[0002] When welding photovoltaic cells, the welding ribbon and the cell need to fit tightly, so a certain pressure needs to be provided to the welding ribbon so that gaps are not easy to appear in the welding process. Generally, the component that provides this pressure is a special welding ribbon pressing tool. During welding, the tool needs to be pressed accurately on the welding ribbon, and each cell requires a tool to provide pressure. In the existing process, the tool is usually grabbed one at a time. Although this action can realize the pick-up and placement of the tool, the action rhythm is slow. In order to improve the discharge rhythm, higher requirements are placed on the accuracy and speed of the pick-up and placement tooling equipment, which invisibly increases the cost of the equipment.

Detailed Embodiments

[0018] To make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] As Figure 1 shown, a handling mechanism applied to the detection and positioning of a pressure - welding belt tooling mainly includes a gantry 11, combined with a cross - translation component 12, a lifting component 13, and a grasping tooling 21. The gantry 11 is the installation and support part. During operation, the gantry 11 is installed across both sides of the tooling pick - up and placement point, and the cross - translation component 12 is installed on the gantry 11, and the cross - translation component 12 is located above the tooling.

[0021] At the same time, the lifting assembly 13 is installed on the transverse moving assembly 12, and the transverse moving assembly 12 controls the horizontal movement of the lifting assembly 13. A longer moving track is provided on the side of the transverse moving assembly 12, so that the lifting assembly can move parallel to the track, and the lifting assembly 13 slides following the sliding connector on the track to achieve position transfer.

[0022] The lifting assembly 13 is used to control the up and down movement of the grabbing fixture 21. In the present application, the lifting assembly is composed of a motor, a driving screw, a guide rail and an adapter assembly. The motor controls the rotation of the driving screw, and the adapter assembly connects the grabbing fixture 21 and the driving screw. The adapter assembly is slidably installed on the vertically arranged guide rail. The adapter assembly realizes sliding work in the vertical direction through the rotation of the screw, thereby driving the movement of the grabbing fixture 21, controlling the up and down movement of the grabbing fixture 21, and realizing the workpiece handling effect.

[0023] During normal operation, after the transport mechanism receives the signal, the transverse movement component 12 drives the longitudinal lifting component 13 and the grabbing tooling 21 to move above the tooling picking point; then the lifting component 13 is activated to lower the grabbing tooling 21 to the picking height and grab the target tooling; then the lifting component 12 is activated to raise the grabbing tooling 21 to a safe height; then the transverse movement component 12 is activated to move the entire structure above the discharge point, then the lifting component 13 is activated to lower the grabbing tooling 21 to the discharge height and put down the tooling; then the lifting component 13 is activated to rise to a safe height and wait for the next signal.

[0024] The grabbing tool 21 includes an electromagnet 31 , which is non-magnetic when powered off, and can absorb the iron part of the tool when powered on.

[0025] The grabbing tooling 21 also includes a connecting frame 22, which is connected to the lifting assembly 13 by bolts. A plurality of spacing frames 25 are installed on the lower end surface of the connecting frame 22, and the spacing frames 25 are all slidably connected to the connecting frame 22. Tracks are provided on both sides of the lower end of the connecting frame 22. The plurality of spacing frames 25 are slidably connected to the tracks through an overhead crane, and are all connected to the same track, so as to facilitate the synchronous transfer between the spacing frames 25.

[0026] The electromagnet 31 is installed below the distance separating frame 25. The electromagnet 31 moves along with the movement of the distance separating frame 25. A connecting block 33 is provided on the distance separating frame 25. A connecting rod is provided at the lower end of the connecting block 33, and the electromagnet 31 is installed at the lower end of the connecting rod. Among them, the electromagnet 31 can slide up and down at the lower end of the connecting rod. A first spring 32 is provided between the electromagnet 31 and the connecting block 33. The first spring 32 is sleeved on the connecting rod. When the distance separating frame 25 controls the electromagnet 31 to move downward to press the tooling, the elastic force of the first spring 32 is compressed to give a reaction force to the electromagnet 31, so as to ensure that the electromagnet 31 fits the workpiece more fully. Especially in this application, the electromagnet 31 is connected to both ends of the distance separating frame 25, and two electromagnets 31 are provided at any one end of the distance separating frame 25. Through the first spring 32, all the electromagnets 31 can ensure the fitting effect with the workpiece and ensure the stability of the connection.

[0027] Furthermore, the interval between the distance separating frames 25 is the interval of the tooling. To ensure that the tooling can clamp, it is necessary to control the interval between the distance separating frames 25 so as to correspond to the interval of the tooling. Among them, a motor 27 is installed above the connecting frame 22. The number of motors 27 corresponds to the number of distance separating frames 25. Any one motor 27 controls any one of the distance separating frames 25 to move independently, so as to better control the interval. The motor 27 is connected to a driving screw rod 26. In this application, a cavity 27 is provided at the lower end of the connecting frame 25. The driving screw rod 26 is located in the cavity 27. The driving screw rod 26 is threadedly connected to the distance separating frame 25. By adjusting the forward and reverse rotation of the driving screw rod 26, the movement control of the distance separating frame 25 is realized. At the same time, one end of the driving screw rod 26 is connected to the motor 27. In this application, the driving screw rod 26 and the motor 27 are respectively located above and below the connecting frame 22. The motor 27 and the driving screw rod 26 are connected by a belt drive. Both ends of the driving screw rod 26 are connected to the connecting frame 22 through the mounting table 24 to prevent falling.

[0028] As Figure 4 shown, a detection component is further provided on the grasping tooling 21. Whether the corresponding workpiece is grasped is judged through the detection component, and whether the connection falls off is judged during the movement process. In this application, the detection component includes an induction piece 37. In this application, a control module is further included. The control module is communicatively connected to the induction piece 37, the motor 27, and the electromagnet 31 to control the grasping and detection work of the workpiece. The induction piece 37 is installed above the distance separating frame 25. A movable rod 34 is provided on the distance separating frame 25. The upper end of the movable rod 34 can come into contact with and separate from the induction piece 37. The lower end of the movable rod 34 contacts the workpiece during work. To ensure more accurate detection effect, the lower end of the movable rod 34 is located between the two electromagnets 31 at one end of the distance separating frame 25.

[0029] A positioning block 36 is fixedly installed on the spacing frame 25. The positioning block 36 is slidably connected to the movable rod 34. At the same time, a second spring 35 is provided between the positioning block 36 and the movable rod 34. The second spring 35 cooperates with the gravity to keep the movable rod 34 in a vertically downward state all the time. Only after contacting the workpiece can the movable rod 34 move upward to ensure the accurate detection effect.

[0030] The above embodiments only express several implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
