and the power supply. As long as the movable contact 31 is combined with the fixed contact 32, the alarm 26 will work;

[0114] When the rubber friction wheel 33 rotates until the limit wheel 38 on the limit arm 37 is fixedly in contact with the upper surface of the fixed platform 3, under the action of the limit arm 37, the rubber friction wheel 33 stops rotating and instead slides on the upper surface of the fixed platform 3 to keep the power-off block 35 separated from the elastic switch 36, that is, to keep the fixed contact 32 connected to the anode of the power supply; in this way, it is realized that the fixed contact 32 is kept connected to the anode of the power supply during the process of the alarm structure moving from the end close to the servo motor 4 to the end away from the servo motor 4; achieving the alarm structure being in the startup state;

[0115] When the belt 8 drives the mounting member 12 to move from the end away from the servo motor 4 to the end close to the servo motor 4, the rubber friction wheel 33 rotates in the reverse direction. After the power-off block 35 on the swing arm 34 contacts the elastic switch 36, the rubber friction wheel 33 stops rotating and keeps the power-off block 35 in contact with the elastic switch 36, that is, the fixed contact 32 is disconnected from the anode of the power supply, so that the alarm structure is kept in the off state during the process of moving from the end away from the servo motor 4 to the end close to the servo motor 4.

[0116] During the process of the alarm structure moving from one end close to the servo motor 4 to the other end away from the servo motor 4, the alarm structure is in the activated state, while the transmission structure does not work, so as to enable the alarm structure to detect a plurality of stationary plates. When defective products are detected, the staff can remove them from the non-working transmission structure;

[0117] During the process of the alarm structure moving from one end away from the servo motor 4 to the other end close to the servo motor 4, the alarm structure is in the closed state, while the transmission structure works, so as to automatically convey the next batch of plates to be detected to the detection station, and no alarm will be issued during the process of conveying the plates to be detected, avoiding accidents caused by the staff accidentally taking defective products from the operating transmission structure.

[0118] As an embodiment of the present invention, the transmission structure includes two conveying rollers 24, a conveyor belt 25, a conveying shaft 23, and a one-way transmission structure, which are rotatably arranged at the same height on the detection platform 1;

[0119] The conveyor belt 25 is arranged between the two conveying rollers 24, and a plurality of separating ribs for separating adjacent plates are equidistantly arranged on the conveyor belt 25; the conveying shaft 23 is fixed to the side of one of the conveying rollers 24; the one-way transmission structure connects the conveying shaft 23 and the transmission shaft 7.

[0120] When the belt 8 drives the movable member 9, the connecting member 10, and the mounting member 12 to move towards the end away from the servo motor 4, the one-way transmission structure remains stationary, so that the conveying shaft 23, the conveying roller 24, and the conveyor belt 25 are stationary, that is, when the alarm structure detects the plates on the conveyor belt 25, the conveyor belt 25 is stationary;

[0121] When the belt 8 drives the mounting member 12 to move towards the end close to the servo motor 4, the one-way transmission structure remains working, driving the conveying shaft 23 and the conveying roller 24 to rotate, so that the plates on the conveyor belt 25 approach the fixed platform 3, that is, when the alarm structure is closed, the conveyor belt 25 runs to convey the next batch of plates to be detected to the detection station.

[0122] As an embodiment of the present invention, the one-way transmission structure includes a ratchet 18, a rotating shaft 21, a one-way wheel 19, and a transmission belt 22. The ratchet 18 is fixed to the end of the transmission shaft 7; the rotating shaft 21 is rotatably installed on the detection platform 1; a plurality of recessed parts are circumferentially and equidistantly arranged on the edge of the one-way wheel 19, and a pawl 20 for cooperating with the ratchet 18 is rotatably installed on the recessed part; the transmission belt 22 connects the rotating shaft 21 and the conveying shaft 23.

[0123] In an embodiment of the present invention, when the belt 8 drives the movable member 9, the connecting member 10, and the mounting member 12 to move towards one end away from the servo motor 4, the transmission shaft 7 drives the ratchet wheel 18 to rotate.
