Description

Technical Field

[0001] This invention relates to the field of electrical variable detection technology, and more particularly to a microneedle module testing device for batteries. Background Technology

[0002] In the battery manufacturing process, battery performance testing is a key step in ensuring product quality and safety. This step ensures that battery products meet design standards and safety specifications, guarantee their stability during subsequent use, and promptly screens out unqualified products to avoid safety hazards or economic losses caused by battery performance defects.

[0003] The traditional battery testing method works as follows: a testing device consisting of a test fixture, a female connector, and a battery connector is typically used. The working principle is to fasten the battery connector to the test female connector to form a stable physical connection. Then, the test fixture is pressed down to make the test pins contact the pins of the female connector. Through the conduction effect between the female connector and the connector, a test circuit is constructed, thereby realizing the testing of various performance parameters of the battery.

[0004] While this testing method can meet basic testing requirements, it has certain technical drawbacks in practical applications: during the testing process, the micro-needles on the female connector need to engage with the connector pins, which causes mechanical wear between the micro-needles and the pins. This not only shortens the lifespan of the female connector (usually only able to maintain about 200 tests), but also damages the connector of the battery product itself, affecting the subsequent performance of the battery.

[0027] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0028] Example: Combining Figure 4 and Figure 5 As shown, the battery 001 integrates a connector 002, a connecting wire 003, a pin 004, and a solder area 005. One end of the connecting wire 003 is fixedly connected to the battery 001, and the other end is firmly connected to the connector 002, thus establishing a stable electrical path between the two. The pin 004 is soldered to one side of the connector 002, and the solder area 005 is the solder joint area formed when the pin 004 is soldered and fixed. It surrounds the pin 004 and realizes electrical conduction.

[0029] A battery microneedle module testing device, combined with Figures 1-2As shown, it includes: a base 101; a conveying device 102 fixedly installed on the left side of the base 101 for continuously conveying the battery 001 to be tested to the base 101; a transfer device 103 fixedly installed at the rear of the base 101, the transfer device 103 consisting of an electrically controlled rail and a seat mounted thereon, the electrically controlled rail controlling the left and right displacement of the seat; and an adsorption device 104 fixedly installed on the seat of the transfer device 103 for adsorbing the battery 001, and having an adsorption control function. 3. The displacement of the adsorption device 104 is controlled to realize the transfer function of the battery 001; the test device 105 is fixedly installed on the left side of the base 101, and the test pins 106 are fixed on it and can be controlled to make vertical displacement of the test pins 106; the transfer disk 107 is rotated and installed on the base 101, and its intermittent stop rotation is controlled by the base 101; the recording device 108 is fixedly installed on the right side of the base 101 for taking pictures and recording the battery 001, so as to carry out subsequent traceability work. Combination Figures 3-5 As shown, the device also includes: a feeding trough 201 fixedly installed on the transfer plate 107, with two troughs per group, and a total of four groups of feeding troughs 201 on the transfer plate 107. When the transfer plate 107 rotates, it will drive these four groups of feeding troughs 201 to pass sequentially and cyclically under the adsorption device 104, the recording device 108, and the testing device 105. Specifically, the side of the feeding trough 201 closest to the rotation axis of the transfer plate 107 is defined as the inner side, and the other side is the outer side; a female seat 202 fixedly installed on the outer side of each feeding trough 201, with a row of pins 203 on the female seat 202. When the detection pin 106 moves downward, it will... Electrical contact is achieved by forming an electrical connection with pin 203. The female connector 202 is provided with a mating interface for docking connector 002. The periphery of the mating interface is provided with an arc-shaped guide surface to guide the position of connector 002. The auxiliary connector 002 is fastened to the mating interface. Two rows of micro pins 204 are slidably installed in the mating interface of the female connector 202. When connector 002 is fastened to the mating interface, the position of micro pin 204 corresponds to the position of solder area 005, and electrical connection is formed when it contacts solder area 005. A first return spring 205 is fixedly installed between the female connector 202 and the micro pins 204 and is sleeved on the micro pins 204.

[0030] Combination Figure 6 As shown, the device also includes: a mounting block 206 fixedly mounted on the mounting portion of the detection pin 106; a pressing arm 207 slidably mounted on the mounting block 206 for pressing the connector 002 to engage with the micro needle 204, the pressing arm 207 being positioned lower than the detection pin 106; and a second return spring 208 fixedly mounted between the pressing arm 207 and the mounting block 206, which is sleeved on the sliding shaft of the pressing arm 207.

[0031] The conveying device 102 operates, continuously conveying the battery 001 to be tested to the base 101, providing a continuous supply of objects to be tested for the testing process. The transfer device 103 operates synchronously, controlling the adsorption device 104 to move back and forth left and right via an electronically controlled track. When the adsorption device 104 moves to the leftmost end, it is above the conveying device 102. The adsorption device 104 moves down and adsorbs the battery 001 to be tested, then moves up to return to its original position. Subsequently, the transfer device 103 moves the adsorption device 104 to the right, transferring the battery 001 to the top of the discharge trough 201 of the transfer tray 107. After the transfer tray 107 stops intermittently, the adsorption device 104 moves down and releases the adsorption, accurately placing the battery 001 into the discharge trough 201, completing the automatic feeding of the battery 001. As the transfer tray 107 rotates, it moves the discharge trough 201 carrying the battery 001 to below the recording device 108. During the intermittent stops of the transfer tray 107, the recording device 108 takes pictures and records the battery 001 to retain data for subsequent traceability work. Then, the transfer tray 107 continues to rotate, bringing the battery 001 to below the testing device 105. During another intermittent stop, the testing device 105 operates to perform the testing process: the testing device 105 controls the detection pins 106 to move vertically downwards. During this process, the pressing arm 207 first contacts the connector 002, pushing the connector 002 to engage at the interface of the female connector 202, causing the micro-needle 20... 4. The solder area 005 around the connector 002 is connected. At the same time, the micro needle 204 is pushed downward, the first return spring 205 is compressed, the pressing arm 207 is displaced relative to the mounting block 206, and the second return spring 208 is compressed. The first return spring 205 and the second return spring 208 cooperate to finally enable the micro needle 204 and the connector 002 to achieve a stable electrical path. Finally, when the detection pin 106 contacts the pin point 203, the testing device 105 can form a stable electrical path with the connector 002 through the detection pin 106, pin point 203, micro needle 204 and solder area 005 to perform relevant electrical performance tests on the battery 001. After the test is completed, the testing device 105 controls the test pin 106 to move upward and return to its original position, the pressing arm 207 follows suit and resets, the second reset spring 208 self-recovers, and after the connector 002 separates from the pressing arm 207, the first reset spring 205 pops the connector 002 out of the interface, thereby releasing the electrical connection between them. Then, the transfer tray 107 rotates, transferring the tested battery 001 back to the corresponding position of the loading station. At this time, the adsorption device 104 starts again, adsorbs the tested battery 001 and is controlled to move to the right, releasing the battery 001 on the right side of the base 101, realizing the unified collection of the tested batteries 001. Finally, the adsorption device 104 moves to the left above the conveying device 102, ready to adsorb new batteries 001 to be tested, thus completing a complete battery 001 testing cycle. By repeating the above process, the automated and streamlined testing of battery 001 can be achieved.

[0032] Combination Figure 1 , Figure 7 and Figure 8 As shown, this equipment also includes: an adjustment mechanism mounted on the base 101, used to adjust the position of the battery 001 after it is fed into the machine. The adjustment mechanism includes: a push plate 301 slidably mounted on the inner side of each feeding slot 201, used to push the battery 001 to move towards the female seat 202; a third return spring 302 fixedly mounted between the feeding slot 201 and the push plate 301, which is sleeved on the sliding shaft of the push plate 301; and an arc-shaped connecting block 303 fixedly mounted on the end of the push plate 301. In the two feeding slots 201 of the same group, each of them... The arc-shaped connecting blocks 303 are staggered in height; the mounting frame 304, which is fixedly installed on the base 101, is positioned downstream of the adsorption device 104 with the rotation direction of the transfer disk 107 as the reference. That is, during the rotation of the transfer disk 107, the discharge trough 201 will pass through the adsorption device 104 and the mounting frame 304 in sequence; the two arc-shaped push blocks 305, which are fixedly installed on the mounting frame 304, are also staggered in height and correspond to the arc-shaped connecting blocks 303 on the two discharge troughs 201 of the same group.

[0033] As battery 001 is fed into the discharge trough 201 and transferred from the adsorption device 104 to the recording device 108, the discharge trough 201 carries battery 001 through the mounting frame 304. Two staggered arc-shaped push blocks 305 on the mounting frame 304 contact the corresponding arc-shaped receiving blocks 303 on the two discharge troughs 201. With the help of the rotational power of the transfer disk 107, the arc-shaped push blocks 305 exert a pushing force on the arc-shaped receiving blocks 303, controlling the push plate 301 to push battery 001 towards the female seat 202. The third return spring 302 is... The compression ensures that the position of battery 001 is adjusted so that connector 002 is directly above the interface on the female seat 202, thus achieving automatic adjustment of the position of battery 001. After the discharge chute 201 leaves the mounting frame 304, the arc-shaped push block 305 gradually separates from the arc-shaped connecting block 303, and the third reset spring 302 restores its deformation and drives the push plate 301 to move in the opposite direction, eventually returning to the initial position. The arc-shaped connecting block 303 and the arc-shaped push block 305 adopt a staggered fit design to avoid interference between them on the movement trajectory, ensuring the stability and smoothness of the adjustment operation.

[0034] Combination Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, the device also includes: a limiting mechanism disposed on the outside of each discharge trough 201, which is disposed between the female seat 202 and the discharge trough 201, for limiting the connecting line 003 and the connector 002. Each discharge trough 201 is provided with a set of limiting mechanisms. Each set of limiting mechanisms includes: a mounting shell 401 fixedly installed on the discharge trough 201; a pad 402 slidably installed on the mounting shell 401, which is horizontally displaced along the width direction of the mounting shell 401 to support and limit the connecting line 003; a connecting rod 403 fixedly installed at the end of the pad 402; and a fourth return spring 404 fixedly installed between the connecting rod 403 and the mounting shell 401, which is sleeved on the connecting rod. On 403; a limiting arm 405 rotatably mounted on the mounting housing 401, which is used to limit the connector 002; a rack 406 fixedly mounted on the pad 402 and embedded in the pad 402; a spur gear 407 rotatably mounted in the mounting housing 401, which meshes with the rack 406; a sandwich gear 408 rotatably mounted in the mounting housing 401, which is coaxially fixed with the limiting arm 405, and the thickness of the sandwich layer inside is the same as the thickness of the rack 406. The thickness of the spur gear 407 is the same as the overall thickness of the sandwich gear 408, so that the sandwich gear 408 can mesh with the spur gear 407 without meshing with the rack 406.

[0035] Combination Figure 9As shown, the device also includes a control column 409 fixedly installed on the base 101. With the rotation direction of the transfer disk 107 as the reference, the control column 409 is located downstream of the recording device 108. The rotation of the transfer disk 107 controls the material discharge chute 201 to pass through the recording device 108 and the control column 409 in sequence. When the material discharge chute 201 passes the control column 409, the control column 409 will contact the limiting arm 405 and control the limiting arm 405 to rotate under the action of relative displacement.

[0036] Combination Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, a slot 501 is provided on the limiting arm 405; the device also includes: a locking mechanism disposed on the limiting mechanism for locking it, which includes: a locking frame 502 slidably mounted on the mounting housing 401, which makes vertical displacement, and the locking frame 502 will insert into the slot 501 to lock the angular position of the limiting arm 405; a fifth return spring 503 fixedly mounted between the locking frame 502 and the mounting housing 401, which is sleeved on the sliding shaft of the locking frame 502; and an unlocking plate 504 fixedly mounted on the locking frame 502 to increase the contact area of ​​the locking frame 502.

[0037] Combination Figure 9 As shown, the device also includes an unlocking arm 505 fixedly installed on the base 101. With the rotation direction of the transfer disk 107 as the reference, the unlocking arm 505 is located downstream of the testing device 105. The rotation of the transfer disk 107 controls the material feeding trough 201 to pass through the testing device 105 and the unlocking arm 505 in sequence. When the material feeding trough 201 passes the unlocking arm 505, the unlocking plate 504 will contact the unlocking arm 505 and control the limiting arm 405 to move downward under the action of relative displacement and disengage from the slot 501.

[0038] During the transfer of the material discharge chute 201 from the recording device 108 to the testing device 105, the material discharge chute 201 passes the control column 409. The rotational power of the transfer disk 107 causes the control column 409 to push the limiting arm 405 to rotate, controlling the limiting arm 405 to move to restrict the end of the connecting line 003 connected to the connector 002. At the same time, the rotation of the limiting arm 405 drives the interlocking gear 408 to rotate synchronously, which in turn drives the spur gear 407 to rotate. The rotation of the spur gear 407 drives the rack 406 to move, causing the pad 402 to extend into the connecting line 002. Between points 3, the connecting line 003 is restricted and supported. At this time, the fourth return spring 404 is compressed. That is, the pad 402 and the limiting arm 405 work together to restrict the connecting line 003, which is not yet fixed in position, to ensure that the position of the connector 002 remains unchanged so that it can be accurately docked with the female connector 202 later. When the limiting arm 405 is rotated into place by the control column 409, the locking frame 502 moves upward under the action of the fifth return spring 503 and inserts into the slot 501 to lock the limiting arm 405, thereby ensuring the limiting function of the limiting arm 405 and the pad 402.

[0039] Subsequently, the limiting mechanism moves in a locked state along with the feeding trough 201 to below the testing device 105. Since the positions of connector 002 and connecting line 003 are more stable at this time, when the pressing arm 207 presses down on connector 002, connector 002 can more accurately engage with the interface of female connector 202.

[0040] Next, the discharge trough 201 moves downwards towards the adsorption device 104. During this process, the discharge trough 201 passes through the unlocking arm 505. With the help of the rotational power of the transfer plate 107, the unlocking arm 505 presses the unlocking plate 504 downwards, causing the locking frame 502 to disengage from the slot 501. The fifth return spring 503 is compressed, and the limiting arm 405 is unlocked. The fourth return spring 404 is restored, causing the pad 402 to move in the opposite direction to reset and the limiting arm 405 to rotate in the opposite direction to reset, thereby releasing the restriction on the connector 002 and the connecting wire 003, ensuring that the battery 001 can be freely transferred later. After the unlocking plate 504 disengages from the unlocking arm 505, the locking frame 502 abuts against the outside of the limiting arm 405, waiting to cooperate with the slot 501 during the next locking operation.

[0041] The complete process of this equipment is as follows: When the battery 001 to be tested is added to this equipment, firstly, the conveying device 102 continuously conveys the battery 001 to the base 101, and the transfer device 103 and the adsorption device 104 transfer the battery 001 to the discharge trough 201 to complete the automatic feeding; then, the transfer plate 107 rotates intermittently, driving the battery 001 to move. When the discharge trough 201 enters the adjustment station, the adjustment mechanism automatically adjusts the position of the battery 001 to ensure that the connector 002 and the female seat 202 are aligned; at the locking station, the control column 409 and the limiting mechanism work together to limit the connecting line 003 and the connector 002 through the limiting arm 405 and the pad 402, and the locking mechanism completes the mechanical locking. The test device 105 presses down the pressing arm 207 of the test device 105 to precisely connect the stabilized connector 002 and the female connector 202, and make the micro needle 204 conductive with the solder area 005 of the connector 002. At the same time, the test pin 106 contacts the pin point 203 of the female connector 202, thereby achieving stable electrical conduction and ensuring stable performance testing. After the test is completed, the transfer tray 107 continues to rotate to the unlocking station, and the unlocking arm 505 automatically releases the locking state of the restriction mechanism. Finally, the adsorption device 104 transfers the tested battery 001 to the collection area, and the empty discharge tray 201 can start a new round of testing cycle.
