[0002] At present, in the production process of brazed plate heat exchangers, it is necessary to use a press to press flow channels on the plates, and then stack the plates in an alternating manner for shipment. Before pressing, copper foil used as welding material needs to be compounded on stainless steel and then cut and pressed. In order to prevent the copper foil and the stainless steel plate from separating in subsequent processes, a spot welder is required to perform spot welding on the edge to avoid subsequent separation.

[0003] For example, the patent with the publication number CN110900214A discloses a fully automatic plate-making system for brazed plate heat exchangers, which includes two unwinding devices respectively winding stainless steel plates and copper foils. The compounded stainless steel plates and copper foils are introduced into an automatic constant-length device after passing through an intermediate-frequency spot welding device. In actual use, it is found that the transmission of the tape is completed by the unwinding action of the unwinding mechanism, and the tape cannot be transmitted uniformly and orderly, resulting in poor stability. Summary of the Utility Model

Specific embodiments

[0020] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] In order to improve the stability of the transmission of the composite strip 5, a composite strip transmission mechanism is designed. As Figure 1 shown, it includes a conveying track 1 for conveying the composite strip 5 of stainless steel plate and copper foil. The conveying track 1 has an input end 11 and an output end 12. The composite stainless steel plate and copper foil enter from the input end 11. A spot welding mechanism 2 for welding and fixing the composite strip 5 is provided at the input end 11 of the conveying track 1. A horizontal moving mechanism 3 is provided at the rear end of the conveying track 1 along its conveying direction. The composite strip 5 welded and fixed by the spot welding mechanism 2 is output from the output end 12 through the horizontal moving mechanism 3. Among them, the spot welding mechanism 2 includes a bracket 21 and a cylinder 22 with a spot welding head. The bracket 21 is fixedly arranged outside the conveying track 1, the cylinder 22 is fixedly arranged on the bracket 21, and the spot welding head longitudinally displaces above the conveying track 1 through the cylinder 22. The cylinder 22 drives the spot welding head to perform spot welding and fixing on the overlapped stainless steel plate and copper foil strip. Generally, two spot welding heads are provided and are respectively arranged on both sides of the strip, and the welding effect is good. The patent with the publication number CN110900214A has a detailed description of the spot welding mechanism 2, which will not be elaborated here.

[0022] Two unwinding racks are provided at the input end 11 of the conveying track 1, which are respectively wound with copper foil and stainless steel plate. The copper foil and stainless steel plate are overlapped and placed on the conveying track 1, and are welded and fixed by the spot welding head of the spot welding mechanism 2 to form a composite strip 5. The composite strip 5 is unwound and conveyed under the drive of the horizontal moving mechanism 3.

[0023] Specifically, the horizontal movement mechanism 3 includes a sliding seat 31 and a pressing plate 32. The sliding seat 31 is slidably arranged along the conveying direction of the conveying track 1 through a driving component 4. A longitudinally movable pressing plate 32 is arranged on the sliding seat 31. A material groove 33 through which the composite tape 5 can pass is formed between the pressing plate 32 and the sliding seat 31. The composite tape 5 after spot welding passes through the material groove 33. A cylinder 22 is arranged on the sliding seat 31, and the pressing plate 32 is fixedly connected to the movable end of the cylinder 22. The cylinder 22 drives the pressing plate 32 to move up and down, thereby realizing the clamping of the composite tape 5. After the composite tape 5 is clamped, the driving component 4 is started to drive the sliding seat 31 holding the composite tape 5 to move towards the output end 12.

[0024] As Figure 2 shown, the driving component 4 includes a screw 41 and a motor 42. A groove 13 for accommodating the screw 41 is formed in the conveying track 1. The motor 42 is arranged at the output end 12 of the conveying track 1. The screw 41 is fixedly connected to the output end 12 of the motor 42. The sliding seat 31 is threadedly connected to the screw 41. When the motor 42 is started, the sliding seat 31 can be driven to move horizontally through the rotation of the screw 41, and the sliding seat 31 can be locked after the movement is completed.

[0025] After the spot welding mechanism 2 completes the spot welding of the composite structure of the copper foil and the stainless steel plate, the cylinder 22 is started to drive the pressing plate 32 to move downwards, so that the pressing plate 32 and the sliding seat 31 clamp the composite tape 5. After the clamping is completed, the driving component 4 is started to drive the sliding seat 31 to move towards the output end 12, and the composite tape 5 can be driven to unwind and convey. The composite tape 5 after spot welding can be stably conveyed. During the conveying process, since the copper foil and the stainless steel plate are conveyed as a whole, the displacement error is small, and the structure is relatively simple, and the production cost is low.

[0026] A guiding groove communicating with the material groove 33 is further arranged on the sliding seat 31. Guiding blocks 34 are symmetrically arranged on both sides of the guiding groove. The composite tape 5 passes through between the two guiding blocks 34. The arrangement of the guiding groove and the guiding blocks 34 can ensure the stable conveying of the composite tape 5 in the middle.

[0027] The guiding blocks 34 are arranged on the sliding seat 31 through screws 35. A waist-shaped groove 36 for the two guiding blocks 34 to approach or move away from each other is arranged on the guiding blocks 34. The screws 35 are placed in the waist-shaped groove 36. The guiding blocks 34 are slidably connected to the outside of the two screws 35 through the two waist-shaped grooves 36, and the distance between the two guiding blocks 34 can be adjusted to adapt to copper foils and stainless steel plates of different widths.

[0028] As Figure 3As shown in the figure, the sliding seat 31 includes a fixing portion 311, a positioning portion 312 and a material guiding portion 313 which are connected in sequence. The fixing portion 311 is slidably disposed in the groove 13, and the positioning portion 312 is erected on the groove 13. The fixing portion 311 is arranged to fit the groove 13 of the conveying track 1, so that the stability of the cooperation with the screw 41 for transmission is good. The width of the positioning portion 312 is greater than the width of the groove 13, so that the whole sliding seat 31 is stably erected above the groove 13, further ensuring the stability of the transmission of the sliding seat 31.

[0029] The above description is illustrative rather than restrictive to the present utility model. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all of them will fall within the protection scope of the present utility model.
