Description

Technical Field

[0001] This utility model relates to the field of battery component manufacturing, and in particular to a rubber strip feeding and switching device. Background Technology

[0002] Before lamination, photovoltaic modules are typically secured with adhesive strips. Once the adhesive strips on the module roll are used up, the entire roll needs to be replaced. This replacement requires stopping the feeding process, significantly reducing production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a rubber strip feeding and switching device that enables continuous feeding of rubber strips and improves production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a rubber strip feeding and switching device, including at least two feeding units and a discharging unit that supplies material to the feeding units. The feeding units sequentially and individually obtain material from the discharging unit and connect to the next material obtaining station.

[0005] Compared with the prior art, the embodiment of this utility model has at least two feeding units. Therefore, when one feeding unit is short of material, other feeding units can be replaced to obtain material, so as to realize continuous feeding of rubber strips and improve production efficiency.

[0006] Specifically, the feeding unit includes a pressing assembly for pressing the adhesive strip. The pressing assembly presses the adhesive strip to facilitate connection to the next material receiving station.

[0007] Preferably, the feeding unit further includes: a guiding component and a feeding component for transferring the adhesive strip to the guiding component; the guiding component has a transfer channel through which the adhesive strip passes. The feeding component and the guiding component together guide the transfer direction of the adhesive strip, facilitating the transfer of the adhesive strip.

[0008] Specifically, the guiding component is located between the feeding component and the clamping component, and the clamping component is disposed on the side of the guiding component facing the next material receiving station. The adhesive strip is conveyed to the clamping component via the feeding component and the guiding component, and the clamping component clamps the adhesive strip, so that when the feeding unit is driven to the working position, it can quickly connect to the next material receiving station.

[0009] Preferably, the guide assembly also has an adjustment section for adjusting the transmission channel. This allows for the transmission of rubber strips of different widths.

[0010] Specifically, each of the feeding units corresponds to at least one discharging unit. Each feeding unit can obtain material from the corresponding discharging unit and connect to the next material receiving station, thereby ensuring that the replacement of the feeding unit will not affect the transfer of the adhesive strip.

[0011] Specifically, the feeding units are arranged vertically from top to bottom. This allows for convenient and rapid replacement of the feeding units, reduces the space occupied by the adhesive strip feeding switching device, and saves production costs.

[0012] Preferably, the adhesive strip feeding switching device further includes a lifting power unit that drives each feeding unit to move up and down. The lifting power unit facilitates quick switching between feeding units. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0022] The present invention relates to a rubber strip feeding and switching device, comprising at least two feeding units and a feeding unit 1 for feeding the feeding units. The feeding units sequentially obtain materials from the feeding unit 1 and connect to the next material obtaining station.

[0023] As can be seen from the above, since there are at least two feeding units, when one feeding unit is short of material, other feeding units can be used to obtain material, so as to achieve continuous feeding of rubber strips and thus effectively improve production efficiency.

[0024] Specifically, in this embodiment, such as Figure 1 , Figure 2 As shown, there are two feeding units 1 and two loading units, with the two loading units arranged vertically from top to bottom. Correspondingly, the two feeding units 1 are arranged vertically opposite each other. Each feeding unit 1 can provide four adhesive strips. The upper loading unit transfers the adhesive strips from the upper feeding unit 1, and the lower feeding unit transfers the adhesive strips from the lower feeding unit 1. Figure 1 , Figure 2 , Figure 3 As shown, the feeding unit includes a clamping assembly 4, a guiding assembly 2, a feeding assembly 3, and a lifting power unit 5. The guiding assembly 2 is located between the feeding assembly 3 and the clamping assembly 4, and has a transmission channel for the adhesive strip. The feeding assembly 3 has a feeding channel that transmits the adhesive strip to the guiding assembly 2, and the clamping assembly 4 clamps the adhesive strip. The feeding assembly 3 and the guiding assembly 2 guide the transmission direction of the adhesive strip, and the clamping assembly 4 clamps the adhesive strip, facilitating its connection with the next workstation. In actual use, one feeding unit can correspond to one unloading unit 1, or multiple unloading units 1. The unloading unit 1 uses a conventional roll rotating frame, which places the roll of material on the rotating shaft to provide the adhesive strip. The lifting power unit 5 includes a mounting frame 51 and a lifting cylinder 52. Each feeding unit is mounted on the mounting frame 51, and the lifting cylinder 52 is connected to the mounting frame 51 and drives the mounting frame 51 to move up and down vertically, so that two feeding units are sequentially moved to the working position to provide the adhesive strip. In actual use, the process of switching between the lifting power unit 5 and the feeding unit can be manually controlled by the staff, or it can be automatically controlled by connecting to a PLC or other main control system.

[0025] It is worth noting that in this embodiment, the guide assembly 2 includes a positioning part 21 and an adjusting part 22, wherein the positioning part 21 is disposed on the mounting bracket 51, and the adjusting part 22 is slidably disposed on the positioning part 21. Specifically, as Figure 4 , Figure 5 , Figure 6 As shown, the adjusting part 22 includes five guide posts 221 and five adjusting nuts 222, with a transmission channel for the rubber strip formed between adjacent guide posts 221. Figure 4 , Figure 6 As shown, the positioning part 21 includes: a fixing plate 211 with a U-shaped groove, a lower positioning plate 212 disposed in the U-shaped groove, and an upper positioning plate 213 disposed opposite to the lower positioning plate 212. Both the upper positioning plate 213 and the lower positioning plate 212 have five sets of waist-shaped holes 214. The upper positioning plate 213 has a groove on the side facing the lower positioning plate 212, and the groove of the upper positioning plate 213 and the lower positioning plate 212 enclose a region through which the adhesive strip passes. The lower positioning plate 212 has a protrusion 215 on its side wall of the oblong hole 214. The side of the protrusion 215 facing the upper positioning plate 213 abuts against the corresponding guide post 221, while the side of the protrusion 215 away from the upper positioning plate 213 forms a receiving groove for accommodating the adjusting nut 222. After the guide post 221 passes through the oblong hole 214 on both the upper and lower positioning plates 213 and 212, the adjusting nut 222 is locked and fixed to the guide post 221 and enters the receiving groove of the lower positioning plate 212. When the width of the rubber strip to be transferred changes, the width of the transfer channel can be changed by loosening the adjusting nut 222 and adjusting the position of the guide post 221 in the oblong hole 214. After the guide post 221 is adjusted to the appropriate position, the adjusting nut locks the guide post to the lower positioning plate, ensuring that the width of the transfer channel is fixed, thus facilitating the transfer of rubber strips of different widths. In actual use, the upper positioning plate 213 and the lower positioning plate 212 can also be constructed from a single piece of plate, with through holes for the rubber strips to pass through at corresponding positions. The number of oblong holes 214, guide posts 221, and adjusting nuts 222 can be adjusted according to the number of rubber strips to be transferred. Furthermore, the adjustment method between the adjusting part 22 and the positioning part 21 can be adaptively adjusted according to actual conditions. For example, a slide rail can be provided on the positioning part 21, and the adjusting part 22 can use guide posts that can slide along the slide rail. By sliding, the distance between adjacent guide posts can be adjusted, thus facilitating the transfer of rubber strips of different widths. Of course, the adjusting part 22 can also adopt other adjustable structures depending on the application.

[0026] In addition, such as Figure 4As shown, the feeding assembly 3 includes a rotating shaft 31 and a sleeve 32. The rotating shaft 31 is detachably mounted on the mounting bracket 51. The sleeve 32 is fitted onto the rotating shaft 31 and can rotate around the rotating shaft 31. The sleeve 32 is provided with five guide wheels 33, and a feeding channel for the rubber strip is formed between two adjacent guide wheels 33. When the width of the rubber strip to be conveyed changes, the spacing of the feeding channel can be changed by replacing the sleeve 32. In actual use, the feeding assembly 3 can also adopt other structures. For example, several rollers can be fitted onto the rotating shaft 31, with the rubber strip passing between two adjacent rollers. When the width of the rubber strip changes, the spacing of the feeding channel can be adjusted by adjusting the position of the rollers.

[0027] Furthermore, since the feeding units are vertically arranged and the adhesive strip is a flexible strip, the adhesive strip is prone to drooping during the process of the upper unloading unit transferring it to the feeding assembly. Preferably, in this embodiment, as... Figure 3 , Figure 4 As shown, a support plate 6 is also provided on the upper feeding unit, located at the lower end of the feeding assembly 3. Specifically, the support plate 6 includes a vertical section 61 set on the fixed plate 211, an inclined section 62 supporting the rubber strip, and a horizontal section 63 connecting the vertical section 61 and the inclined section 62. Five through holes are equidistantly opened along the length of the horizontal section 63, each corresponding to a guide wheel 33 on the sleeve. The width of the through holes is greater than the width of the guide wheel 33, ensuring that the support plate 6 does not need to be replaced when the sleeve is replaced due to changes in the width of the rubber strip. The inclined section 62 is inclined from the horizontal section 63 toward the unloading unit 1. The rubber strip is supported by the inclined section 62 of the support plate 6, which can effectively prevent the rubber strip from drooping and ensure smooth conveying of the rubber strip. In actual use, support plates 6 can also be set on each feeding unit, and the number and arrangement of support plates 6 can be adjusted according to the actual situation.

[0028] It should be noted that, in this embodiment, as Figure 4As shown, the clamping assembly 4 includes a clamping cylinder 41, a pressure plate 42, a pressure rod 43, a pressure block 44, and a spring 45. Specifically, the clamping cylinder 41 is mounted on the mounting bracket 51, the pressure plate 42 is connected to the clamping cylinder 41, the spring 45 is sleeved on the pressure rod 43 and connects the pressure plate 42 and the pressure block 44, the pressure rod 43 is slidably mounted on the pressure plate 42, and the pressure block 44 is located on the side of the pressure rod 43 away from the pressure plate 42 and is used to clamp the adhesive strip. When it is necessary to clamp the adhesive strip, the clamping cylinder 41 drives the pressure plate 42 to descend, the pressure block 44 contacts the adhesive strip first, the pressure plate 42 continues to move downward along the pressure rod 43, the spring 45 is compressed, and at the same time the adhesive strip is pressed by the pressure block 44 onto the fixing plate 211 of the positioning part 21. Furthermore, in this embodiment, two clamping cylinders 41 are provided. Each clamping cylinder 41 corresponds to a pressure plate 42, two pressure rods 43, two springs 45, and two pressure blocks 44, so that when any one of the clamping cylinders 41 is working, it can clamp two rubber strips at the same time.

[0029] Furthermore, such as Figure 7 As shown, in this embodiment, the adhesive strip feeding device further includes several through-beam photoelectric switches 7, each disposed on a feeding unit 1. Specifically, through-beam photoelectric switches 7 are respectively disposed on both sides of the feeding unit 1. The through-beam photoelectric switches 7 on both sides emit and receive light from each other. When two through-beam photoelectric switches 7 do not receive light from each other, it indicates that there is still adhesive strip on the roll. When two through-beam photoelectric switches 7 come into contact with each other's light, it indicates that the roll is low on material and needs to be replaced. Therefore, by setting through-beam photoelectric switches 7, a low-material reminder can be achieved at a low cost. In actual use, the position and number of through-beam photoelectric switches 7 can be determined according to the usage situation.

[0030] In addition, such as Figure 1 , Figure 7 As shown, in this embodiment, the adhesive strip feeding device also includes a hot melt machine 8. When the roll is short of material, the adhesive strip at the end of the previous roll and the adhesive strip at the beginning of the next roll are placed at the hot melt machine 8. The hot melt machine 8 heats and melts the two adhesive strips, solidifying them into one piece. Therefore, it is not necessary to manually thread the adhesive strips onto the clamping assembly again, enabling quick roll replacement. The hot melt machine is existing technology and can be purchased and used directly, so it will not be described in detail here.

[0031] The adhesive strip feeding device provided in this embodiment first places a roll of adhesive strip onto two feeding units 1. After the adhesive strip on the roll passes through the corresponding feeding component and guiding component, it is pressed by the pressing component and awaits feeding. Then, the lifting power unit first drives one of the feeding units to start feeding the adhesive strip. The adhesive strip is pulled to the traction platform under the action of the transverse clamping unit. When the roll is short of material, the lifting power unit drives the current feeding unit to stop feeding the adhesive strip and drives the next feeding unit to start feeding the adhesive strip, thus realizing continuous feeding of adhesive strip. During the process of feeding the adhesive strip in the next feeding unit, the roll on the previous feeding unit is quickly replaced by the hot melt machine 8.

[0032] Those skilled in the art will understand that the above embodiments are specific examples of implementing this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
