Description

Technical Field

[0001] This utility model relates to the field of battery cell stacking technology, specifically to a welding rod conveying device for a stacking welding machine. Background Technology

[0002] As the demand for photovoltaic new energy continues to grow, cost reduction and efficiency improvement of photovoltaic products have become their core competitiveness. This requires new technological changes to drive this development.

[0003] Photovoltaic shingling machines are core equipment in the manufacturing process of solar cells. A photovoltaic shingling machine utilizes the inherent characteristics of photovoltaic cells to weld electrodes of different materials together with the cells using heat and pressure. Through the action of heat and pressure, the shingling machine welds the electrodes to the cells, thereby forming a solar cell module. For example, Chinese patent application number 202410484631.9, published on July 12, 2024, discloses an automated photovoltaic flexible module shingling machine. The busbar unwinding and cutting mechanism of this shingling machine can cut the busbars to the required length for each shingling operation.

[0004] However, as described in the document, after the cutting mechanism cuts the welding rod, the cut surface of the welding rod remains at the cutting position. Due to the cutting method, the cut surface of the welding rod is close to the cutting position. Since the front end of the gripping mechanism has a certain length, this length limits the distance between the gripping mechanism and the welding rod. As a result, when the gripping mechanism wants to grip the next welding rod, it cannot grip the welding rod well, thus affecting efficiency. Utility Model Content

[0005] This utility model provides a welding rod conveying device for a lap welding machine, which enables the welding rod cutting component to avoid the cutting surface of the welding rod, thereby facilitating the welding rod gripping component to grip the welding rod for the next time.

[0006] To achieve the above objectives, a welding electrode conveying device for a lap welding machine includes a welding electrode frame and a welding electrode conveying mechanism on the welding electrode frame. The welding electrode conveying mechanism is used to convey welding electrodes to a welding electrode placement platform located on the welding electrode frame. The welding electrode conveying mechanism includes a welding electrode conveying base, a welding electrode gripping component, and a welding electrode cutting component. The welding electrode conveying base is located on the welding electrode frame at one end of the welding electrode placement platform. The welding electrode cutting component is set on the welding electrode conveying base through a cutting position adjustment component. The welding electrode gripping component is located on the welding electrode frame above the welding electrode placement platform and moves along both ends of the welding electrode placement platform. The welding electrode passes through the welding electrode cutting component and is gripped by the welding electrode gripping component. After the welding electrode is cut, the cutting position adjustment component drives the welding electrode cutting component to retract towards the side of the welding electrode conveying base away from the welding electrode placement platform.

[0007] In the above structure, the electrode cutting assembly is mounted on the electrode conveying base via a cutting position adjustment assembly. The cutting position adjustment assembly drives the electrode cutting assembly to extend and retract towards the electrode placement platform side of the electrode conveying base. This allows the electrode cutting assembly to retract after cutting the electrode. As the upper and lower parts of the electrode cutting assembly retract, the electrode remains stationary, causing the cut surface of the electrode to extend relatively outward. This facilitates the electrode gripping assembly in gripping the next electrode. Once the next electrode is gripped and pulled to a suitable length, the cutting position adjustment assembly drives the electrode cutting assembly to extend a certain distance and continue cutting the electrode. The cycle repeats after cutting, ensuring that the electrode cutting assembly does not obstruct the electrode gripping assembly, resulting in high electrode conveying efficiency.

[0008] Furthermore, the cutting position adjustment assembly includes a cutting position adjustment cylinder and a cutting position adjustment connecting block. The cutting position adjustment cylinder is located at the rear end of the welding rod conveying base. The cutting position adjustment connecting block is provided on the piston rod of the cutting position adjustment cylinder, and the welding rod cutting assembly is provided on the cutting position adjustment connecting block.

[0009] The above settings ensure that the electrode cutting component will not obstruct the electrode gripping component by using a cylinder to adjust the cutting position to drive the electrode cutting component to extend and retract.

[0010] Furthermore, a position adjustment limiting groove is provided on the welding rod conveying base, and the cutting position adjustment connecting block is located in the position adjustment limiting groove.

[0011] The above settings, through the position adjustment limit groove, limit the extension and retraction distance of the welding rod cutting assembly, preventing excessive movement that could affect the feeding of the welding rod.

[0012] Furthermore, the electrode cutting assembly includes an electrode cutting base, an electrode cutting cylinder, an electrode cutting drive rod, and an electrode cutter. The electrode cutting base is mounted on a cutting position adjustment connecting block. An electrode cutting worktable is located at the lower end of the electrode cutting base, and an electrode cutting plate is located on the outer side of the electrode cutting worktable. The electrode is placed on the electrode cutting worktable and passes through the electrode cutting plate. An electrode cutting cylinder is located at the top of the electrode cutting base, and an electrode cutting connecting block is located on the piston rod of the electrode cutting cylinder. The center of the electrode cutting drive rod is hinged to the electrode cutting base, and one end of the electrode cutting drive rod is hinged to the electrode cutting connecting block. The electrode cutter is located at the other end of the electrode cutting drive rod, and the back of the electrode cutter is in contact with the electrode cutting plate.

[0013] With the above setup, when the electrode cutting cylinder retracts, it causes one end of the electrode cutting drive rod to swing upward, which in turn causes the other end of the electrode cutting drive rod to swing downward, thereby driving the electrode cutter to move downward to cut the electrode.

[0014] Furthermore, a cutting limit roller is provided on the welding rod cutting base above the welding rod cutting worktable, and the welding rod is located between the cutting limit roller and the welding rod cutting worktable, with the cutting limit roller and the welding rod in rolling connection.

[0015] The above settings, by setting a cutting limit roller, limit the movement of the welding rod and prevent it from moving randomly.

[0016] Furthermore, the electrode gripping assembly includes an electrode gripping cylinder, an electrode gripping connecting block, a first electrode gripping clamp, a second electrode gripping clamp, an electrode gripping base plate, and an electrode gripping slider. An electrode gripping guide rail is provided on the electrode frame on one side of the electrode placement platform. The electrode gripping base plate is slidably mounted on the electrode gripping guide rail via the electrode gripping slider. An electrode gripping cylinder is provided on the electrode gripping base plate. The electrode gripping connecting block is hinged to the piston rod of the electrode gripping cylinder. A second electrode gripping clamp is provided on the side wall of the electrode gripping base plate above the electrode placement platform. One end of the first electrode gripping clamp is hinged to the electrode gripping base plate, and the other end is hinged to the electrode gripping connecting block. The first and second electrode gripping clamps are correspondingly arranged. An electrode gripping drive module for driving the electrode gripping slider to move is also provided on the electrode frame.

[0017] The above configuration involves the electrode gripping cylinder driving the electrode gripping connecting block to extend and retract, causing the first electrode gripping clamp to swing up and down, thus creating an opening between the first and second electrode gripping clamps for gripping the electrode. This facilitates electrode gripping. When the electrode gripping cylinder extends and retracts, the first electrode gripping clamp swings around the hinge point with the electrode gripping substrate, thereby creating an opening between the first and second electrode gripping clamps.

[0018] Furthermore, a welding rod fixing assembly is provided on the side of the welding rod conveying base away from the welding rod placement platform. The welding rod fixing assembly includes a welding rod fixing cylinder, a welding rod fixing connecting block, and a welding rod fixing plate. The welding rod fixing cylinder is located at the top of the welding rod conveying base. A welding rod fixing connecting block is provided on the piston rod of the welding rod fixing cylinder. A welding rod fixing seat is provided at the lower end of the welding rod conveying base. The center of the welding rod fixing plate is hinged to the welding rod conveying base above the welding rod fixing seat. One end of the welding rod fixing plate is hinged to the welding rod fixing connecting block. A welding rod is provided between the other end of the welding rod fixing plate and the welding rod fixing seat.

[0019] The above configuration allows the electrode fixing cylinder to retract, causing one end of the electrode fixing plate to swing upwards, which in turn causes the other end of the electrode fixing plate to swing downwards and press and fix the electrode. This prevents the electrode from moving around when the electrode cutting assembly is extended and retracted by the adjusting cylinder at the cutting position. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-4 As shown, a welding electrode conveying device for a lap welding machine includes a welding electrode frame 1z, on which a welding electrode conveying mechanism 2z is provided. The welding electrode conveying mechanism 2z is used to convey welding electrodes 01z to a welding electrode placement platform 11z located on the welding electrode frame 1z. The welding electrode conveying mechanism 2z includes a welding electrode conveying base 21z, a welding electrode gripping assembly 3z, and a welding electrode cutting assembly 4z. The welding electrode conveying base 21z is provided on the welding electrode frame 1z at one end of the welding electrode placement platform 11z. The welding electrode cutting assembly... The electrode 3z is set on the electrode feeding base 21z by the cutting position adjustment component 5z. The electrode gripping component 3z is located on the electrode frame 1z above the electrode placement platform 11z and moves along both ends of the electrode placement platform 11z. The electrode 01z passes through the electrode cutting component 4z and is gripped by the electrode gripping component 3z. After the electrode is cut, the cutting position adjustment component 5z drives the electrode cutting component 4z to retract towards the side of the electrode feeding base 21z away from the electrode placement platform 11z.

[0026] like Figure 2 As shown, the cutting position adjustment assembly 5z includes a cutting position adjustment cylinder 51z and a cutting position adjustment connecting block 52z. The cutting position adjustment cylinder 51z is located at the rear end of the welding rod conveying base 21z. The cutting position adjustment connecting block 52z is provided on the piston rod of the cutting position adjustment cylinder 51z, and the welding rod cutting assembly 4z is provided on the cutting position adjustment connecting block 52z. The cutting position adjustment cylinder 51z drives the welding rod cutting assembly 4z to extend and retract, thereby ensuring that the welding rod cutting assembly 4z will not obstruct the welding rod gripping assembly 3z.

[0027] In this embodiment, a reinforcing rib 521z is provided on the cutting position adjustment connecting block 52z, which makes the cutting position adjustment connecting block 52z stronger.

[0028] A position adjustment limiting groove 53z is provided on the electrode conveying base 21z, and the cutting position adjustment connecting block 52z is located within the position adjustment limiting groove 53z. The position adjustment limiting groove 53z limits the extension and retraction distance of the electrode cutting assembly 4z, preventing excessive movement that could affect the conveying of the electrode 01z.

[0029] like Figure 3 and Figure 4 As shown, the electrode cutting assembly 4z includes an electrode cutting base 41z, an electrode cutting cylinder 42z, an electrode cutting drive rod 43z, and an electrode cutter 44z. The electrode cutting base 41z is mounted on the cutting position adjustment connecting block 52z. An electrode cutting worktable 40z is provided at the lower end of the electrode cutting base 41z, and an electrode cutting plate 45z is provided on the outer side of the electrode cutting worktable 40z. The electrode 01z is placed on the electrode cutting worktable 40z and passes through the electrode cutting plate 45z. A welding electrode cutting cylinder 42z is provided at the top of the welding electrode cutting base 41z. A welding electrode cutting connecting block 46z is provided on the piston rod of the welding electrode cutting cylinder 42z. The center of the welding electrode cutting drive rod 43z is hinged to the welding electrode cutting base 41z, and one end of the welding electrode cutting drive rod 43z is hinged to the welding electrode cutting connecting block 46z. The welding electrode cutter 44z is provided at the other end of the welding electrode cutting drive rod 43z, and the back of the welding electrode cutter 44z is in contact with the welding electrode cutting plate 45z. When the welding electrode cutting cylinder 42z retracts, it drives one end of the welding electrode cutting drive rod 43z to swing upward, which in turn drives the other end of the welding electrode cutting drive rod 43z to swing downward, thereby driving the welding electrode cutter 44z to move downward to cut the welding electrode 01z.

[0030] In this embodiment, a cutting guide groove 211z is provided on the electrode conveying base 21z, and a cutting guide strip (not shown in the figure) corresponding to the cutting guide groove 211z is provided on the back of the electrode cutting base 41z. The cutting guide strip is slidably disposed in the cutting guide groove 211z. The cutting guide groove 211z enables the electrode cutting base 41z to move by the cutting position adjusting cylinder 51z.

[0031] like Figure 3 and Figure 4As shown, a cutting limiting roller 47z is provided on the welding rod cutting base 41z above the welding rod cutting worktable 40z. The welding rod 01z is located between the cutting limiting roller 47z and the welding rod cutting worktable 40z, and the cutting limiting roller 47z is in rolling connection with the welding rod 01z. By setting the cutting limiting roller 47z, the welding rod 01z is limited in its movement, preventing it from moving randomly.

[0032] like Figures 2-4 As shown, the electrode gripping assembly 3z includes an electrode gripping cylinder 31z, an electrode gripping connecting block 32z, a first electrode gripping clamping plate 33z, a second electrode gripping clamping plate 34z, an electrode gripping base plate 35z, and an electrode gripping slider 36z. An electrode gripping guide rail 37z is provided on the electrode frame 1z on one side of the electrode placement platform 11z. The electrode gripping base plate 35z is slidably mounted on the electrode gripping guide rail 37z via the electrode gripping slider 36z. The electrode gripping cylinder 31z is provided on the electrode gripping base plate 35z, and the electrode gripping connecting block 32z is hinged to the piston of the electrode gripping cylinder 31z. On the rod, a second electrode gripping clamp 34z is provided on the side wall of the electrode gripping base plate 35z above the electrode placement platform 11z. One end of the first electrode gripping clamp 33z is hinged to the electrode gripping base plate 35z, and the other end of the first electrode gripping clamp 33z is hinged to the electrode gripping connecting block 32z. The first electrode gripping clamp 33z and the second electrode gripping clamp 34z are correspondingly arranged. An electrode gripping drive module (not shown in the figure) for driving the electrode gripping slider 36z to move is also provided on the electrode frame 1z. In this embodiment, the electrode gripping drive module is a drive component such as a motor or cylinder. The electrode gripping cylinder 31z drives the electrode gripping connecting block 32z to extend and retract, and causes the electrode gripping first clamping plate 33z to swing up and down, so that an opening for gripping the electrode 01z is formed between the electrode gripping first clamping plate 33z and the electrode gripping second clamping plate 34z. This facilitates the gripping of the electrode 01z. When the electrode gripping cylinder 31z extends and retracts, the electrode gripping first clamping plate 33z swings around the hinge point with the electrode gripping base plate 35z as the fulcrum, thereby forming an opening between the electrode gripping first clamping plate 33z and the electrode gripping second clamping plate 34z.

[0033] like Figure 3 and Figure 4As shown, a welding rod fixing assembly 6z is provided on the side of the welding rod feeding base 21z away from the welding rod placement platform 11z. The welding rod fixing assembly 6z includes a welding rod fixing cylinder 61z, a welding rod fixing connecting block 62z, and a welding rod fixing plate 63z. The welding rod fixing cylinder 61z is located at the top of the welding rod feeding base 21z. The welding rod fixing connecting block 62z is provided on the piston rod of the welding rod fixing cylinder 61z. A welding rod fixing seat 64z is provided at the lower end of the welding rod feeding base 21z. The center of the welding rod fixing plate 63z is hinged to the welding rod feeding base 21z above the welding rod fixing seat 64z. One end of the welding rod fixing plate 63z is hinged to the welding rod fixing connecting block 62z. A welding rod is provided between the other end of the welding rod fixing plate 63z and the welding rod fixing seat 64z. When the electrode fixing cylinder 61z retracts, it causes one end of the electrode fixing plate 63z to swing upward, which in turn causes the other end of the electrode fixing plate 63z to swing downward and press and fix the electrode 01z. This makes it easier to prevent the electrode 01z from moving around when the electrode cutting assembly 4z is extended and retracted by the adjusting cylinder 51z at the cutting position.

[0034] like Figure 3 As shown, in this embodiment, a set of one or more limiting roller groups 22z are provided on the electrode conveying base 21z along the moving direction of the electrode 01z. The limiting roller group 22z has two limiting rollers. The electrode 01z is located between the two limiting rollers and the limiting rollers are in rolling connection with the electrode. The limiting rollers limit the moving direction of the electrode to prevent the electrode from deviating.

[0035] The working principle of this utility model is as follows: The electrode cutting component 4z is set on the electrode conveying base 21z through the cutting position adjustment component 5z. The cutting position adjustment component 5z drives the electrode cutting component 4z to extend and retract towards the side of the electrode conveying base 21z closer to the electrode placement platform 11z. Thus, after the electrode cutting component 4z cuts the electrode 01z, the cutting position adjustment component 5z drives the electrode cutting component 4z to retract. Since the upper and lower parts of the electrode cutting component retract backward, the electrode does not move, so the position of the electrode cutting surface extends outward. This makes it convenient for the electrode gripping component 3z to grip the next electrode 01z. After the next electrode 01z is gripped and pulled out to a suitable length, the cutting position adjustment component 5z drives the electrode cutting component 4z to extend a certain distance and continue cutting the electrode 01z. After cutting, it retracts to complete the cycle. This ensures that the electrode cutting component 4z does not obstruct the work of the electrode gripping component 3z, resulting in high electrode conveying efficiency.
