[0038] See also Figure 1 As shown, the embodiment of the present application provides a transfer device 100, which can be used for production transfer of various materials. For ease of understanding, in the embodiment of the present application, the transfer of cylindrical cells 200 in a lithium battery module can be used as an application scenario of the transfer device 100.
[0039] Specifically, the transfer device 100 includes a grabbing module 110, a conveying module 120 and a bracket 130. The grabbing module 110 is used to grab the battery cell 200 to be transferred, the conveying module 120 is used to drive the grabbing module 110 and the grabbed battery cell 200 to move to a designated station, and the bracket 130 is used to provide a mounting carrier for the conveying module 120 to support the conveying module 120 and the grabbing module 110.
[0040] Continue reading Figure 2 and Figure 3 As shown, the grabbing module 110 includes a limit seat 111, a first driving member 112 and a plurality of adsorption members 113. The limit seat 111 is provided with a plurality of through holes and a plurality of limit grooves 1111, and a group of limit grooves 1111 are coaxially arranged with the through holes. Each adsorption member 113 is respectively penetrated through a corresponding through hole to adsorb the battery cell 200 during the downward movement, and to adsorb the battery cell 200 into the limit groove 1111 during the upward movement to maintain the stability of the battery cell 200 during the movement. The first driving member 112 has an output end that can be extended and retracted up and down, and the output end of the first driving member 112 is simultaneously connected to each adsorption member 113 to simultaneously drive each adsorption member 113 to move up and down.
[0041] For example, the number of the adsorbents 113 can be two, three, four, five, six, etc., and correspondingly, the number of through holes and limit slots 1111 is also two, three, four, five, six, etc., so that each adsorbent 113 has a through hole to meet the simultaneous absorption and transportation of multiple battery cells 200. The first driving member 112 can be one of a pneumatic cylinder, a hydraulic cylinder and a linear motor, which can be selected according to actual needs to drive the adsorbent 113 to rise and fall.
[0042] Continue reading Figure 4 , Figure 5 and Figure 6 As shown, specifically, during the operation of the grab module 110, the first driving member 112 drives each adsorption member 113 along the first direction z, so that each adsorption member 113 extends out of the limiting groove 1111 through the through hole until it contacts the battery cell 200 on the work station, thereby sucking the battery cell 200 tightly. Then, the first driving member 112 drives the adsorption member 113 along the first direction z again, so that the adsorption member 113 sucks the battery cell 200 back into the limiting groove 1111. When the battery cell 200 is pressed against the top surface of the limiting groove 1111, the first driving member 112 remains stationary. At this time, the battery cell 200 is clamped by the wall of the limiting groove 1111, which can further improve the stability of the grabbing of the battery cell 200 and ensure that the battery cell 200 moves after being adsorbed by the grab module 110. When the grabbing module 110 clamps the battery cell 200 to reach the set workstation, the first driving member 112 further drives the adsorption member 113 along the first direction z, and the battery cell 200 is restricted by the top surface of the limiting groove 1111 and cannot follow the movement. The adsorption member 113 is separated from the battery cell 200, and the battery cell 200 falls onto the workstation, completing the automatic transfer of the battery cell 200. The overall structure is streamlined, reducing production costs and improving work efficiency.
[0043] It should be noted that the first direction z in the embodiment of the present application refers to the direction of gravity, the limiting groove 1111 is a cylindrical groove structure and is coaxially arranged with the through hole, and the inner diameter of the limiting groove 1111 is larger than the through hole. In this way, when the adsorbent 113 drives the battery cell 200 to rise, the battery cell 200 cannot follow the adsorbent 113 into the through hole. And when the battery cell 200 is separated from the adsorbent 113, under the action of gravity, the battery cell 200 automatically falls on the work station.
[0044] In some embodiments, the adsorbing member 113 is a magnetic adsorbing member. It is understandable that the pole of the battery cell 200 is a metal terminal and can be adsorbed by the magnet 1132 , so that when the adsorbing member 113 is close to the battery cell 200 , the battery cell 200 is adsorbed on the adsorbing member 113 .
[0045] Continue reading Figure 7 As shown, in some embodiments, the adsorption member 113 includes an adsorption column 1131 and a magnet 1132 , one end of the adsorption column 1131 is connected to the output end of the first driving member 112 , and the magnet 1132 is fixed to one end of the adsorption column 1131 away from the first driving member 112 .
[0046] It can be understood that the limit seat 111 is a metal workpiece, and the adsorption column 1131 is the main structure of the adsorption component 113. Therefore, under the condition that the adsorption column 1131 is non-magnetic, the adsorption column 1131 can move up and down in the through hole driven by the first driving component 112, so that the magnet 1132 is close to or away from the battery cell 200, thereby realizing the absorption and detachment of the battery cell 200.
[0047] In some embodiments, the grabbing module 110 also includes a mounting seat 115, a second driving member 116 and a guide seat 117, one side of the mounting seat 115 is connected to the conveying module 120, the second driving member 116 is fixed to the mounting seat 115 and the output end is connected to the guide seat 117, and the first driving member 112 is installed on the guide seat 117.
[0048] Specifically, the mounting seat 115 is a metal welding workpiece, one side of which is mounted on the conveying module 120 to move with the conveying module 120. The second driving member 116 is mounted on the mounting seat 115 and has an output end that is telescopic along the first direction z, the guide seat 117 is mounted on the output end of the second driving member 116, and the first driving member 112 is mounted on the guide seat 117, so that the first driving member 112 and the guide seat 117 can move along the first direction z under the action of the second driving member 116, and further adjust the height position of the adsorbent 113 in the first direction z, so as to facilitate the adsorbent 113 to absorb the battery cell 200.
[0049] Exemplarily, the first driving member 112 may also be one of a pneumatic cylinder, a hydraulic cylinder and a linear motor, and the specific selection may be made according to actual needs, as long as it can drive the guide seat 117 to rise and fall.
[0050] In some embodiments, the grabbing module 110 further includes a connecting plate 114 , one side of which is connected to the first driving member 112 , and each adsorption member 113 and the limiting seat 111 are installed on a side of the connecting plate 114 facing away from the first driving member.
[0051] Specifically, the connecting plate 114 is a long strip structure, and the middle part of one side thereof is fixedly connected to the output end of the first driving member 112. The connecting plate 114 is located vertically above the limiting seat 111. The adsorbents 113 are equidistantly distributed on the side of the connecting plate 114 facing away from the first driving member 112, and one end of the adsorbent 113 is fixedly connected to the connecting plate 114, and the other end is passed through the through hole of the limiting seat 111. In this way, under the drive of the first driving member 112, the connecting plate 114 moves along the first direction z, and at the same time drives the adsorbents 113 to move synchronously in the first direction z.
[0052] In some embodiments, the grabbing module 110 further includes at least one guide rod 118 . Each guide rod 118 movably passes through the guide seat 117 and one end of each guide rod 118 is fixed to the connecting plate 114 .
[0053] Specifically, a plurality of holes are provided on the guide seat 117 and penetrate the guide seat 117, which are fixed to the connecting plate 114 through a guide rod 118 and movably penetrated through the guide seat 117, so that the connecting plate 114 can move relative to the guide seat 117. Under the restriction of the guide rod 118, the connecting plate 114 can only move along the first direction z following the first driving member 112, thereby avoiding the displacement of the adsorption member 113 during the movement and ensuring the accuracy of the adsorption of the battery cell 200.
[0054] In this specific embodiment, two guide rods 118 are provided, and the two guide rods 118 are relatively arranged at the two ends of the connecting plate 114. Through the two symmetrically arranged guide rods 118, the two ends of the connecting plate 114 maintain the same connection strength, ensure the stability of the two ends, and meet the stable lifting and lowering movement of each adsorption member 113.
[0055] Continue reading Figure 8 As shown, in some embodiments, the conveying module 120 may be a linear guide rail, which includes a driving cylinder and a slider, and the slider can move along the second direction x under the drive of the driving cylinder, and the grabbing module 110 is installed on the slider so that it can reciprocate along the second direction x under the drive of the conveying module 120.
[0056] It should be noted that the second direction x in the embodiment of the present application refers to the conveying direction of the conveying module 120, and the second direction x is perpendicular to the first direction z, so that the conveying module 120 drives the grabbing module 110 to move horizontally, and the adsorbent 113 can move up and down under the drive of the second driving member 116, so as to realize the multi-directional movement of the adsorbent 113, realize the position adjustment of the adsorbent 113 and the transportation process of the battery cell 200. Of course, in other embodiments, the conveying module 120 can also be a chain transmission structure or a screw transmission mechanism, etc., which can meet the horizontal movement of the grabbing module 110.
[0057] Continue reading Fig. 9 As shown, in some embodiments, the transfer device 100 further includes a bracket 130 , and the conveying module 120 is installed on the bracket 130 .
[0058] Specifically, the bracket 130 includes two supporting columns 131 arranged opposite to each other and a crossbeam 132 connected to the top ends of the two supporting columns 131. The supporting columns 131 are arranged in parallel along the first direction z, and the bottom ends are installed on a workbench or the ground to support the conveying module 120. The crossbeam 132 is arranged in parallel along the second direction x, and the two ends are respectively fixed to the two supporting columns 131. The conveying module 120 is fixed on the crossbeam 132 to ensure the stable installation of the conveying module 120 and provide a telescopic movement space for the second driving member 116.
[0059] An embodiment of the present application further provides a battery production device, comprising the transfer device 100 in any of the above embodiments.
[0060] This embodiment has the transfer device 100 in any of the above embodiments, and therefore has all the beneficial effects of the transfer device 100 in any of the above embodiments, which will not be described in detail here.
[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
