Description

Technical Field

[0001] The invention belongs to the technical field of automated operations, and in particular relates to a terminal fastening device for a long cable of a large battery. Background Art

[0002] Batteries have been widely used in various fields of people's lives due to their excellent performance. Therefore, people's requirements for battery performance are getting higher and higher.

[0003] In order to ensure the quality of the battery, the battery needs to be tested during the battery production process. Most of the existing testing methods are to load the battery into the test carrier, and then snap the battery terminal and the test head on the test carrier to complete the test of relevant performance. In actual research, it is found that this method is only applicable to the automated snap-in test operation of conventional size structure batteries. For some large batteries with long cables, such as large batteries used in laptops, due to their large size and long cables, if they are pre-loaded into the test carrier, the battery and the long cables on the battery will be limited by the positioning function of the test carrier. When snapping the test head with the terminal on the battery, there are large space limitations, and it is difficult to achieve automated snap-in operation. In addition, after the terminal is positioned, due to the lack of floating space, the terminal is also easily damaged during snapping. Therefore, the terminal snap-in operation of such large battery long cables is basically performed manually in the existing technology, and the manual snap-in operation has the problems of inaccurate snap-in and poor operation efficiency.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of them.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See also Figure 1 to Figure 4 A terminal fastening device for a large battery with a long cable is suitable for automatically fastening the terminals of a large battery with a long cable, specifically, fastening the terminals on the battery with a test head.

[0044] Figure 4 , which is a schematic diagram of a large battery with a long cable applicable to the present embodiment, the battery 700 has a long cable 710, one end of the long cable 710 is connected to the battery body, and the other end of the long cable 710 is provided with a terminal 720 to be tested for fastening. More specifically, when the battery body is placed in a horizontal state, the terminal 720 is in a vertical state.

[0045] The fastening device includes a turntable mechanism 100, a first loading mechanism (not shown in the figure) for loading a test head, a second loading mechanism 200 for loading a battery, a photographing mechanism 300 for obtaining the positions of the test head and the terminals on the battery, a fastening mechanism 400 for fastening the test head and the terminals on the battery together, and a first unloading mechanism 500 for unloading the fastened test head and the battery together.

[0046] In this embodiment, the test head and the battery are first loaded onto the turntable mechanism 100 in sequence, and then the terminal is automatically fastened with the cooperation of the photographing mechanism 300 and the fastening mechanism 400, and finally the fastened test head and the battery are transported and unloaded together through the first unloading mechanism 500.

[0047] The first feeding mechanism, the second feeding mechanism 200 , the locking mechanism 400 and the first unloading mechanism 500 are sequentially arranged around the rotation direction of the turntable mechanism 100 , and the photographing mechanism 300 is arranged between the turntable mechanism 100 and the locking mechanism 400 .

[0048] It is understandable that after each rotation of the turntable mechanism 100, the first loading mechanism, the second loading mechanism 200, the locking mechanism 400 and the first unloading mechanism 500 can be operated synchronously to achieve automatic rotation and transmission while improving the overall operating efficiency.

[0049] Positions on the turntable mechanism 100 corresponding to the first loading mechanism, the second loading mechanism 200, the snap-fitting mechanism 400 and the first unloading mechanism 500 are all provided with positioning mechanisms 600, and the positioning mechanism 600 includes a positioning platform 610 and a terminal positioning module 620 located on one side of the positioning platform 610, the positioning platform 610 is used to carry the test head and the battery, and the terminal positioning module 620 is used to position the terminals on the battery.

[0050] That is, in this embodiment, a total of four workstations are formed on the turntable mechanism 100, and a positioning mechanism 600 is provided at each workstation. With each rotation of the turntable mechanism 100, each positioning mechanism 600 can correspond to the first loading mechanism, the second loading mechanism 200, the snap-fitting mechanism 400 and the first unloading mechanism 500 respectively.

[0051] In the initial operation stage, the test head is first loaded and transported to the corresponding positioning platform 610 through the first loading mechanism. Subsequently, under one rotation of the turntable mechanism 100, the second loading mechanism 200 transports the battery loading to the positioning platform 610. Then, the terminal positioning module 620 located on one side of the positioning platform 610 positions the battery terminals. When the positioning platform 610 is rotated to the corresponding position of the snapping mechanism 400 under another rotation of the turntable mechanism 100, the snapping mechanism 400 grabs the test head on the positioning platform 610. Subsequently, after obtaining the position information of the test head and the battery terminals through the photographing mechanism 300, the snapping mechanism 400 adjusts the position of the test head to correspond to the position of the battery terminals according to the position information of the test head and the battery terminals obtained by the photographing mechanism 300, and then snaps the test head onto the terminals. Finally, under another rotation of the turntable mechanism 100, the snapped test head and the battery are unloaded and transported under the action of the first unloading mechanism 500.

[0052] It should be noted that since the turntable mechanism 100 is a cyclically rotating operating mode, the positioning mechanisms 600 arranged on the turntable mechanism 100 will move to different operating mechanism positions with each rotation of the turntable mechanism 100. In this embodiment, after the second loading mechanism 200 transports the battery loading to the corresponding positioning platform 610, the terminal positioning module 620 located on one side of the positioning platform 610 will position the terminals on the battery, and the positioning action of the terminal positioning module 620 will be maintained until the fastening mechanism 400 is fastened and before the first unloading mechanism 500 unloads the fastened test head and battery.

[0053] The fastening device provided in this embodiment addresses the problem of difficulty in fastening long cables of large batteries. Instead of the traditional method of pre-positioning the battery in the test carrier, the test head and the battery are sequentially loaded onto the positioning platform 610, which reserves a larger working space for the subsequent operation of the fastening mechanism 400. At the same time, the terminal positioning module 620 is used to position the terminals on the battery to ensure the accuracy of the fastening between the terminals and the test head. It is worth noting that in this embodiment, the terminals on the battery are positioned by the terminal positioning module 620, while the large cables connected to the terminals are not fixed in a unique contoured positioning space. Therefore, during the fastening operation, a certain floating space can be given to the terminals without damaging the terminals due to excessive fastening. In addition, after the operation of the fastening mechanism 400 is completed, the terminal positioning module 620 continues to maintain the positioning function of the terminals, effectively preventing the problem of the test head and the terminals being disengaged.

[0054] In some embodiments, the terminal positioning module 620 includes a first driving component 621, a clamping component 622 and an adsorption component 623. The clamping component 622 and the adsorption component 623 are both connected to the driving end of the first driving component 621. The first driving component 621 drives the clamping component 622 and the adsorption component 623 to move toward the terminal on the battery. The clamping component 622 and the adsorption component 623 play a certain limiting role on the terminal on the battery, and the adsorption component 623 can also play a supporting role during the terminal fastening process to ensure the fastening accuracy.

[0055] Furthermore, the clamping assembly 622 includes a three-jaw cylinder 6221 and three clamping jaws 6222 connected to the driving end of the three-jaw cylinder 6221. The adsorption assembly 623 is located between the three clamping jaws 6222, so that the outer edge of the terminal is restricted between the three clamping jaws 6222, and the side of the terminal opposite to the test head can play a certain supporting role through the adsorption assembly 623, which is convenient for the snap-fit ​​operation.

[0056] It can be seen from the above content that the terminal is arranged at one end of the long cable, and the terminal is in a vertical state relative to the battery body placed in a horizontal state. Here, a three-claw cylinder 6221 is used to drive three clamps 6222 to limit the outer edge of the terminal. Specifically, the three clamps 6222 respectively limit the upper edge, left edge and right edge of the terminal. The adsorption component 623 adopts a vacuum extraction method to adsorb the side of the terminal opposite to the test head. When the test head and the terminal are buckled, it can support the terminal to cooperate with the buckling mechanism 400 to achieve precise buckling operation.

[0057] In some embodiments, the positioning mechanism 600 also includes a pressing module 630 located on one side of the positioning platform 610, and the pressing module 630 is used to press the test head after it is engaged with the upper terminal of the battery to prevent the test head from being disengaged or shifted from the upper terminal of the battery during the rotation of the turntable mechanism 100 after engagement.

[0058] After the snap-fitting mechanism 400 snaps the test head and the terminal together, the test head is located on the positioning platform 610, and the snap-fitting mechanism 400 retreats to its initial state. In order to prevent the test head from being displaced and causing disengagement from the terminal during the process of the turntable mechanism 100 rotating the test head and the battery to the corresponding first unloading mechanism 500, in this embodiment, a pressing module 630 is provided on one side of the positioning platform 610 to press the snapped test head. When the turntable mechanism 100 rotates to rotate the snapped test head to the position corresponding to the first unloading mechanism 500, the pressing module 630 releases the pressing action on the test head to facilitate unloading by the first unloading mechanism 500.

[0059] Embodiment 2:

[0060] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the first material unloading mechanism 500 and the camera mechanism 300 of the present invention, see Figure 5 to Figure 7 .

[0061] See also Figure 5 and Figure 6 The first unloading mechanism 500 includes a manipulator 510 and a first material picking assembly 520 , a second material picking assembly 530 and a material pushing assembly 540 connected to a driving end of the manipulator 510 .

[0062] The first material picking assembly 520 is used for picking up the battery, the second material picking assembly 530 is used for picking up the test head, and the material pushing assembly 540 is used for pushing the battery terminal against the test head. In this embodiment, the battery and the test head are picked up separately, and the battery terminal is pushed against the test head at the same time, which effectively improves the stability of the handling process and prevents the test head from being disengaged from the battery terminal.

[0063] When the first unloading mechanism 500 is performing the material picking operation, the test head and the terminal remain in a buckled state. To avoid disengagement during the material picking process, the pushing assembly pushes the battery upper terminal against the test head to ensure a tight buckled relationship between the test head and the terminal.

[0064] Furthermore, the first material picking component 520 includes a vacuum suction plate for adsorbing the battery, and a plurality of vacuum suction holes are formed on a side of the vacuum suction plate opposite to the battery. The plurality of vacuum suction holes are spaced apart according to the shape of the battery to ensure uniform adsorption effect on various areas of the battery.

[0065] The second material picking component 530 includes an electric cylinder 531 and a clamping arm 532 connected to the driving end of the electric cylinder 531. The electric cylinder 531 drives the clamping arm 532, so that the clamping degree of the clamping arm 532 on the test head can be more accurately controlled to avoid insufficient clamping force or excessive clamping.

[0066] The pushing assembly 540 includes a pushing cylinder 541 and a pushing block 542 connected to the driving end of the pushing cylinder 541. Under the action of the pushing cylinder 541, the pushing block 542 pushes the terminal toward the test head to ensure the tightness of the terminal and the test head to prevent the test head from being disengaged from the terminal on the battery.

[0067] It should be noted that the positional relationship among the first material picking component 520, the second material picking component 530 and the material pushing component 540 is not specifically limited in this embodiment. Instead, corresponding adjustments are made in combination with the battery position, the test head position, and the snap-fit ​​position between the terminal and the test head to ensure that the first material picking component 520, the second material picking component 530 and the material pushing component 540 can all achieve their respective operating functions.

[0068] See also Figure 7 In some embodiments, the photographing mechanism 300 includes a first driving module 310 and a prism camera 320 connected to the driving end of the first driving module 310. The prism camera 320 has two photographing light paths. The first driving module 310 drives the two photographing light paths of the prism camera 320 toward the battery terminals and the test head respectively, so that the position information of the terminals and the test head can be obtained by using one photographing mechanism 300, thereby reducing the number of mechanism settings and reducing equipment costs.

[0069] As can be seen from the foregoing content, the photographing mechanism 300 is located between the turntable mechanism 100 and the snap-fit ​​mechanism 400, and the photographing mechanism 300 is used to obtain the position information of the terminals and the test head. Therefore, in order to avoid the photographing mechanism 300 interfering with the snap-fit ​​operation of the snap-fit ​​mechanism 400, in this embodiment, the first driving module 310 adopts a lifting driving method. When necessary, the first driving module 310 drives the prism camera 320 to rise upward so that the two photographing light paths are respectively directed toward the battery terminals and the test head. After obtaining the position information, the first driving module 310 drives the prism camera 320 to descend downward so that the snap-fit ​​mechanism 400 can snap-fit ​​the terminals on the turntable mechanism 100.

[0070] Embodiment 3:

[0071] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the buckling mechanism 400 of the present invention, see Figure 8-Figure 9 .

[0072] In this embodiment, the snap-fit ​​mechanism 400 includes a grabbing module 410 for grabbing the test head and a position adjustment module 420 for adjusting the position of the grabbing module 410. The grabbing module 410 is connected to the driving end of the position adjustment module 420. The position of the grabbing module 410 is adjusted by the position adjustment module 420 to accurately snap the test head and the terminal on the battery together, thereby achieving high-precision snap-fitting operation.

[0073] Furthermore, the position adjustment module 420 includes an X-axis driving component 421, a Y-axis driving component 422, a Z-axis driving component 423 and an R-axis driving component 424; the Y-axis driving component 422 is connected to the driving end of the X-axis driving component 421, the Z-axis driving component 423 is connected to the driving end of the Y-axis driving component 422, and the R-axis driving component 424 is connected to the driving end of the Z-axis driving component 423; the grasping module 410 is connected to the driving end of the R-axis driving component 424, so as to realize the position adjustment function of the position adjustment module 420 on the grasping module 410.

[0074] In combination with the terminal position information and test head position information obtained by the photographing mechanism 300, the grasping module 410 adjusts the relative terminal position under the joint action of the X-axis direction driving component 421, the Y-axis direction driving component 422, the Z-axis direction driving component 423 and the R-axis direction driving component 424 to ensure that the test head is accurately buckled with the terminal.

[0075] In some embodiments, the grabbing module 410 includes a grabbing cylinder 411 and a grabbing arm 412 connected to the driving end of the grabbing cylinder 411; a roller 413 is provided on the upper end of the side of the grabbing arm 412 for contacting the test head, and the roller 413 is used to prevent the test head from tilting upward during the snapping process.

[0076] In this embodiment, the grabbing arm 412 grabs the two ends of the test head under the driving action of the grabbing cylinder 411, and then adjusts the position of the test head relative to the terminal under the action of the position adjustment module 420 and buckles the test head and the terminal together. During the specific buckling, the test head is buckled from top to bottom. Therefore, by arranging the roller 413 on the grabbing arm 412, the upper end of the test head is limited to avoid the test head from tilting upward during the buckling process.

[0077] The present invention provides a terminal fastening device for a long cable of a large battery. After loading a test head and a battery onto a turntable mechanism in sequence, position information of the test head and the terminals on the battery is obtained by a photographing mechanism, and the test head and the terminals on the battery are fastened together by the fastening mechanism. The test head and the battery are then unloaded together, thereby realizing the automated fastening operation of the terminals of the long cable of a large battery and effectively improving the accuracy and efficiency of the fastening operation.
