Fig. 1 and 2 schematically show a receiving and positioning unit 100 of a battery sheet receiving and positioning device. Referring to fig. 1 and 2, the receiving and positioning unit 100 includes a base plate 1 and a positioning mechanism. The positioning mechanism is arranged around the bottom plate and protrudes out of the bottom plate, and a surface facing the preset position at the end part of the positioning mechanism far away from the bottom plate is formed into a guide surface for guiding when the received battery piece deviates from the preset position.

In one embodiment, the positioning mechanism comprises a plurality of positioning pins 3. The bottom panel 1 is formed as a substantially square plate-like structure having two longitudinal edges extending in the longitudinal direction D2 and two transverse edges extending in the transverse direction D1. The base plate 1 is used for supporting the bottom side of the solar cell, and a through hole 2 is formed in the center of the base plate 1, so that the solar cell can cover the base plate 1 when the solar cell is placed at a predetermined position on the base plate 1. Through hole 2's design can be when the solar wafer is placed on bottom plate 1 the balanced bottom plate 1 top side and the pressure differential of bottom side, avoids the solar wafer to take place deformation scheduling problem because of pressure differential.

It should be noted that the "predetermined position" mentioned herein refers to a correct position when the solar cell is placed on the base plate 1, the correct position is preset, and the solar cell can be guided to the predetermined position by providing a positioning mechanism, a swinging mechanism, a detection mechanism, a control mechanism (all will be described in detail later), and the like.

According to one embodiment, the positioning means comprise a plurality of positioning pins 3 arranged around the base plate 1 in relation to the base plate 1, each positioning pin 3 protruding upwards from the base plate 1. The surface at the top of each positioning pin 3 facing the predetermined position is formed as a guide surface, and when the solar cell sheet falls into the receiving and positioning unit 100 from top to bottom slightly away from the predetermined position, the solar cell sheet can contact with the guide surface of the positioning pin 3 to be guided to the predetermined position.

Preferably, the plurality of positioning pins 3 are divided into four groups, and the four groups of positioning pins are respectively arranged along one edge of the bottom plate 1. Specifically, the first group of positioning pins 31 and the second group of positioning pins 32 are arranged along two longitudinal edges of the base plate 1, respectively, and the third group of positioning pins 33 and the fourth group of positioning pins 34 are arranged along two lateral edges of the base plate 1, respectively. In the present embodiment, each set of positioning pins is shown as two, but in other embodiments not shown, each set of positioning pins may be three or more, and preferably each set of positioning pins may be arranged at equal intervals, so that the corresponding positioning pin can guide the solar cell back to the predetermined position no matter which position the solar cell is inclined towards.

More preferably, the distance between the first set of positioning pins 31 and the second set of positioning pins 32 is slightly larger than the transverse dimension of the solar cell, and the distance between the third set of positioning pins 33 and the fourth set of positioning pins 34 is slightly larger than the longitudinal dimension of the solar cell, so that the interference between the positioning pins 3 and the solar cell can be avoided, and the damage rate of the solar cell can be reduced.

Fig. 3A and 3B show a specific example of one positioning pin 3. Referring to fig. 3A and 3B, the positioning pin 3 comprises a first portion 35 and a second portion 36 connected together in a direction perpendicular to the base plate 1, the first portion 35 being formed as a cylinder and being arranged on the base plate 1, the second portion 36 being arranged above the first portion 35 and being formed as a truncated cone coaxial with the first portion 35, which in other embodiments not shown may be a cone.

If the pin 3 is cut off by a plane in which the axis of the pin 3 lies, the profile of the second portion 36 in this section forms an acute angle with the axis. In the present embodiment, the side surface of the truncated cone of the second portion 36 is formed integrally as a guide surface, and of course, a portion of the guide surface that serves as a guide is also a portion that faces a predetermined position. In other embodiments, not shown, the positioning pin may be formed in other shapes, and may have other forms of guide surfaces as long as the guide surface faces the predetermined position and can guide the solar cell sheet to the predetermined position.

In some embodiments, the positioning pin is cut by a plane in which an axis of the positioning pin is located, and an angle between a cross-sectional profile of the positioning pin and the axis is referred to as a positioning pin angle, then preferably, a plurality of positioning pins of one receiving positioning unit may have different positioning pin angles from each other.

Returning to the present embodiment, it is preferable that the material of the second portion 36 is glass or zirconia, or the material of both the first portion 35 and the second portion 36 is glass or zirconia. The arrangement can prevent residues on the positioning pins 3 from being retained on the surface of the silicon wafer, and the residues can be removed from the surface of the silicon wafer in the subsequent purging process, but the residues of the positioning pins made of other materials and contacting with the silicon wafer are difficult to remove.

Referring to fig. 3A and 3B, preferably, height H1 of first portion 35 of locating pin 3 is 2.5mm-3.5mm and diameter d1 of first portion 35 is 17mm-19 mm; the height of the second portion 36 is 7mm-9mm and the diameter d2 of the top surface of the second portion 36 is 9mm-11 mm. The "height" referred to herein refers to a dimension in a direction perpendicular to the base plate 1, such as the direction D3 shown in fig. 3B. Since the second portion 36 and the first portion 35 are coaxial, and the diameter D2 of the second portion 36 is smaller than the diameter D1 of the first portion 35, a space can be provided at the second portion 36 for adjusting the offset error of the battery piece, and the dimension (the dimension in the first direction D1 or the second direction D2) of the battery piece for allowing the offset adjustment of the battery piece, which is provided by each pair of the oppositely arranged positioning pins 3, is approximately 2 (D1-D2)/2, for example, if D1 is 18mm and D2 is 10mm, the dimension for allowing the offset adjustment of the battery piece, which is provided by each pair of the oppositely arranged positioning pins 3, is 8 mm.

More preferably, a pin may be used as the positioning pin 3. In particular, the top of the dowel pin 3 may have a recess 361 to facilitate engagement with an installation tool (e.g., a screwdriver) to secure the dowel pin to the base plate 1. More preferably, at least the surface of the positioning pin 3 facing the predetermined position may be polished, so that the abrasion of the solar cell sheet can be reduced when it is in contact with the solar cell sheet.

Alternatively, the positioning pin 3 may be provided so as to be vertically retractable without using a pin. For example, in a state where the receiving and positioning unit 100 is not used, the positioning pins 3 may be retracted downward such that the top surfaces of the positioning pins 3 and the top surface of the base plate 1 are flush, which can facilitate storage and transportation of the battery piece receiving and positioning device. When the solar cell module is used, particularly during the falling process of the solar cell module, the positioning pins 3 can extend upwards to protrude out of the bottom plate 1, so that the positioning function of the solar cell module is achieved.

The pins of a receiving positioning unit 100 may preferably be made of different materials, such as aluminum alloy, glass, teflon, etc.

In addition to the structure shown in the figures, the battery plate receiving and positioning device preferably may also include some other mechanisms that cooperate with the structure shown in the figures.

For example, the battery piece receiving and positioning device may further include a jacking mechanism for jacking up the bottom plate 1. The jacking mechanism can comprise a cylinder, a motor or a hydraulic instrument and the like. The jacking mechanism is configured to jack the base plate 1 upwards during the process of freely falling the solar cell to the cell receiving and positioning device, that is, the solar cell moves towards the base plate 1 (the movement may be an absolute movement relative to the ground surface) while the base plate 1 moves towards the solar cell (the movement may also be an absolute movement relative to the ground surface). Thus, the free falling distance of the solar cell can be shortened, and the damage which may occur when the solar cell contacts the bottom plate 1 can be reduced.

Preferably, the jacking mechanism is configured to increase and then decrease the upward movement speed of the bottom plate during the process that the solar cell is released until the solar cell is contacted with the bottom plate. The arrangement enables the bottom plate to have a small upward movement speed (which may even be zero) when the solar cell is in contact with the bottom plate, so that the impulse applied to the solar cell in the process that the speed of the solar cell is zero from the free falling speed is small, and the solar cell can be prevented from being damaged.

More intelligently, in order to reduce the free falling distance of the solar cell to a greater extent and avoid overlarge impulse to the solar cell, a control mechanism can be arranged in the cell receiving and positioning device. The control mechanism can adjust the acting force applied to the receiving and positioning unit by the jacking mechanism based on the relative distance and the relative speed of the solar cell and the receiving and positioning unit, so as to adjust the upward movement speed of the receiving and positioning unit. When the relative distance between the solar cell and the receiving and positioning unit is smaller than a preset value, namely the solar cell is immediately contacted with the receiving and positioning unit, the control mechanism enables the receiving and positioning unit to decelerate or stop moving; when the relative speed of the solar cell and the receiving and positioning unit is greater than a preset value, the control mechanism enables the receiving and positioning unit to decelerate or stop moving.

In an embodiment in which the relative speed of the solar cell sheet and the receiving and positioning unit is taken into consideration, the control mechanism is configured to be able to acquire the falling speed of the solar cell sheet and the rising speed of the receiving and positioning unit in real time, calculate the relative speed of the solar cell sheet with respect to the receiving and positioning unit based on the falling speed of the solar cell sheet and the rising speed of the receiving and positioning unit, and control the jacking mechanism to decelerate or stop the movement of the receiving and positioning unit when the relative speed is greater than a predetermined value.

The step of "acquiring" may be implemented by a method of providing a sensor, or may be performed by the control means itself. For example, the receiving positioning device includes a speed sensor, and the control mechanism is configured to acquire a desired speed parameter from the speed sensor; alternatively, the control mechanism is configured to be able to calculate the falling speed of the solar cell in real time based on the time point when the solar cell is released, and calculate the rising speed of the receiving and positioning unit based on the magnitude and time of the force applied to the receiving and positioning unit by the jacking mechanism and a basic parameter preset in the control mechanism, the basic parameter including, for example, the gravity of the receiving and positioning unit.

In an embodiment in which the relative positions of the solar cell pieces and the receiving and positioning unit are taken into consideration, the control mechanism is configured to be able to acquire the position parameters of the solar cell pieces and the position parameters of the receiving and positioning unit in real time, calculate the distance between the receiving and positioning unit and the solar cell pieces based on the acquired position parameters, and control the jacking mechanism to decelerate or stop the movement of the receiving and positioning unit when the distance between the receiving and positioning unit and the solar cell pieces is less than a predetermined value.

The step of "acquiring" may be implemented by a method of providing a sensor, or may be performed by the control means itself. For example, the receiving positioning device includes a position detection device, and the control mechanism is configured to acquire a required speed parameter from the position detection device; or the control mechanism is configured to be capable of calculating the position of the solar cell in real time based on the time point and the position of the released solar cell, and calculating the position of the receiving and positioning unit in real time based on the force magnitude and the time of the jacking mechanism applying force to the receiving and positioning unit and the basic parameters preset in the control mechanism, wherein the basic parameters comprise the gravity of the receiving and positioning unit.

According to the schemes, impulse received by the solar cell piece in the process of enabling the speed to be zero from the free falling speed is small, so that the solar cell piece can be prevented from being damaged, and the free falling distance of the solar cell piece is allowed to be as small as possible on the premise that the solar cell piece is not damaged.

The cell receiving and positioning device may further include a rocking mechanism configured to rock the base plate 1 in a direction parallel to the base plate 1 so that the solar cell is rocked to a predetermined position.

More preferably, the cell receiving and positioning device may further include a control mechanism and a detection mechanism, the detection mechanism is configured to detect the current position of the solar cell on the bottom plate 1 and transmit the detection result to the control mechanism, and the control mechanism is configured to determine whether the current position of the solar cell is a predetermined position (i.e. whether the current position is correctly received by the receiving and positioning unit 100), and send a control signal to the shaking mechanism based on the determination structure so that the shaking mechanism can shake the bottom plate 1 when the solar cell is not accurately located at the predetermined position.

The detection mechanism may also have a number of preferred arrangements. For example, the detecting means comprises a first direction detecting means for detecting the position of the solar cell in a first direction and a second direction detecting means for detecting the position of the solar cell in a second direction, the first direction and the second direction being perpendicular to each other and together defining a plane parallel to the top surface of the base plate 1. In the present embodiment, the first direction may be one of the aforementioned lateral direction D1 and longitudinal direction D2, and the second direction may be the other of the aforementioned lateral direction D1 and longitudinal direction D2.

More preferably, the rocking mechanism is composed of at least two linear rocking mechanisms, each of which is configured to push the receiving positioning unit only in one linear direction, and the directions in which the at least two linear rocking mechanisms can push the receiving positioning unit are different from each other. The arrangement can adopt the propelling device with simple structure to assemble and apply to the battery piece receiving and positioning device, and if the receiving and positioning unit cannot move in a certain direction, the corresponding linear propelling mechanism can be repaired or replaced, thereby reducing the detection and maintenance cost.

On the other hand, the control mechanism is communicatively connected with a release mechanism for releasing the solar battery pieces, and the control mechanism is configured to control the release mechanism to adjust the release positions of the solar battery pieces when the control mechanism judges that the positions where the predetermined number of the solar battery pieces are continuously dropped onto the bottom plate and the predetermined positions are deviated. The feedback adjustment can be realized in the recycling process of the battery piece receiving and positioning device through the arrangement, and the precision of each mechanism can be continuously corrected according to the detection result in actual operation, so that the battery piece receiving and positioning device can be suitable for the actual operation and has better precision in the actual operation.

The above mechanisms can be operated simultaneously. For example, during the process that the solar cell falls into the receiving and positioning unit freely, the jacking mechanism and the shaking mechanism can act simultaneously, so that the free falling distance of the solar cell is shortened, and the solar cell can be shaken to a preset position when the solar cell is not in full contact with the bottom plate.

The cell receiving and positioning device 200 may include a plurality of receiving and positioning units 100 as described above, and the plurality of receiving and positioning units 100 are arranged in a matrix in a direction parallel to the base plate. Although it is schematically shown in fig. 4 that one cell receiving and positioning device 200 may include three rows and four columns of receiving and positioning units 100, in other embodiments, not shown, the cell receiving and positioning device 200 may include a greater or lesser number of rows and a greater or lesser number of columns of receiving and positioning units 100.

To sum up, the utility model provides a be provided with the locating pin that has the spigot surface among the cell piece receiving positioning device, the locating pin sets up around the bottom plate to even make and have certain deviation for its preset position when the contact of solar wafer just with the cell piece receiving positioning device, the spigot surface of locating pin also can lead solar wafer to the correct position. The specific structure and the size of the positioning pin are obtained through multiple experiments, and the positioning pin is very suitable for a conventional solar cell, so that the solar cell can be guided to a preset position efficiently, accurately and nondestructively as much as possible when the solar cell is received.
