In one embodiment, the movable member 12 is slidably coupled to the fixed member 11, and the movable member 12 is slidably movable relative to the fixed member 11 to effect switching of the pressing station between the pressed state and the released state.

The following technical solution will be described by taking the case where the movable member 12 and the fixed member 11 are disposed up and down, and the pressing of the welding belt is achieved from up and down.

Specifically, the movable member 12 is disposed below the fixed member 11, the pressing station is formed between the fixed member 11 and the movable member 12, the transmission assembly 22 abuts against the bottom surface of the movable member 12, and under the driving of the driving member 21, the movable member 12 is lifted up by the transmission assembly 22, and then the movable member 12 moves upward relative to the fixed member 11, so that the pressing station is in a pressing state, or the transmission assembly 22 is driven to return to act, so that the lifting acting force acting on the movable member 12 is removed, and the pressing station is in a releasing state.

Referring to fig. 1 to 3, the transmission assembly 22 includes a transmission member 221 disposed substantially transversely and a plurality of cam rods 225 disposed substantially vertically at intervals on the transmission member 221, the transmission member 221 is connected to the driving member 21, lower portions of the plurality of cam rods 225 are rotatably connected to the transmission member 221, upper portions of the plurality of cam rods 225 are rotatably connected to the fixed member 11, and upper ends of the plurality of cam rods 225 abut against a bottom surface of the movable member 12; when the first position (peach point position) of the cam portion 227 at the upper end of the cam lever 225 abuts against the movable member 12, the movable member 12 is lifted up and pressed against the fixed member 11, and the pressing station is in a pressed state. When the second position (base circle position) of the cam portion 227 on the upper end of the cam lever 225 abuts against the movable member 12, the movable member 12 is lowered and separated from the fixed member 11, and the pressing station is in a released state.

In this embodiment, the transmission assembly 22 includes a transmission member 221 disposed substantially transversely and a cam rod 225 disposed substantially vertically, the cam portion 227 at the upper end of the cam rod 225 abuts against the movable member 12, and the upper end of the cam rod 225 is rotatably connected to the fixed member 11 and the lower end of the cam rod 225 is rotatably connected to the transmission member 221, so that in the process of driving the transmission member 221 to move substantially transversely by the driving member 21, the upper end of the cam rod 225 is driven to rotate around the fixed member 11, and then power is transmitted to the movable member 12 by the cam portion 227, so as to drive the movable member 12 to move relatively to the fixed member 11.

Referring to fig. 1 to 3, optionally, the transmission member 221 is provided with a first pin 228, and the fixing member 11 is provided with a second pin 114, and the cam lever 225 includes a link portion 226 and a cam portion 227. Wherein, one end of the link portion 226 is provided with a first shaft hole (not shown in the drawing), and the first shaft hole is rotatably connected with the first pin shaft 228; and, the cam part 227 is provided at the other end of the link part 226, the cam part 227 is provided with a second shaft hole 271, the second shaft hole 271 is rotatably connected with the second pin 114, and the cam curved surface of the cam part 227 abuts against one side surface of the movable member 12. Further, the rotational connection of both ends of the cam lever 225 is achieved by the fitting between the first shaft hole and the first pin 228 and the fitting between the second shaft hole 271 and the second pin 114.

It can be understood that the cam portion 227 is integrally formed with the link portion 226, the upper end of the cam rod 225 is connected with the cam portion 227, the cam curved surface is a smooth curved surface, the distance between the cam curved surface and the center of the second shaft hole 271 is unequal, and then in the rotation process of the cam portion 227 around the second pin shaft 114, the distance between the center of the second shaft hole 271 and the abutting position of the movable member 12 can be changed, so that the movable member 12 is pushed to move towards the fixed member 11 or the acting force pushing the movable member 12 is released, and the pressing or releasing of the welding belt is realized at the pressing station.

Illustratively, the cam portion 227 rotates counterclockwise, the cam portion 227 is changed from the second position (the base circle position) to the first position (the peach point position) to the movable member 12, and in this process, the distance between the center of the second shaft hole 271 and the movable member 12 is gradually increased, so that the movable member 12 is driven to rise relative to the fixed member 11, and finally the pressing station is switched from the releasing state to the pressing state; when the cam portion 227 rotates clockwise, the cam portion 227 is changed from the first position abutting against the movable member 12 to the second position abutting against the movable member 12, and in this process, the distance between the center of the second shaft hole 271 and the movable member 12 is gradually reduced, that is, the force of pushing up the movable member 12 is removed, so that the movable member 12 can be driven to descend relative to the fixed member 11, and finally the pressing station is switched from the pressing state to the releasing state.

When the plurality of cam rods 225 are disposed between the movable member 12 and the transmission member 221, the plurality of cam rods 225 can operate simultaneously under the driving of the transmission member 221 to provide a stable pushing effect for the movable member 12. Illustratively, at least two cam rods 225 are provided, the two cam rods 225 are disposed in parallel along the length direction of the movable member 12 at intervals, and the cam portions 227 of the two cam rods 225 are abutted against the bottom surface of the movable member 12.

Referring to fig. 3, the length direction of the cam portion 227 is optionally perpendicular to the extending direction of the link portion 226 to construct a "T" shaped cam rod 225. In this way, when the cam portion 227 contacts the movable element 12, the cam portion 227 has a large contact area with the movable element 12, and the pushing stability against the movable element 12 can be further improved.

In some embodiments, the distance between the center of the first shaft hole and the center of the second shaft hole 271 is a first moment arm, and the distance between the center of the second shaft hole 271 and the position where the cam curved surface abuts the movable member 12 is a second moment arm; the ratio of the first force arm to the second force arm is more than or equal to 3.

In this embodiment, a proportional relationship between the first force arm and the second force arm is set, where the first force arm is a power arm, the second force arm is a resistance arm, and the balanced relationship of power x power arm=resistance x resistance arm indicates that, in the case that the first force arm is at least three times as large as the second force arm, the power arm is far larger than the resistance arm, so the driving member 21 only needs to provide a driving force with resistance not less than one third of that, and the cam portion 227 can be driven to rotate to push the movable member 12 to lift. Thus, the larger driving force can be realized by using the lever principle by using the driving piece 21 with smaller specification, the device structure is small and exquisite, and the larger the driving force provided by the driving piece 21 is, the better the compaction effect can be realized on the workpiece at the compaction station.

The compressing device 100 ensures that the cylinders can select smaller specifications when the same clamping force is applied, and the cylinders are arranged transversely instead of vertically, so that space is saved. If more rows of welding strips are required to be pressed at intervals, the structure is lengthened (namely, the fixed part 11 and the movable part 12 are lengthened) and the number of the cam rods 225 is only increased, so that the requirement can be met.

Referring to fig. 2 and 3, in some embodiments, the transmission member 221 includes a first body 222, a second body 223, and a third body 224 disposed substantially horizontally; the second body 223 is connected to one end of the first body 222, and the other end of the second body 223 is hinged with the output end of the driving member 21; the third main body 224 is connected to the other end of the first main body 222 and is disposed parallel to the second main body 223, the third main body 224 is concavely formed with a avoiding groove 220 for one end of the cam rods 225 to rotate, and the first pin shaft 228 is installed in the avoiding groove 220. Namely, the second body 223, the first body 222, and the third body 224 are disposed in a U-shape in a substantially horizontal direction.

In this embodiment, through the connection relationship among the first main body 222, the second main body 223 and the third main body 224, the third main body 224 can be driven to move simultaneously in the process of driving the second main body 223 by the driving member 21, so as to drive one end of the cam rod 225 connected with the third main body 224 to move, and in the moving process, one end of the cam rod 225 rotates around the first pin shaft 228. Thus, the driving member 21, the transmission member 221 and the movable member 12 can be arranged in parallel, so that the device has a more compact structure and is convenient to assemble and disassemble.

Optionally, the number of the avoidance grooves 220 corresponds to the number of the cam rods 225 one by one, and one end of each cam rod 225 is respectively in rotational connection with a first pin shaft 228 arranged in the corresponding avoidance groove 220. In a specific arrangement, the avoidance groove 220 may be a groove body formed by taking the first pin 228 as a center, and taking the main body of the connecting rod portion 226 on one side of the first pin 228 away from the cam portion 227 as a circle with a radius, where the groove body may prevent the inner side wall of the groove from blocking the rotation of the other end of the cam rod 225. In some embodiments, only one avoidance groove 220 may be provided, and the first pins 228 corresponding to the cam rods 225 are disposed in the avoidance groove 220 at intervals, where the intervals satisfy the rotation of the connected cam rods 225.

In some embodiments, the output end of the driving member 21 is connected with the other end of the second body 223, and the driving member 21 is hinged to the fixing member 11.

It will be appreciated that because the second pin 114 is stationary, the cam lever 225 rotates about the second pin 114 via its cam portion 227. The link portion 226 is hinged to the first pin 228, and the driving member 21 completes driving of the cam lever 225 during driving.

Specifically, the driver 21 is a linear driving cylinder. Referring to fig. 4 (a), when the output end of the linear driving cylinder is in a retracted state, the overall state of the linear driving cylinder is that the output end is obliquely upward, at this time, the end portion of the connecting rod portion 226 connected with the first pin shaft 228 rotates to the lower left, the cam rod 225 is inclined, the second position (base circle position) of the cam portion 227 abuts against the movable member 12, at this time, the movable member 12 is separated from the fixed member 11, and the pressing station is in a loose state; referring to fig. 4 (b), the output end of the linear cylinder gradually extends outwards, so that the second main body 223 is pushed to the right, and then the cam rod 225 is driven to rotate around the first pin shaft 228, the cam rod 225 is vertical, the first position (peach point position) of the cam part 227 abuts against the movable part 12, the movable part 12 is pushed to lift upwards, the movable part is close to and tightly presses the fixed part 11, and the pressing station is in a pressing state. Thus, during the compression of the weld bead, the cam lever 225 rotates, and the driver 21 also rotates. Under ideal conditions, when the compaction station is in a compaction state, the cylinder is driven to rotate to be in a horizontal state by a straight line. At this time, the force is perpendicular to the arm direction, and the driving force is maximum.

Referring to fig. 1, 2 and 5 in combination, fig. 5 is a schematic view of another mating structure of the movable member 12 and the transmission assembly 22 in the pressing device 100 shown in fig. 1.

The driving member 21 for the transmission assembly 22 may be a fixed linear driving cylinder which drives the transmission member 221 in a linear reciprocating motion, in the course of which driving or removal of the movable member 12 towards the fixed member 11 is achieved.

When the solar cell string or the solar cell module is welded, a plurality of welding strips are arranged at intervals. When the fixed part 11 and the movable part 12 are in a long strip shape, the fixed part and the movable part can be integrally pressed, and the position corresponding to the welding strip is the pressing station.

In this embodiment, the first elastic member 410 is disposed at one end of the second pressing block 122 facing the pressing teeth, and when the welding strip between the first pressing block 115 and the second pressing block 122 is pressed, the first elastic member 410 can absorb the processing and mounting errors of the welding strip, so as to ensure that the welding strip is pressed. Preferably, the first elastic member 410 is a flexible elastic member, such as rubber, sponge, etc., so as to ensure that the welding belt is not damaged during the pressing process.

The second elastic member 510 is intended to provide a driving force to drive the movable plate 121 to move away from the fixed plate 111 in the process of changing the pressing station from the pressing state to the releasing state, so as to drive the first press block 115 and the second press block 122 to be separated, thereby facilitating the replacement of the welding strip in the pressing station. The second elastic member 510 is compressed between the fixed plate 111 and the movable plate 121, and provides a force for driving the movable plate 121 away from the fixed plate 111 through the second elastic member 510. It will be appreciated that during the compression of the butt strap, the movable plate 121 first needs to move towards the fixed plate 111 against the elastic force of the second elastic member 510, and during the release of the butt strap, the second elastic member 510 automatically drives the elastic member away from the fixed plate 111. The second elastic member 510 may be a compression spring, rubber, or the like. In some embodiments, the movable plate 121 may be driven away from the fixed plate 111 by using the principle of homopolar repulsion.

To sum up, a specific operation process of the pressing device 100 provided in the technical solution of the present application includes:

the compaction station is changed from the loosening state to the compaction state. The driving member 21 operates to drive the driving member 221 to move, and then drives the cam rod 225 to rotate, at this time, the cam portion 227 in the cam rod 225 rotates counterclockwise, and drives the movable plate 121 abutting against the cam portion 227 to move towards the fixed plate 111 along the guide mechanism 30 against the acting force of the second elastic member 510, so that the second pressing block 122 connected to the movable plate 121 moves synchronously, and passes through the through hole 101 to cooperate with the first pressing block 115 disposed above the fixed plate 111 to clamp the solder strip.

The pressing station is changed from the pressing state to the releasing state, the driving member 21 operates to drive the driving member 221 to move so as to drive the cam rod 225 to rotate, at this time, the cam part 227 in the cam rod 225 rotates clockwise to remove the upward lifting force of the cam rod 225 on the movable plate 121, and in the process, the second elastic member 510 provides driving force to drive the movable plate 121 to move away from the fixed plate 111, so that the second pressing block 122 connected to the movable plate 121 moves synchronously, and the second pressing block 122 is separated from the first pressing block 115 to release the clamped welding strip.

The foregoing description and drawings should not be taken as limiting the scope of the utility model, but rather should be understood to cover all modifications, variations and alternatives falling within the spirit and scope of the utility model as defined by the appended claims.
