Description

[0001] The present disclosure relates to the technical field of battery powder production, and particularly to a sagger force measuring device and a sagger transportation system. Background Art

[0002] A sagger is a container for holding battery material powder, mainly used in the firing process of lithium battery cathode materials. It can protect the powder from the influence of working conditions such as oxygen blowing, air blowing, and flames in the kiln, and avoid the movement, loss, and pollution of materials.

[0003] Before and after the heating of battery powder production, the transportation line uses a clamping device to clamp and move the sagger, so that the saggers are separated and stacked. Since the clamping force of the clamping device for clamping the sagger cannot be accurately measured and controlled, when the clamping force for clamping the sagger is too large, the sagger will be damaged, and when the clamping force for clamping the sagger is too small, the sagger will fall, resulting in the loss of battery powder in the sagger.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0031] As Figures 1 to 3As shown, it is the sagger force measuring device 10 of an embodiment of the present disclosure, including a sagger assembly 100, a wireless instrument assembly 300, and two force measuring components. The sagger assembly 100 includes a sagger main body 110, a support plate 120, and a mounting cross plate 130. The sagger main body 110 is provided with a receiving cavity 1101. The front and rear ends of the support plate 120 are respectively fixedly connected to two inner walls of the sagger main body 110. The support plate 120 divides the receiving cavity 1101 into a counterweight groove 1102 on the right side of the support plate 120 and a mounting groove 1103 on the left side of the support plate 120. Counterweight blocks can be added into the counterweight groove 1102 to adjust the weight of the sagger main body 110. The front and rear ends of the mounting cross plate 130 are respectively fixedly connected to the inner walls of the sagger main body 110. The mounting cross plate 130 can support different inner walls of the sagger main body 110 and provide a mounting position;

[0032] Further, the wireless instrument assembly 300 is installed on the mounting cross plate 130. The two force measuring components 200 are respectively arranged on the inner walls in the front - rear direction of the sagger main body 110. The force measuring components 200 are used to detect the clamping force of the sagger main body 110. When the force measuring components 200 are stressed, electrical signals are generated. The two force measuring components 200 are both electrically connected to the wireless instrument assembly 300. The wireless instrument assembly 300 can display the clamping force of the sagger main body 110. The wireless instrument assembly 300 receives the electrical signals and outputs the numerical value of the force received.

[0033] In this embodiment, counterweight blocks are placed into the counterweight groove 1102 to balance the test sagger assembly 100. The sagger force measuring device 10 is placed on the clamping device 20 for clamping. The force measuring components 200 can measure the clamping pressure received by the sagger main body 110. The sagger assembly 100 outputs electrical signals and transmits the electrical signals to the wireless instrument assembly 300. The wireless instrument assembly 300 displays the force value received by the sagger main body 110. By continuously adjusting the force on the sagger force measuring device 10 through the clamping device 20 and then testing different - weight sagger force measuring devices 10 with different counterweight blocks, the standard clamping force of saggers with different weights can be obtained. Record the weight of the test sagger force measuring device 10 and the standard clamping force of the clamping assembly. During production, set the corresponding standard clamping force according to the recorded data to clamp and produce saggers.

[0034] The above-mentioned sagger force measuring device 10 weights the test sagger body 110 through the counterweight groove 1102, making the weight of the sagger body equal to that of the saggers in the sagger transportation system. The force measuring component 200 accurately measures the clamping force applied by the clamping device 20 to the sagger body 110, and then the wireless instrument component 300 electrically connected to the force measuring component 200 displays the clamping force in real time, so as to facilitate debugging and determine the standard clamping force of the saggers in the production sagger transportation system, obtain the clamping force that the clamping device in the sagger transportation system should apply to the saggers, make the clamping force appropriate when producing the saggers, avoid the problem of damaging the production saggers caused by excessive clamping force, and at the same time avoid the problem of the production saggers falling caused by too small clamping force, thereby reducing the loss of production saggers and production battery powder materials.

[0035] As Figure 1 shown, in one embodiment, through grooves 1104 are formed on both the front and rear sides of the sagger body 110, and both of the two through grooves 1104 communicate with the installation groove 1103. The lower end of each force measuring component 200 is located in the corresponding through groove 1104. In this embodiment, the force measuring component 200 is located in the through groove 1104, so that the force measuring component 200 has enough space to deform, and the material used for the sagger body 110 is reduced, thereby reducing the cost of the sagger force measuring device 10.

[0036] As Figure 1 and Figure 3 shown, in one embodiment, the force measuring component 200 includes a measuring plate 210, a measuring connecting piece 220 and a resistance strain gauge 230. The upper end of the measuring connecting piece 220 is connected to the inner wall of the sagger body 110, the lower end of the measuring connecting piece 220 extends into the through groove 1104, an installation cavity 2201 is formed at the lower end of the measuring connecting piece 220, the resistance strain gauge 230 is arranged in the installation cavity 2201, the output end of the resistance strain gauge 230 is electrically connected to the wireless instrument component 300, and the measuring plate 210 is fixedly connected to the lower end of the measuring connecting piece 220. In this embodiment, the measuring plate 210 and the measuring connecting piece 220 are made of the same material as the production saggers, making the test results more accurate. When the measuring plate 210 is stressed, one end of the measuring plate 210 connected to the measuring connecting piece 220 deforms, causing the resistance strain gauge 230 in the measuring connecting piece 220 to deform. The resistance strain gauge 230 deforms to generate an electrical signal and transmits it to the wireless instrument component 300. The wireless instrument component 300 can display the force on the sagger in real time, enabling the sagger force measuring device 10 to detect the force value quickly, thus simplifying the debugging process.

[0037] As Figure 1 and Figure 4As shown, in one embodiment, the force measuring assembly 200 further includes a buffer gasket 240 disposed between the measurement connection member 220 and the measurement plate 210. In this embodiment, the buffer gasket 240 alleviates the impact force generated by the collision of the test plate, thereby protecting the resistance strain gauge 230 within the measurement connection member 220, and further extending the service life of the test sagger assembly 100.

[0038] As Figure 3 shown, in one embodiment, the force measuring assembly 200 further includes a fixing member 250. A through hole 2202 is formed at the upper end of the measurement connection member 220, and a connection hole 1105 is formed in the sagger main body 110. The fixing member 250 passes through the through hole 2202. One end of the fixing member 250 abuts against the measurement connection member 220, and the other end of the fixing member 250 is threadedly connected to the connection hole 1105. In this embodiment, the measurement connection member 220 is fixed to the sagger main body 110 by the fixing member 250, so that the measurement connection member 220 and the sagger main body 110 are detachable. When the sagger main body 110 or the resistance strain gauge 230 is damaged, it can be quickly replaced, reducing the time for maintaining the test sagger assembly 100.

[0039] As Figure 2 shown, in one embodiment, the bottom of the sagger main body 110 is provided with two limiting grooves 1106. The limiting grooves 1106 communicate with the accommodation cavity 1101, and each limiting groove 1106 communicates with the corresponding through groove 1104. In this embodiment, after the measurement connection member 220 is deformed by force, it contacts the inner wall of the limiting groove 1106. The bottom of the sagger main body 110 blocks the deformation of the measurement connection member 220, preventing the measurement connection member 220 from being bent and damaged due to excessive force, thereby protecting the measurement connection member 220 and further extending the service life of the measurement connection member 220.

[0040] As Figure 1 shown, in one embodiment, the upper end of the support plate 120 is connected to the mounting cross plate 130. In this embodiment, the support plate 120 and the mounting cross plate 130 form an L-shaped structure, such that the two ends of the support plate 120 and the mounting cross plate 130 jointly support the two side walls of the sagger main body 110, thereby increasing the structural strength of the sagger main body 110 and avoiding deformation of the weak part in the middle of the side wall when the sagger main body 110 is stressed.

[0041] As Figure 1As shown, in one embodiment, the number of mounting cross plates 130, support plates 120, and counterweight grooves 1102 is two. The two mounting cross plates 130 extend in the front-rear direction and are arranged in parallel within the sagger body 110. The wireless instrument assembly 300 is mounted above the two mounting cross plates 130, and the two counterweight grooves 1102 are respectively arranged on the left and right sides inside the sagger body 110. In this embodiment, the two side walls of the sagger body 110 are supported by the two mounting cross plates 130, further increasing the structural strength of the sagger body 110. The two counterweight grooves 1102 can be counterweighted simultaneously, making the gravity distribution of the sagger body 110 more uniform, so that the measured value by the force measuring assembly 200 is more accurate.

[0042] As Figure 4 and Figure 5 shown, the present application also provides a sagger transportation system, including a clamping device 20, a lifting table device 30, a transportation line 40, and the sagger force measuring device 10 in any of the above embodiments. The lifting table device 30 is arranged below a part of the transportation line 40. The clamping device 20 includes a first clamping assembly 20a, a second clamping assembly 20b, and a control assembly 20c. The first clamping assembly 20a and the second clamping assembly 20b are respectively arranged on the front and rear sides of the lifting table device 30. The signal output end of the lifting table device 30 is electrically connected to the control assembly 20c, and the control ends of the control assembly 20c are respectively electrically connected to the first clamping assembly 20a and the second clamping assembly 20b.

[0043] In this embodiment, during the test, first configure the sagger force measuring device 10. After counterweighting, the sagger force measuring device 10 is placed on the transportation line 40. The transportation line 40 transports the sagger force measuring device 10 to the lifting table device 30. The lifting table device 30 raises the sagger force measuring device 10. The clamping ends of the first clamping assembly 20a and the second clamping assembly 20b clamp both sides of the sagger force measuring device 10 for testing. The lifting table device 30 descends, and the clamping force of the first clamping assembly 20a and the second clamping assembly 20b is controlled by the control assembly 20c to debug the sagger force measuring device 10. The wireless instrument assembly 300 of the sagger force measuring device 10 can wirelessly transmit the force signal to the wireless receiving end of the control assembly 20c. The obtained standard clamping force can be recorded inside the control assembly 20c. The lifting table device 30 rises to contact the bottom of the sagger force measuring device 10. The first clamping assembly 20a and the second clamping assembly 20b release the sagger force measuring device 10. The lifting table device 30 drives the sagger force measuring device 10 to descend to be flush with the transportation line 40, and the transportation line 40 takes away the sagger force measuring device 10.

[0044] Furthermore, the standard clamping forces of the saggers with different weights are obtained through testing by the sagger force measuring device 10, and the control component 20c can record the standard clamping forces of the saggers with different weights. Thus, during production, the control component 20c controls the first clamping component 20a and the second clamping component 20b to quickly output the corresponding standard clamping forces to clamp the production saggers, avoiding the problem of damaging the production saggers due to excessive clamping force and at the same time avoiding the problem of the production saggers falling due to too small clamping force.

[0045] As Figure 5 shown, in one embodiment, the lifting table device 30 includes a power roller 30a and a lifting platform 30b. The power roller 30a is installed on the lifting platform 30b, and both ends of the power roller 30a are connected to the conveying line 40. In this embodiment, the roller of the power roller 30a can drive the sagger to move, and the lifting platform 30b is used to lift the power roller 30a. The roller on the conveying line 40 drives the sagger to move onto the power roller 30a. By lifting the power roller 30a through the lifting platform 30b to drive the sagger, the height of the sagger is made flush with that of the first clamping component 20a and the second clamping component 20b, facilitating the first clamping component 20a and the second clamping component 20b to clamp the sagger. After the test is completed, the power roller 30a is driven to descend through the lifting platform 30b to drive the sagger to descend, making the power roller 30a flush with the conveying line, so that the roller of the power roller 30a drives the sagger to return to the conveying line 40.

[0046] As Figure 5 shown, in one embodiment, the sagger transportation system further includes a weighing sensor 50. The weighing sensor 50 is arranged at the bottom of the lifting table device 30, and the weighing sensor 50 is electrically connected to the control component 20c. In this embodiment, the weighing sensor 50 is used to measure the weight of the production sagger placed on the lifting table device 30, and the weighing sensor 50 transmits the weight signal of the production to the control component, enabling the control component 20c to include the weight of the sagger as an influencing factor in the calculation process, so that the control component 20c can obtain more accurately the clamping force that should be given to the sagger.

[0047] Furthermore, the sagger transportation system further includes an infrared temperature sensor. The infrared temperature sensor is arranged above the lifting table device 30, and the signal output end of the infrared temperature sensor is electrically connected to the control component 20c. In this embodiment, the infrared temperature sensor can detect in real time the temperature of the material in the production sagger, and the control component 20c collects the data of the material temperature, thus facilitating the monitoring of the temperature change of the material.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] 1. The above-mentioned sagger force measuring device 10 and sagger transportation system use the counterweight groove 1102 to counterweight the test sagger body 110, making the weight of the sagger body equal to the weight of the saggers in the sagger transportation system. Then, the wireless instrument assembly 300 electrically connected to the force measuring component 200 displays the clamping force in real time, thus facilitating the debugging to determine the standard clamping force of the saggers in the production sagger transportation system, obtaining the clamping force that the clamping device in the sagger transportation system should apply to the sagger, ensuring that the clamping force during production is appropriate, avoiding the problem of damaging the production saggers caused by excessive clamping force, and at the same time avoiding the problem of the production saggers falling caused by too small clamping force, thereby reducing the loss of production saggers and production battery powder materials.

[0050] 2. Measure the weight of the production sagger through the weighing sensor 40. The weighing sensor transmits the weight signal to the control component 20c. The control component 20c calculates the clamping force that should be given to the sagger, taking the weight of the sagger into account as an influencing factor during the calculation process, so as to obtain the clamping force that should be given to the sagger more accurately. The control component 20c controls the first clamping component 20a and the second clamping component 20b to quickly output the corresponding standard clamping force to clamp the production sagger, improving the clamping force for saggers of different weights and further improving the accuracy of the clamping force for saggers.

[0051] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
