[0003] In summary, there are problems of cumbersome test operations and low test efficiency in the battery performance detection devices in the prior art. Summary of the Invention

[0004] The present invention provides a multi-station synchronous automatic lithium battery performance detection device, which can solve the problems of cumbersome test operations and low test efficiency existing in the performance detection devices in the prior art.

[0005] To achieve the above object, according to an embodiment of the first aspect of the present invention, a multi-station synchronous automatic lithium battery performance detection device is proposed, including an outer protective shell, a base fixedly installed on the side of the outer protective shell, and a detection table fixedly installed on the base. A sliding plate is slidably arranged in the detection table.

[0007] It further includes:

[0008] A lithium battery mold is arranged on the sliding plate. A plurality of lithium battery placement slots are arranged on the lithium battery mold, and a protective sleeve is fixedly installed in each lithium battery placement slot.

[0009] A connection component, the connection component includes an adsorption magnetic plate one fixedly installed on the sliding plate, a positioning column arranged on the adsorption magnetic plate one, and an adsorption magnetic plate two fixedly installed at the bottom of the lithium battery mold. A positioning port is arranged on the adsorption magnetic plate two for fitting and installing the positioning column.

[0010] A further improvement lies in that the detection unit includes a battery tester fixed inside the outer housing, a fixing plate fixedly installed at the upper end of the side surface of the outer housing, a lifting cylinder vertically installed on the fixing plate, a rack plate arranged below the fixing plate and connected to the rod body of the lifting cylinder at the top surface, and several pairs of detection probes fixedly installed on the rack plate.

[0011] A further improvement lies in that a clamping groove is arranged on the surface of the sliding plate, and the adsorption magnetic plate I is fixedly installed in the clamping groove.

[0012] A further improvement lies in that fixing knobs are rotatably arranged at the four corners of the surface of the sliding plate.

[0013] A further improvement lies in that bayonets for installing each fixing knob are arranged at the four corners of the lithium battery mold.

[0014] A further improvement lies in that a pair of mounting parts are respectively fixedly installed on the inner walls of both sides of the detection table, ball screws are rotatably arranged in the ports of each pair of mounting parts, and sleeves are fixedly installed on both sides of the bottom surface of the sliding plate, and each sleeve is respectively threadedly sleeved on the ball screw.

[0015] A further improvement lies in that a DC servo motor is fixedly installed on the side surface of each mounting part, and the main shaft of each DC servo motor is connected to the ball screw.

[0016] A further improvement lies in that a prompting component is further included, and the prompting component includes an adjusting prompt board arranged in the port of the detection table and a pair of elastic touch switches fixedly installed on the side of the adjusting prompt board away from the outer housing.

[0017] A further improvement lies in that an adjusting seat is fixedly installed on the side of the outer housing facing the adjusting prompt board, an adjusting groove is arranged on the side of the adjusting seat located on the outer housing, and a pair of micro cylinders are fixedly installed in the middle of the adjusting groove.

[0018] A further improvement lies in that a U-shaped linkage rod is fixedly installed at the rod body end of the micro cylinder, and the rod body of the U-shaped linkage rod passes through the adjusting seat and is connected to the side surface of the adjusting prompt board.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) In the present invention, the lithium battery mold is placed in the clamping groove of the slide plate. At this time, the adsorption magnetic plate two adheres to the adsorption magnetic plate one, and the positioning posts on the adsorption magnetic plate one are accurately inserted into the positioning holes of the adsorption magnetic plate two, thus realizing the rapid assembly of the lithium battery mold. In addition, by rotating the fixing knobs at the four corners of the slide plate, the sides of the fixing knobs are clamped into the clamping holes at the four corners of the lithium battery mold, further strengthening the lithium battery mold and preventing it from shaking due to vibration. One of the major advantages of this design is that the lithium battery mold is provided with a number of lithium battery placement slots, which can place multiple lithium batteries simultaneously, eliminating the need to frequently replace the entire detection device. Moreover, the lithium battery mold can be conveniently disassembled and assembled, greatly simplifying the operation process.

[0021] (2) During the testing process of the present invention, first, according to the specifications of the lithium battery to be tested, the rod bodies of a pair of micro cylinders are extended to drive the U-shaped linkage rod to adjust the position of the adjustment prompt board until it reaches the appropriate position. Subsequently, a pair of DC servo motors are started synchronously, and the motor spindles respectively drive the ball screws to rotate synchronously. With the help of the bottom sleeve, the slide plate slides in the detection table. When the slide plate contacts the elastic touch switch on the side of the adjustment prompt board, the elastic touch switch sends an electrical signal to the detection unit. At this time, the lifting cylinder in the detection unit drives the frame plate and the detection probe, so that the detection probe contacts the positive and negative electrode posts of each lithium battery, and the battery tester immediately synchronously collects the data of each lithium battery. This process effectively shortens the detection time, reduces the labor cost, and significantly improves the efficiency of batch detection of lithium batteries. Description of the Drawings

[0034] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0035] As Figures 1 to 5 shown, a multi-station synchronous automatic lithium battery packaging performance detection device includes an outer housing 2, a base 3 fixedly installed on the side of the outer housing 2, and a detection table 31 fixedly installed on the base 3. A slide plate 32 is slidably arranged in the detection table 31;

[0036] Detection unit 1, used for lithium battery performance detection;

[0037] Specifically, the detection unit 1 includes a battery tester fixed in the outer housing 2, a fixing plate 12 fixedly installed on the upper end of the side of the outer housing 2, a lifting cylinder 13 vertically installed on the fixing plate 12, a frame plate 11 arranged below the fixing plate 12 and connected to the rod body of the lifting cylinder 13 at the top, and several pairs of detection probes 14 fixedly installed on the frame plate 11;

[0038] It should be noted that this part of the detection unit 1 is prior art. Before implementation, each component is assembled and debugged for use. This embodiment is implemented based on this technology;

[0039] The lithium battery mold 4 is arranged on the slide plate 32. The lithium battery mold 4 is provided with a plurality of lithium battery placement slots 41, and a protective sleeve 42 is fixedly installed in each lithium battery placement slot 41;

[0040] Specifically, a pair of mounting members 33 are fixedly installed on the inner walls on both sides of the detection table 31. A ball screw 34 is rotatably arranged in the port of each pair of mounting members 33. Sleeve barrels 321 are fixedly installed on both sides of the bottom surface of the sliding plate 32. Each sleeve barrel 321 is respectively sleeved on the ball screw 34 in a threaded manner. A DC servo motor 35 is fixedly installed on the side surface of each mounting member 33. The main shaft of each DC servo motor 35 is connected to the ball screw 34. By synchronously starting a pair of DC servo motors 35, the main shafts of the motors respectively drive the ball screws 34 to rotate synchronously. With the action of the bottom sleeve barrels 321, the sliding plate 32 slides in the detection table 31. The lifting cylinder 13 drives the frame plate 11 and the detection probe 14, so that the detection probe 14 contacts the positive and negative electrode posts of each lithium battery. The battery tester immediately synchronously collects the data of each lithium battery. This process effectively shortens the detection time, reduces the labor cost, and significantly improves the efficiency of batch detection of lithium batteries;

[0041] As Figure 2 and Figure 4 shown, in this embodiment, another implementation solution is also provided, which is specifically as follows:

[0042] It also further includes a connection component 5. The connection component 5 includes an adsorption magnetic plate one 51 fixedly installed on the sliding plate 32, a positioning column 52 arranged on the adsorption magnetic plate one 51, and an adsorption magnetic plate two 54 fixedly installed at the bottom of the lithium battery mold 4. A positioning port 53 is installed on the adsorption magnetic plate two 54 to cooperate with the positioning column 52. First, the tester selects a lithium battery mold 4 adapted to the lithium battery to be tested according to its specifications and places it in the clamping groove 301 of the sliding plate 32. At this time, the adsorption magnetic plate two 54 adheres to the adsorption magnetic plate one 51, and the positioning column 52 on the adsorption magnetic plate one 51 is accurately inserted into the positioning port 53 on the adsorption magnetic plate two 54, thereby realizing the rapid assembly of the lithium battery mold 4. In addition, by rotating the fixing knobs 55 at the four corners of the sliding plate 32, the sides thereof are inserted into the clamping ports 401 at the four corners of the lithium battery mold 4 to further reinforce the lithium battery mold 4 and prevent it from shaking due to vibration;

[0043] As a preferred implementation solution, a clamping groove 301 is arranged on the surface of the sliding plate 32. The adsorption magnetic plate one 51 is fixedly installed in the clamping groove 301. Fixing knobs 55 are rotatably arranged at the four corners of the surface of the sliding plate 32. Clamping ports 401 for installing each fixing knob 55 are opened at the four corners of the lithium battery mold 4. After the lithium battery mold 4 is initially fixed, by rotating the fixing knobs 55 at the four corners of the sliding plate 32, the sides thereof are inserted into the clamping ports 401 at the four corners of the lithium battery mold 4 to further reinforce the lithium battery mold 4 and prevent it from shaking due to vibration;

[0044] As Figure 5 shown, in this embodiment, another implementation solution is also provided, which is specifically as follows:

[0045] It also further includes a prompting component 6. The prompting component 6 includes an adjusting prompt board 61 arranged inside the port of the detection table 31 and a pair of elastic touch switches 62 fixedly installed on the side of the adjusting prompt board 61 away from the outer casing 2. On the side of the outer casing 2 facing the adjusting prompt board 61, an adjusting seat 63 is fixedly installed. An adjusting groove 601 is formed on one side of the adjusting seat 63 located on the outer casing 2. In the middle of the adjusting groove 601, a pair of micro-cylinders 602 are fixedly installed. At the rod end of the micro-cylinder 602, a U-shaped linkage rod 603 is fixedly installed. The rod of the U-shaped linkage rod 603 passes through the adjusting seat 63 and is connected to the side of the adjusting prompt board 61. During installation and use, by using the elongation of the rods of the pair of micro-cylinders 602 to drive the U-shaped linkage rod 603, the position of the adjusting prompt board 61 is adjusted until it reaches a suitable position. When the sliding plate 32 contacts the elastic touch switch 62 on the side of the adjusting prompt board 61, the elastic touch switch 62 sends an electrical signal to the detection unit 1. At this time, the lifting cylinder 13 in the detection unit 1 drives the frame plate 11 and the detection probe 14, so that the detection probe 14 contacts the positive and negative electrode posts of each lithium battery, and the battery tester immediately synchronously collects the data of each lithium battery;

[0046] It should be noted that both the micro-cylinder 602 and the elastic touch switch 62 are prior arts. Before implementation, an external PLC programmable controller is configured to control the micro-cylinder 602 and the elastic touch switch 62. The elastic touch switch 62 can be a mechanical elastic touch switch 62.

[0047] As Figures 1 to 5 shown, in this embodiment, it should also be noted that the actual sizes and shapes of the components in the application document are selected and installed before implementation according to the actual on-site requirements. In addition, it should be noted that this application document only improves the disadvantages of the existing packaging performance detection device, such as cumbersome test operations and low test efficiency, and does not involve other aspects. The working principle of the multi-station synchronous automatic lithium battery packaging performance detection device is introduced as follows:

[0048] When the lithium battery test is carried out according to the solution of the present invention, the tester first selects a lithium battery mold 4 adapted to the lithium battery to be tested according to its specifications and places it in the clamping groove 301 of the slide plate 32. At this time, the second adsorption magnetic plate 54 adheres to the first adsorption magnetic plate 51, and the positioning column 52 on the first adsorption magnetic plate 51 is accurately inserted into the positioning port 53 of the second adsorption magnetic plate 54, thus realizing the rapid assembly of the lithium battery mold 4. In addition, by rotating the fixing knobs 55 at the four corners of the slide plate 32, the side surfaces thereof are clamped into the clamping ports 401 at the four corners of the lithium battery mold 4 to further reinforce the lithium battery mold 4 and prevent it from shaking due to vibration. One great advantage of this design is that a plurality of lithium battery placement grooves 41 are provided on the lithium battery mold 4, which can place multiple lithium batteries at the same time, eliminating the need to frequently replace the entire detection device. Moreover, the lithium battery mold 4 can be conveniently disassembled and assembled, greatly simplifying the operation process.

[0049] During the test, first, according to the specifications of the lithium battery to be tested, the rod bodies of a pair of micro-cylinders 602 are extended to drive the U-shaped linkage rod 603 to adjust the position of the adjustment prompt board 61 until it reaches the appropriate position. Subsequently, a pair of DC servo motors 35 are synchronously started, and the motor spindles respectively drive the ball screws 34 to rotate synchronously. With the help of the bottom sleeve 321, the slide plate 32 slides in the detection table 31. When the slide plate 32 contacts the elastic touch switch 62 on the side of the adjustment prompt board 61, the elastic touch switch 62 sends an electrical signal to the detection unit 1. At this time, the lifting cylinder 13 in the detection unit 1 drives the support plate 11 and the detection probe 14, so that the detection probe 14 contacts the positive and negative electrode posts of each lithium battery, and the battery tester immediately synchronously collects the data of each lithium battery. This process effectively shortens the detection time, reduces the labor cost, and significantly improves the efficiency of batch detection of lithium batteries.

[0050] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
