Description

Technical Field

[0001] The utility model belongs to the field of automatic testing equipment, and in particular relates to a probe alternating driving mechanism and a laser induced sintering device. Background Art

[0002] In the field of industrial processing and mechanical manufacturing, the requirements for production capacity are getting higher and higher. Increasing production capacity requires the motion mechanism to have a faster motion cycle. For application scenarios that require the use of an alternating clamping mechanism, especially in certain high-speed motion automation fields, the accuracy and timeliness (response rate) of alternating clamping are often related to the quality of processing and testing, and therefore have received more and more attention and research.

[0003] There are many mechanisms that can achieve alternating clamping, such as horizontally supplying a cylinder or motor, and longitudinally supplying a cylinder or motor. Alternating clamping can be achieved by controlling the cylinder and the motor. A power is split for each direction of movement, and the predetermined actions can be completed in sequence by controlling the timing of the power. This method is simple in design and can meet the needs of practical applications to a certain extent. However, the above method also has obvious disadvantages. The biggest problem is that its application cost is relatively high, and the control of related equipment and mechanisms is complex. The accuracy and timeliness in actual use cannot fully meet the needs of various industries to increase production capacity. Utility Model Content

[0049] Example:

[0050] See also Figure 1~Figure 5 The probe alternating driving mechanism in the preferred embodiment of the utility model includes a driving component 2 and a probe component 4.

[0051] The driving assembly 2 includes a cam driving mechanism 205, a camshaft 102 connected to the cam driving mechanism 205, a left cam 201 and a right cam 202 connected to the camshaft 102, a left swing arm 203 arranged in contact with the left cam 201, and a right swing arm 204 arranged in contact with the right cam 202. The contact arrangement here means that the cam is always in contact with the swing arm corresponding to the cam, so that when the cam moves under the drive of the cam driving mechanism 205, the swing arm is driven by the cam to move so as to drive the probe mechanism to move.

[0052] Meanwhile, the probe assembly 4 includes a left probe mechanism 401 corresponding to the left swing arm 203 and a right probe mechanism 402 corresponding to the right swing arm 204. The corresponding arrangement here means that in terms of spatial position, the position arrangement of the left swing arm 203 can drive the left probe mechanism 401 to move, and the position arrangement of the right swing arm 204 can drive the right probe mechanism 402 to move.

[0053] Correspondingly, a displacement assembly 3 is also provided corresponding to the action process of the two probe mechanisms, which includes a left displacement assembly and a right displacement assembly. The left probe mechanism 401 and the right probe mechanism 402 are connected to the left displacement assembly and the right displacement assembly respectively, and the left displacement assembly and the right displacement assembly both include a transverse guide rail 302 extending in a first direction in a horizontal plane and a longitudinal guide rail 301 provided in a vertical direction.

[0054] It should be noted that the first direction is Figure 1 The Y-axis direction is shown, and the vertical direction is Figure 1 The Z-axis direction is shown.

[0055] In addition, one end of the left swing arm 203 and the right swing arm 204 are both active ends, acting on the outer edges of the corresponding cams, specifically, the active end of the left swing arm 203 acts on the outer edge of the cam of the left cam 201, and the active end of the right swing arm 204 acts on the outer edge of the cam of the right cam 202; and the other ends of the left swing arm 203 and the right swing arm 204 are both follower ends, used to drive the corresponding probe mechanisms to move in the first direction and the vertical direction under the guidance of their respective displacement components.

[0056] By utilizing the combined arrangement of the above components and switching the contact positions of the two swing arms with the corresponding cams, the alternating displacement control of the two probe mechanisms can be realized, thereby completing the alternating driving of the probe mechanisms.

[0057] Since the probe alternating drive mechanism of the present application can realize the alternating downward pressing and lateral movement of the two probe mechanisms with only one driving power (cam drive mechanism), the probe alternating pressing effect can be achieved at a relatively low cost, which reduces the cost and the control requirements. In addition, the probe mechanism has a short alternating time, adopts a cam-connecting rod mechanical transmission mode, has a compact structure, and is highly reliable.

[0058] Preferably, in actual configuration, the corresponding drive assembly 2 is designed with a frame 1, such as Figure 1 As shown in the figure, a swing arm shaft 101 and the above-mentioned cam shaft 102 are arranged in parallel on the frame 1, the swing arm shaft 101 is fixedly connected to the frame 1 for rotational assembly with two swing arms, and the cam shaft 102 is rotationally connected to the frame 1 for fixed arrangement with two cams.

[0059] In actual setting, the camshaft 102 extends along the first direction, and the left cam 201 and the right cam 202 are spaced apart in the first direction; the camshaft 102 is driven by the cam driving mechanism 205, so that the camshaft 102 rotates, thereby driving the left cam 201 and the right cam 202 to rotate, and finally driving the left swing arm 203 and the right swing arm 204 to reciprocate. Specifically, in an embodiment of the present application, the left swing arm 203 and the right swing arm 204 reciprocate in the vertical direction.

[0060] In a preferred embodiment, in order to ensure the reliability of the action between the swing arm and the outer edge of the cam, an action wheel 2031 whose outer edge always abuts against the outer edge of the cam is provided at the end of the active end of the swing arm.

[0061] At the same time, in a specific preferred embodiment, the cam drive mechanism 205 is a servo motor, and a reducer and a coupling are correspondingly arranged therein, and the three are connected in sequence and connected to the end of the camshaft 102, thereby realizing the accurate driving of the camshaft 102 and the cam on the camshaft 102.

[0062] In more detail, the left probe mechanism 401 and the right probe mechanism 402 in the preferred embodiment both include a bracket, a displacement rod 403 connected to the bracket, a linear bearing 404 sleeved on the displacement rod 403, and at least one row of probes 406 connected to the bracket.

[0063] The displacement rod 403 is extended along the first direction, close to the follower end of the corresponding swing arm, and the probe row 406 is relatively far away from the corresponding follower end. The follower ends of the two swing arms rotate around the center of the swing arm shaft 101 during operation, and the ends are lifted and lowered vertically (longitudinally). Furthermore, in order to ensure the accuracy of the movement of the displacement assembly 3, an open groove 2032 is respectively provided on each follower end, and the two follower ends respectively fork the corresponding linear bearing 404 with their open grooves 2032, so that the linear bearing 404 can reciprocate in the open groove 2032 along the first direction.

[0064] In actual settings, in order to ensure the reliability of the swing arm movement, it is necessary to ensure that its active end is always in contact with the outer edge of the cam. To this end, force-applying members are respectively provided for the two swing arms, which act on the swing arms and ensure that the active end of the swing arm always acts on the outer edge of the cam, thereby ensuring the accuracy of the probe assembly 4 following the movement of the cam. In actual settings, the setting of the force-applying member can be changed as needed, such as a tension spring provided between the active end of the swing arm and the cam slot plate 103 below, a compression spring provided between the cam slot plate 103 and the follower end of the swing arm, or by opening a groove (limiting) in the cam.

[0065] Further, the probe assembly 4 in the preferred embodiment is as follows Figure 1 As shown in , the left probe mechanism 401 and the right probe mechanism 402 respectively include a bracket and at least one row of probe rows 406 connected to the bracket, and the probe rows 406 are extended along a second direction (the X-axis direction in the figure), and the second direction is perpendicular to the first direction. Figure 1 As shown, in this embodiment, the number of probe rows 406 on each probe mechanism is one row, which is helpful to solve the problem of the probe mechanism blocking the laser.

[0066] In more detail, Figure 2As shown, the left probe mechanism 401 and the right probe mechanism 402 each include two rows of probe rows 406 spaced apart in the first direction, and two adjacent probe rows 406 in the two probe mechanisms are staggered, which is equivalent to the two probe mechanisms being arranged across each other on the sides close to each other. In a preferred embodiment, the bracket of the probe mechanism is a square frame structure, and each probe row 406 is extended along the second direction and arranged at the bottom of the bracket. At this time, the objects contacted by the probes are preferably two half-sheets, and the two rows of probe rows 406 on one probe mechanism contact the two half-sheets respectively, so that the two half-sheets can be processed at the same time, so that the alternating compression of the two half-sheets at two different positions in the first direction can be achieved at the same time.

[0067] Further preferably, in order to ensure the reliability of the motion guidance of the two probe mechanisms, the probe alternating driving mechanism preferably further includes a cam slot plate 103 arranged on the side of the two probe mechanisms along the second direction, that is, a cam slot plate 103 is arranged on one side of the two probe mechanisms along the second direction. Figure 6 As shown in , the second direction is perpendicular to the first direction, the length direction of the cam slot plate 103 is parallel to the first direction, and two limiting holes 104 are provided on the cam slot plate 103 corresponding to the two probe mechanisms of the probe assembly 4. Accordingly, limiting posts 405 are respectively provided on the two probe mechanisms, one end of which is connected to the probe mechanism, and the other end is assembled and connected to the corresponding limiting holes 104, that is, the two limiting holes 104 are provided in a one-to-one correspondence with the two limiting posts 405, and the setting of the limiting holes 104 is used to accurately limit the position starting points of the two probe mechanisms in the first direction and the longitudinal movement direction.

[0068] In a specific preferred embodiment, the limiting hole 104 includes an arc-shaped hole, which is further preferably a combination of an arc-shaped hole segment and a vertical hole segment, such as Figure 6 As shown in , this ensures that when the probe mechanism needs to move in both the first direction and the vertical direction, the movement process is smoother.

[0069] In actual setting, in order to cooperate with the translational movement of the probe mechanism in the first direction, a transverse guide rail 302 is provided in the displacement assembly 3 in the preferred embodiment, which is extended along the first direction and connected to the cam slot plate 103. Accordingly, the longitudinal guide rail 301 is assembled and connected to the transverse guide rail 302, so that the probe mechanism assembled and connected to the longitudinal guide rail 301 can perform reciprocating displacement in the first direction under the guidance of the transverse guide rail 302.

[0070] When the probe assembly 4 is actually working, it often needs to cooperate with other equipment or mechanisms, such as a processing mechanism set above the probe assembly 4. At this time, if the pressing operation of the probe mechanism is performed in a "straight up and straight down" manner, it will still block the workpiece below the probe mechanism. Therefore, with the above-mentioned setting of the limit hole 104 and related structures, the probe mechanism can be translated a certain distance in the first direction after lifting, thereby removing the obstruction of the workpiece by the probe mechanism, and the downward pressing method of this structure is compact and has higher work efficiency.

[0071] In actual operation, the two probe mechanisms work alternately. Specifically, the pressing and lifting of the two probe mechanisms are not performed simultaneously. The two probe mechanisms realize the alternate pressing of different workpieces or the alternate pressing of different parts of the same workpiece in an alternating manner.

[0072] In such Figure 7 In the preferred embodiment shown, the left probe mechanism 401 and the right probe mechanism 402 driven by the left cam 201 and the right cam 202 are arranged to be pressed alternately. To achieve the above purpose, when two cams are arranged on the camshaft 102, the two cams need to be arranged to be circumferentially offset, that is, the initial fixed state of the right cam 202 on the camshaft 102 is rotated by a certain angle compared with the initial fixed state of the left cam 201, for example Figure 7 The angle of the circumferential misalignment shown in is 90°.

[0073] The two cams are arranged in an circumferentially staggered manner on the outer periphery of the camshaft 102, so that the operation process actually experienced by the two cams is performed in an alternating manner. In a preferred embodiment, the specific shapes of the two cams are preferably the same, and each has an annular closed curve profile.

[0074] In more detail, the curved profile of the cam includes a small-diameter arc outer edge, a large-diameter arc outer edge, and two sections of variable-diameter curved outer edges connected therebetween. By setting up four sections of outer edges, the rotation of the cam can be converted into four movement stages of the probe mechanism: lifting, high-position rest, pressing down, and low-position rest.

[0075] Among them, the outer diameter of the curve contour corresponding to the high-position rest stage is the smallest, the outer diameter of the curve contour corresponding to the low-position rest stage is the largest, the outer diameter of the curve contour corresponding to the lifting stage changes from large to small, and the outer diameter of the curve contour corresponding to the pressing stage changes from small to large.

[0076] More preferably, in actual setting, the clamping angles corresponding to the four-segment curve profile are 90° respectively, and the time experienced by the four stages is the same when the cam speed is kept constant. It should be noted that the clamping angles corresponding to the four-segment curve profile may not be 90°, that is, the clamping angles corresponding to the four-segment curve profile may be different. For example, according to implementation requirements, when the processing time is long, the clamping angle corresponding to the rest stage can be increased, and the assumed angles corresponding to other stages can be reduced.

[0077] It should be noted that Figure 7 The lifting, high-position rest, pressing down, and low-position rest all refer to the movement of the two probe mechanisms. For example, pressing down means controlling the probe to move downward until it contacts the battery cell below; lifting means controlling the probe to leave the battery cell so that it no longer contacts the battery cell and does not block the laser; high-position rest means that the probe does not contact the battery cell continuously; and low-position rest means that the probe continues to press down on the battery cell.

[0078] The above cam curve can make the movement displacement, movement speed and even acceleration of the probe mechanism smooth. With continuous and smooth speed characteristics, rigid impact can be avoided and damage to the workpiece (battery cell) can be reduced.

[0079] In a preferred embodiment, following the rotation of the camshaft 102, the two cams respectively perform four stages of lifting, high-position stop, pressing down, and low-position stop in sequence, and the right cam 202 and the left cam 201 are staggered so that the left probe mechanism 401 and the right probe mechanism 402 are pressed down alternately. The specific working process is as follows:

[0080] Assume that the left probe mechanism 401 first enters the high-position resting state from the lifting state (the left probe mechanism 401 is away from the battery cell below it), and then the right probe mechanism 402 begins to enter the pressing state, such as Figure 7 Meanwhile, if necessary (for example, the processing time is long), when the left probe mechanism 401 is away from the battery cell and the right probe mechanism 402 is pressing the battery cell, the laser scanning process of the left area of ​​the battery cell can be completed accordingly.

[0081] Then both cams rotate 90°, the left probe mechanism 401 first remains in a high-position resting state for a while and then starts to move horizontally downward to press the battery cell below, while the right probe mechanism 402 is in a low-position resting state (that is, the right probe mechanism 402 presses the battery cell and does not move); when the left probe mechanism 401 moves away from the battery cell and the right probe mechanism 402 presses the battery cell, the laser scanning process of the left area of ​​the battery cell can be completed accordingly.

[0082] Then both cams continue to rotate 90°, and the left probe mechanism 401 changes to a low-position resting state (that is, the left probe mechanism 401 presses the battery cell and does not move), and the right probe mechanism 402 performs an upward lifting action (that is, the right probe mechanism 402 starts to move away from the battery cell). It should be noted that the right probe mechanism 402 continues to move away from the battery cell for a period of time after being lifted up in this process. If necessary, this period of time in which the left probe mechanism 401 presses and the right probe mechanism 402 moves away from the battery cell can also be used to perform a laser scanning process of the right area not blocked by the right probe mechanism 402.

[0083] Then both cams continue to rotate 90°, and the left probe mechanism 401 maintains a low-position rest state for a period of time and then changes to an upward state. The left probe mechanism 401 is released from contact with the battery cell, and the right probe mechanism 402 is in a high-position rest state (that is, the right probe mechanism 402 is always away from the battery cell). In the process of the left probe mechanism 401 pressing the battery cell and the right probe mechanism 402 being away from the battery cell, the laser scanning process of the area on the right side of the battery cell that is not blocked by the right probe mechanism 402 can be completed.

[0084] At the end of the above state, both the left and right sides of the battery cell are not held by the probe mechanism. After the laser scanning on the right side of the battery cell is completed, the processed battery cell can be transferred away by the conveying mechanism and a new battery cell can be transferred again for repeated processing.

[0085] As the camshaft 102 cycles, the above process is cyclically performed in sequence.

[0086] By repeatedly performing the above process, at least the alternating pressing of two different parts of a single workpiece located below the probe assembly 4 and extending a certain length in the first direction in the first direction can be achieved, and the left and right sides of the single workpiece are not blocked by the probe mechanism, thereby providing conditions for laser scanning on the left and right sides of the battery cell.

[0087] As another aspect of the present invention, a laser induced sintering device (not shown in the figure) is also provided, which includes the aforementioned probe alternating drive mechanism, and in addition, also includes a supporting component for supporting the battery cell and a laser processing component.

[0088] Among them, the carrying component is arranged below the probe component 4, and is used to carry the battery cell to be processed; the laser processing component is arranged above the probe component 4, which includes a laser for emitting a laser beam and a laser scanning mechanism (such as a galvanometer plus a field mirror) for controlling the scanning direction of the emitted laser beam. The laser processing component can scan and process the corresponding battery cell (part) when one of the probe mechanisms is in a high-position stop stage, and scan and process the battery cell (part) corresponding to the other probe mechanism after the other probe mechanism is lifted and stopped.

[0089] More specifically, when the left probe mechanism 401 is in the first area (the left part of the cell) of the cell pressed and the right probe mechanism 402 is in the lifted state, the laser processing assembly can perform laser scanning on the second area of ​​the cell; when the right probe mechanism 402 is in the second area (the right part of the cell) of the cell pressed and the left probe mechanism 401 is in the lifted state, the laser processing assembly can perform laser scanning on the first area of ​​the cell. The first area is different from the second area (that is, the areas of the cell contacted by the left probe mechanism 401 and the right probe mechanism 402 are different, so as to solve the problem of the probe mechanism blocking the laser).

[0090] It should be noted that, since the two probe mechanisms in the present application can not only be lifted but also translated a certain distance in the first direction, the probe mechanisms can stay at a position that does not block the laser when in the high-position rest stage.

[0091] Furthermore, the sum of the two laser scanning areas is preferably the entire cell surface area, and the probe group can avoid blocking the laser scanning cell by the different positions where the probe contacts the cell twice and the different laser scanning areas.

[0092] The above-mentioned laser induced sintering device, combined with the probe alternating driving mechanism, can complete the laser induced sintering process of the battery cell at one station, which can not only solve the problem of laser shielding by the probe mechanism at one station, but also has a high processing rate.

[0093] By utilizing the corresponding settings and operation of the alternating clamping mechanism, the laser processing assembly can perform alternating processing on different parts of the cell, avoiding the probe mechanism from blocking the cell to be processed, while ensuring the use efficiency of the laser processing assembly and improving the photoelectric conversion efficiency of the cell.

[0094] The probe alternating drive mechanism in the utility model has a compact structure, high reliability, and accurate control. It can achieve the effect of alternating pressing of the probe mechanism at a relatively low cost, which reduces the cost and the control requirements at the same time. It can also realize lateral displacement of the probe mechanism during the alternating pressing process, ensuring that the probe mechanism releases the obstruction of the workpiece when the workpiece is not pressed, providing conditions for the setting and implementation of other processing procedures of the workpiece, improving the processing efficiency and quality of the workpiece, and has good practical value and application prospects.

[0095] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
