[0020] For the cell product multi-station crimping jig provided by the embodiment of the application, when the plurality of cell products are subjected to crimping test, firstly, the plurality of cell products are placed on the carrier board at intervals.

DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0035] Figure 1 is a first view of a multi-station crimping jig for a cell product provided by an embodiment of the present application, Figure 2 is a second view of a multi-station crimping jig for a cell product provided by an embodiment of the present application, in combination with Figure 1 and Figure 2 , the crimping jig comprises a support assembly 1, a driving assembly 2 and a plurality of crimping assemblies 3.

[0036] The support assembly 1 comprises a carrier plate 11 and a support seat 12 (see Figure 3 and Figure 4 ), and the support seat 12 is located on the carrier plate 11.

[0037] Figure 5is a partial schematic view of a driving member provided by the embodiment of the present application, as shown in Figure 5 The driving assembly 2 comprises a driving member 21, a fixed rod 22 and a plurality of levers 23 (see Figure 6 and Figure 7 ), the driving member 21 is hinged on the carrier plate 11, the output shaft of the driving member 21 is in driving connection with the fixed rod 22 to drive the fixed rod 22 to lift and drop, each fixed rod 22 is provided with a plurality of driving shafts 221 arranged detachably, the plurality of driving shafts 221 are arranged at intervals, the middle part of each lever 23 is hinged on the carrier plate 11, and one end of each lever 23 is hinged with the fixed rod 22 through the corresponding driving shaft 221.

[0038] Each compression assembly 3 comprises a compression head 31 and an FPC 32, each compression head 31 is slidably arranged on the support seat 12, and the sliding direction of each compression head 31 is perpendicular to the carrier plate 11, a compression spring 33 is clamped between each compression head 31 and the top of the support seat 12, the FPC 32 is located on the bottom of the corresponding compression head 31, and the other end of each lever 23 is located below and abuts against the corresponding compression head 31.

[0039] For the multi-station compression jig for cell products provided by the embodiment of the present application, when the plurality of cell products 100 are subjected to compression test, first, the plurality of cell products 100 are placed at intervals on the carrier plate 11. Then, the output shaft is driven to move upward by the driving member 21, thereby driving the fixed rod 22 and the driving shaft 221 to move upward, so that the right end of each lever 23 moves upward and the left end moves downward, and the left end of each lever 23 releases the abutting effect on the corresponding compression head 31. At this time, the compression head 31 is driven to move downward by the compression spring 33, thereby realizing automatic compression of the corresponding cell product 100. Since the compression spring 33 provides elastic force, the downward pressure on the compression head 31 and the FPC 32 gradually decreases during the downward movement of the compression head 31, and has a certain buffering effect on the compression head 31 and the FPC 32, thereby avoiding the Mark point of the cell product 100 from being damaged.

[0040] Similarly, when the next batch of cell products 100 needs to be replaced after the test is completed, the output shaft is driven to move downward by the driving member 21, thereby driving the fixed rod 22 and the driving shaft 221 to move downward, so that the right end of each lever 23 moves downward and the left end moves upward, and the left end of each lever 23 will overcome the elastic force of the compression spring 33 to push the compression head 31 upward, at this time, the plurality of cell products 100 subjected to test are removed, and the plurality of cell products 100 to be tested are placed, and the above steps are repeated.

[0041] Further, when the FPC needs to be replaced or the driving member 21 is damaged or fails, the driving shaft 221 is disassembled, the fixed rod 22 loses linkage with the corresponding lever 23, the lever 23 is manually pressed to make the pressing head 31 lift, the lever 23 is small in size and is not easy to interfere, so that the FPC 32 can be conveniently replaced. At this time, the lever 23 can be manually controlled by manually rotating the right end of the lever 23, so as to realize manual crimping and ensure the test progress.

[0042] That is, the multi-station crimping jig for the cell product provided by the embodiment of the application not only can avoid the Mark point of the cell product 100 from being damaged, but also can realize manual crimping when the driving member 21 fails or is damaged, and can conveniently replace the FPC 32, so as to ensure the test progress.

[0043] Exemplarily, the driving member 21 can be a linear motor or a pneumatic cylinder. The driving member 21 is hingedly connected to the seat body 211, and the seat body 211 is located below the carrier plate 11.

[0044] Exemplarily, the pressing head 31 is in a T-shaped structure.

[0045] It is easy to understand that, when the driving member 21 normally works, the driving member 21 is hingedly connected, and the lifting height (oblique lifting) of the driving member 21 in the vertical direction is less than that of the fixed installation, so as to reduce the lifting height of the pressing head 31 in the vertical direction and save space. In addition, based on the principle of the lever 23, the length of the left end of the lever 23 is less than that of the right end of the lever 23, the acting force of the right end of the lever 23 is increased by reducing the force arm, so that the acting force of the lever 23 on the pressing head 31 can be increased, and the action rate can be improved.

[0046] Again referring to Figure 6 and Figure 7 , the driving assembly 2 further comprises a plurality of reset springs 24, and two ends of each reset spring 24 are respectively abutted with the carrier plate 11 and one end of the lever 23.

[0047] In the above embodiment, on the one hand, when the driving member 21 normally works, the reset spring 24 can provide an upward restoring force, so as to cooperate with the driving member 21 to lift the lever 23 and increase the action rate in the crimping process. On the other hand, when the driving member 21 fails or is damaged, the reset spring 24 can also provide an upward restoring force, so as to avoid manually lifting the lever 23 during manual operation, thereby saving manpower.

[0048] It should be noted that the elastic force of the reset spring 24 is greater than that of the pressure spring 33.

[0049] Further, the carrier plate 11 has a plurality of positioning plates 111, each of which has a positioning hole 1111, and the bottom end of each return spring 24 is inserted into the corresponding positioning hole 1111, so that the positioning plate 111 can be used to position and install the return spring 24.

[0050] In this embodiment, the bottom of the pressing head 31 is inserted with a rotating shaft 311, each of which is sleeved with a bearing 312, which is located above the other end of the corresponding lever 23 and abuts against the corresponding lever 23.

[0051] In the above embodiment, the rotation of the bearing 312 on the rotating shaft 311 can make the lever 23 contact the pressing head 31 through the bearing 312 during the pressing process, thereby reducing the friction.

[0052] In addition, the support base 12 has a plurality of sliding modules 122 arranged at intervals, each of which includes a sliding rail 1221 and a sliding block 1222, each of which is located on the support base 12, each of which is in sliding fit with the corresponding sliding rail 1221, and each of which is connected with the corresponding pressing head 31, so that the lifting of the pressing head 31 is realized through the sliding block 1222 module, and the accurate pressing of the pressing head 31 is ensured.

[0053] For example, the carrier plate 11 has a plurality of lever seats 112, each of which is inserted with a lever rotating shaft 1121, and the middle part of each lever 23 is rotatably sleeved on the corresponding lever rotating shaft 1121, and the lever seat 112 serves as the fulcrum of the lever 23 to ensure the stable rotation of the lever 23.

[0054] In this embodiment, a magnet 313 is inserted into each pressing head 31, and the bottom of the pressing head 31 has a clamping plate 314 which is adsorbed with the magnet 313, and the FPC 32 is clamped between the pressing head 31 and the clamping plate 314.

[0055] Again referring to Figure 3 and Figure 4 , the support base 12 has a plurality of limiting screws 121, and the limiting screws 121 penetrate the support base 12, and each limiting screw 121 is located above the corresponding lever 23 to abut against one end of the lever 23.

[0056] In the above embodiment, the limiting screw 121 has a limiting effect on the right end of the lever 23, which can keep the pressing head 31 in a lifted state when replacing the FPC 32, thereby avoiding manual pressing.

[0057] In addition, the top of the support base 12 has a plurality of threaded holes 123, an adjusting screw 124 is inserted into each threaded hole 123, and the top end of each pressure spring 33 is inserted into a corresponding threaded hole 123 and abuts against the corresponding adjusting screw 124.

[0058] In the above embodiment, by screwing the adjusting screw 124, the position of the pressure spring 33 can be adjusted, thereby adjusting the pressure of the pressure spring 33 (the position of the pressing head 31 on the lever 23 is constant), and thereby adjusting the force of the pressure spring 33 on the pressing head 31.

[0059] Illustratively, a top block (not shown in the figure) is inserted into the threaded hole 123, and the top block is located at the bottom end of the adjusting screw 124 and abuts against the top of the pressure spring 33.

[0060] Illustratively, the fixed rod 22 has a plurality of fixed seats 222 arranged at intervals, and each driving shaft 221 is detachably inserted into a corresponding fixed seat 222.

[0061] In the above embodiment, the fixed seat 222 supports the driving shaft 221, facilitating the installation and disassembly of the driving shaft 221.

[0062] Figure 8 is a structural schematic diagram of a carrier plate provided by an embodiment of the present application, as shown in Figure 8 The two side edges of the carrier plate 11 each have a handle 113, facilitating the carrying of the carrier plate 11. In addition, the carrier plate 11 has a quartz glass 114, which serves to support the cell product 100.

[0063] Further, the carrier plate 11 has a base 4 below, and a signal generator is located in the base 4. The signal generator is electrically connected to each FPC 32, thereby transmitting the output electrical signal to the FPC 32, and each cell product 100 can be lit.

[0064] The following briefly describes the process flow of the multi-station crimping jig:

[0065] Step 1: The robot places the pieces, and a plurality of cell products 100 are placed on the carrier plate 11.

[0066] Step 2: The adjusting screw 124 is manually adjusted, the pressure spring 33 is adjusted according to the hardness and thickness of the cell product 100, and the pressing head 31 is at the appropriate pressure.

[0067] Step 3: The driving member 21 is pressed to start the button, the pressing head 31 is pressed down, and the cell product 100 is coincidentally crimped with the FPC 32.

[0068] Step 4: The signal generator transmits an electrical signal, and the cell product 100 is lit through the FPC 32.

[0069] Fifth step: the driving member 21 drives the pressure head 31 to rise, the mechanical arm takes the material, and the test is completed.

[0070] The embodiment of the present application also provides a test device, which comprises a multi-station crimping jig for a cell product as described above.

[0071] Those skilled in the art can understand that the above description is only the preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
