Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic module production equipment, and more particularly to a distance adjusting mechanism and a film placing device. BACKGROUND

[0002] A photovoltaic module is usually encapsulated by a back sheet, a lower adhesive film, a cell string group, an upper adhesive film and a glass sheet. There is a gap between two adjacent cell pieces in the cell string group and between two adjacent cell strings. Light energy irradiated to the gaps is difficult to be directly absorbed or utilized. In order to improve the utilization rate of light energy, a reflective film strip is attached to the corresponding position of the back sheet corresponding to the inter-piece and inter-string gap. The light energy irradiated to the above-mentioned gap position is reflected to the glass sheet by the reflective film strip, and then reflected to the cell piece by the glass sheet, so as to fully utilize the light energy at the gap.

[0003] In the prior art, a plurality of reflective film strips are simultaneously unwound by a plurality of film placing heads at a predetermined film strip distance. Each film placing head is responsible for placing one reflective film strip. However, the distance between two adjacent reflective film strips is different for different sizes of back sheets. The distance between the film placing heads needs to be adjusted accordingly each time the back sheet type is changed. However, the distance between the existing film placing heads is usually adjusted manually, which is low in efficiency. CONTENT OF THE UTILITY MODEL

[0004] In order to solve at least one of the above technical problems, the present application provides a distance adjusting mechanism and a film placing device, which adopts the following technical solutions:

[0005] In a first aspect, examples of the present application provide a distance adjusting mechanism, which comprises a mounting frame, a transverse driving assembly, an extension assembly, a plurality of adjusting plates and a plurality of positioning assemblies, wherein:

[0006] The plurality of adjusting plates are arranged at intervals along a first direction and are slidably mounted on the mounting frame along the first direction respectively. The adjusting plates are used to mount the film placing heads.

[0007] Each adjusting plate is elastically connected to each positioning assembly one by one. The adjusting plate can be adsorbed on the mounting frame by the positioning assembly.

[0008] The transverse driving assembly is mounted on the mounting frame, and the extension assembly is mounted on the driving end of the transverse driving assembly. The transverse driving assembly is configured to drive the extension assembly to move along the first direction, so that the extension assembly moves to the corresponding positioning assembly of the adjusting plate to be adjusted.

[0009] The extension end of the extension assembly is configured to drive the positioning assembly away from the mounting frame along a second direction to release the adsorption of the positioning assembly on the mounting frame. The second direction is perpendicular to the first direction.

[0010] The telescopic end of the telescopic assembly is further configured to be separated from the positioning assembly, so that the positioning assembly rebounds to restore the adsorption to the mounting rack.

[0011] The distance adjustment mechanism provided by the present application realizes the position adjustment of the film placing head through the mounting rack, the horizontal movement driving assembly, the telescopic assembly, the plurality of adjustment plates and the plurality of positioning assemblies. This design effectively solves the problem of low efficiency of manually adjusting the distance between the film placing heads. The mounting rack serves as the basis of the entire mechanism and provides stable support for each component. The adjustment plate is slidably mounted on the mounting rack along the first direction. In this way, each film placing head can be freely moved along the first direction independently, thereby adapting to back plates of different sizes. The combination of the horizontal movement driving assembly and the telescopic assembly makes the distance adjustment of the adjustment plate more automated. The horizontal movement driving assembly accurately moves the telescopic assembly to the position of the adjustment plate to be adjusted, and the telescopic end of the telescopic assembly temporarily separates the positioning assembly from the mounting rack by moving along the second direction, allowing the adjustment plate to slide freely. After adjustment, the telescopic end of the telescopic assembly is separated from the positioning assembly, and the positioning assembly rebounds to the original position through the elastic connection and is adsorbed on the mounting rack again. This automated adjustment not only greatly improves the production efficiency, but also reduces the error of manual operation, ensures the accuracy of the distance between the film placing heads, and ultimately improves the attachment quality of the reflective film strip and the light energy utilization rate of the photovoltaic module.

[0012] According to some examples of the first aspect of the present application, the horizontal movement driving assembly comprises a motor, a gear, a rack and a moving plate, wherein:

[0013] The moving plate is slidably mounted on the mounting rack along the first direction;

[0014] The rack is mounted on the mounting rack and extends along the first direction;

[0015] The motor is mounted on the moving plate, and the gear is mounted on the driving end of the motor and engaged with the rack;

[0016] The telescopic assembly is mounted on the moving plate.

[0017] The specific structure of the transverse drive assembly is further described here, including a motor, a gear, a rack, and a moving plate. This design not only improves the accuracy of the pitch adjustment, but also enhances the reliability and automation of the system. The motor serves as the power source, and its high precision and programmability ensure accurate control of the transverse drive assembly. The combination of the gear and the rack converts the rotational motion of the motor into linear motion, allowing the moving plate to slide in the first direction. The moving plate serves as the carrier of the telescopic assembly, and through its sliding, the telescopic assembly can accurately reach the position of the adjustment plate to be adjusted. This structure not only simplifies the system design, but also ensures the stability and accuracy of the entire adjustment process. The high-precision transmission characteristics of the gear and the rack allow the movement position of each adjustment plate to be accurately controlled, reducing the problem of film strip attachment caused by inaccurate adjustment plate positions.

[0018] According to some examples of the first aspect of the present application, the telescopic assembly includes a telescopic drive and a push rod, the push rod is installed at the driving end of the telescopic drive, the telescopic drive is configured to drive the push rod to extend or retract, and the push rod constitutes the telescopic end of the telescopic assembly.

[0019] The structure of the telescopic assembly is specifically described here, including a telescopic drive and a push rod. The telescopic drive, as the driving source of the push rod, can use high-precision and high-response-speed driving devices such as air cylinders and electric cylinders to ensure the accurate extension and retraction of the push rod in the second direction. The push rod, as the telescopic end of the telescopic assembly, its extension and retraction directly affect the adsorption and release of the positioning assembly. When the push rod extends, it pushes the positioning assembly in the second direction, allowing the positioning assembly to temporarily separate from the mounting rack, thereby allowing the adjustment plate to slide freely; when the push rod retracts, it separates from the positioning assembly, and the positioning assembly is reset by elastic connection and re-adsorbs on the mounting rack. This design not only simplifies the mechanism, but also improves the adjustment speed and accuracy. The high reliability of the telescopic drive ensures that each adjustment can be accurately completed, reducing the equipment failure rate.

[0020] According to some examples of the first aspect of the present application, a first insertion hole is formed on each positioning assembly, and the diameter of the leading end of the push rod is less than or equal to the hole diameter of the first insertion hole; the leading end of the push rod can pass through or exit the first insertion hole as the push rod extends or retracts;

[0021] The diameter of the trailing end of the push rod is greater than the hole diameter of the first insertion hole, and the trailing end of the push rod can abut against the outer edge of the first insertion hole as the push rod extends, thereby pushing the positioning assembly away from the mounting rack.

[0022] The structure of the first insertion hole on the positioning assembly and the first end of the push rod is specifically described here. This design not only improves the accuracy of the spacing adjustment, but also enhances the reliability and maintainability of the system. The first end of the push rod has a diameter that is less than or equal to the hole diameter of the first insertion hole, allowing the push rod to smoothly pass through the first insertion hole and achieve precise positioning. When the push rod is extended, its first end passes through the first insertion hole, and then the tail end of the push rod abuts against the outer edge of the first insertion hole, pushing the positioning assembly away from the mounting rack. When the push rod is retracted, its first end exits the first insertion hole, and the positioning assembly returns to its original position and re-adsorbs on the mounting rack. This insertion hole structure not only improves the stability and reliability of the adjustment process, but also simplifies the maintenance and replacement process. The structural design of the push rod makes its influence on the positioning assembly more uniform and stable during extension and retraction, avoiding the problem of adjustment plate deviation or jamming caused by uneven local stress. In addition, the size design of the first end and the tail end of the push rod allows it to more effectively cooperate with the positioning assembly, ensuring efficient and accurate adjustment.

[0023] According to some examples of the first aspect of the present application, the mounting rack includes a rack body and an adsorption plate mounted on the rack body, and the positioning assembly includes a first floating plate, a plurality of magnets, and a plurality of first elastic bodies, wherein:

[0024] The first floating plate is located between the adjustment plate and the adsorption plate;

[0025] One end of the first floating plate away from the adsorption plate is elastically connected to the adjustment plate through the plurality of first elastic bodies;

[0026] The first floating plate is installed with a plurality of magnets at one end close to the adsorption plate, and the first floating plate can be magnetically adsorbed on the adsorption plate through the plurality of magnets;

[0027] The first elastic body is configured to contract when the extension end of the extension assembly pushes the first floating plate in the second direction, causing the first floating plate to move closer to the adjustment plate and away from the adsorption plate;

[0028] The first elastic body is also configured to return to its original position when the extension end of the extension assembly separates from the first floating plate, causing the magnets on the first floating plate to be magnetically adsorbed on the adsorption plate.

[0029] The specific structure of the positioning assembly is described herein, including a first floating plate, a plurality of magnets and a plurality of first elastic bodies. This design not only improves the accuracy of the spacing adjustment, but also enhances the stability and reliability of the system. The first floating plate is located between the adjusting plate and the adsorption plate, and is stably fixed on the mounting frame by magnetic adsorption between the magnet and the adsorption plate. This magnetic adsorption method not only has strong adsorption force, but also can maintain stability during production. The first elastic body is contracted when the first floating plate is pushed by the telescopic end of the telescopic assembly, so that the first floating plate is close to the adjusting plate and away from the adsorption plate, thereby releasing the magnetic adsorption. When the telescopic end of the telescopic assembly is separated from the first floating plate, the first elastic body returns to its original position, and the first floating plate is re-adsorbed on the adsorption plate. The first elastic body enables the first floating plate to quickly reset after adjustment, thereby improving the adjustment speed and production efficiency. In addition, this design is also easy to maintain and replace, which reduces the failure rate and maintenance cost of the equipment, and improves the overall reliability and service life of the system.

[0030] According to some examples of the first aspect of the present application, the first elastic body includes a guide rod and a spring, the first floating plate is movably connected to the adjusting plate through the guide rod, and the spring is sleeved on the guide rod between the first floating plate and the adjusting plate, the first end of the spring abuts against the first floating plate, and the second end of the spring abuts against the adjusting plate.

[0031] The structure of the first elastic body is described in detail herein, which includes a guide rod and a spring. When the telescopic end of the telescopic assembly pushes the first floating plate, the spring is compressed, causing the first floating plate to move close to the adjusting plate and away from the adsorption plate. When the telescopic end of the telescopic assembly is separated from the first floating plate, the spring returns to its original position, and the first floating plate is re-adsorbed on the adsorption plate. The high recovery force and uniform stress characteristics of the spring ensure that the first floating plate does not deviate or jam during adjustment, thereby improving the stability and reliability of the system. In addition, the combined design of the guide rod and the spring also facilitates maintenance and replacement, thereby reducing the failure rate and maintenance cost of the equipment and prolonging the service life of the equipment.

[0032] According to some examples of the first aspect of the present application, the positioning assembly includes a second floating plate, a plurality of suction cups and a plurality of second elastic bodies, wherein:

[0033] The second floating plate is located between the adjusting plate and the mounting frame;

[0034] The end of the second floating plate away from the mounting frame is elastically connected to the adjusting plate through the plurality of second elastic bodies;

[0035] The end of the second floating plate close to the mounting frame is installed with a plurality of suction cups, and the second floating plate can be adsorbed on the mounting frame through the plurality of suction cups;

[0036] The second elastic body is configured to contract when the telescopic end of the telescopic assembly pushes the second floating plate in the second direction, so that the second floating plate is close to the adjusting plate and away from the mounting rack;

[0037] The second elastic body is further configured to rebound and reset when the telescopic end of the telescopic assembly is separated from the second floating plate, so that the suction cups on the second floating plate are adsorbed on the mounting rack.

[0038] Another specific structure of the positioning assembly is described herein, which includes a second floating plate, a plurality of suction cups and a plurality of second elastic bodies. This design not only improves the accuracy of spacing adjustment, but also enhances the stability and universality of the system. The second floating plate is located between the adjusting plate and the mounting rack, and the stable fixation of the positioning assembly on the mounting rack is achieved through the suction force between the suction cups and the mounting rack. The use of suction cups makes the suction force strong and uniform, and can maintain stability even on mounting racks with different surface characteristics, improving the universality and adaptability of the system. The second elastic body contracts when the telescopic end of the telescopic assembly pushes the second floating plate, so that the second floating plate is close to the adjusting plate and away from the mounting rack, thereby releasing the suction. When the telescopic end of the telescopic assembly is separated from the second floating plate, the second elastic body rebounds and resets, and the second floating plate is re-adsorbed on the mounting rack by the suction cups. This elastic design ensures smooth adjustment each time, reducing equipment failures caused by sudden release or reset. Overall, this design not only improves the adjustment accuracy, but also enhances the stability and universality of the system, making it suitable for various production environments.

[0039] According to some examples of the first aspect of the application, the spacing adjustment mechanism further comprises a photoelectric sensor and a plurality of sensing pieces;

[0040] The sensing pieces are installed one by one on the adjusting plate;

[0041] The photoelectric sensor is installed on the driving end of the transverse driving assembly, which is used to drive the photoelectric sensor to move to sense the sensing pieces, and the telescopic end of the telescopic assembly is used to push the corresponding positioning assembly after the corresponding sensing piece is sensed.

[0042] The use of photoelectric sensors and sensing sheets in the pitch adjustment mechanism is described herein. The photoelectric sensors are installed on the driving end of the transverse driving assembly, and the sensing sheets are installed one-to-one on the adjustment plates. This design not only improves the accuracy of pitch adjustment, but also enhances the automation level and reliability of the system. When the transverse driving assembly drives the photoelectric sensors to move, the photoelectric sensors can detect the corresponding sensing sheets, thereby determining the positions of multiple adjustment plates through one photoelectric sensor. This position detection method not only has high accuracy, but also has fast response speed, reducing manual intervention during the adjustment process. The extension end of the telescopic assembly pushes the corresponding positioning assembly after the corresponding sensing sheet is sensed, realizing pitch adjustment. The high sensitivity and fast response characteristics of the photoelectric sensor make the adjustment process more rapid and smooth, improving production efficiency.

[0043] According to some examples of the first aspect of the present application, the adjustment plates and the positioning assemblies are arranged on the first side of the mounting frame, the transverse driving assembly and the telescopic assembly are arranged on the second side of the mounting frame, and the mounting frame is provided with an avoiding space extending in the first direction. The positioning assemblies are adsorbed on the mounting frames on the upper and lower sides of the avoiding space.

[0044] When the extension end of the telescopic assembly extends, it passes through the avoiding space to push the positioning assembly away from the mounting frame. When the extension end of the telescopic assembly retracts, it separates from the positioning assembly.

[0045] The arrangement of the pitch adjustment mechanism on the mounting frame is described herein. The adjustment plates and the positioning assemblies are arranged on the first side of the mounting frame, the transverse driving assembly and the telescopic assembly are arranged on the second side of the mounting frame, and the mounting frame is provided with an avoiding space extending in the first direction. This design not only improves the compactness and stability of the system, but also ensures the smooth progress of the pitch adjustment process. The avoiding space allows the extension end of the telescopic assembly to extend through the avoiding space and directly push the positioning assembly away from the mounting frame, and to separate from the positioning assembly when retracted, without affecting the resetting of the positioning assembly. The mounting frame structure on the upper and lower sides of the avoiding space ensures the adsorption area of the positioning assembly, improving the stability and reliability of the adsorption. Overall, this arrangement simplifies the system design and improves the performance and applicability of the pitch adjustment mechanism, making it more suitable for automated production lines.

[0046] In the second aspect, examples of the present application provide a film releasing device, which includes the aforementioned pitch adjustment mechanism and a plurality of film releasing heads. The film releasing heads are installed one-to-one on the adjustment plates, and each film releasing head is used to release one film strip.

[0047] The film releasing device provided by the application comprises the aforementioned spacing adjustment mechanism and a plurality of film releasing heads. This design not only improves the automation degree and reliability of the film releasing device, but also enhances the flexibility and production efficiency of the system. The use of the spacing adjustment mechanism enables the spacing of the film releasing heads to be quickly and accurately adjusted to adapt to back plates of different sizes. The plurality of film releasing heads can simultaneously release a plurality of reflective film strips, thereby improving the film releasing speed and consistency. This design of the film releasing device is not only suitable for large-scale production, but also can flexibly cope with the demand for back plates of different sizes, and has extremely high market competitiveness and application prospect.

[0048] Compared with the prior art, the beneficial effects of the technical scheme of the application are:

[0049] Compared with the prior art in which the spacing adjustment mechanism is manually adjusted by artificial, the application provides a spacing adjustment mechanism and a film releasing device, which can realize the position adjustment of all adjusting plates by using only one horizontal movement driving assembly, simplify the structure of the spacing adjustment mechanism, and reduce the manufacturing and maintenance costs.

[0064] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0065] like Figure 1 As shown, the spacing adjustment mechanism in this embodiment includes a mounting frame 1, a transverse drive assembly 2, a telescopic assembly 3, multiple adjustment plates 4, and multiple positioning assemblies 5, wherein:

[0066] Multiple adjusting plates 4 are spaced apart along the first direction and are slidably mounted on the mounting frame 1 along the first direction. The adjusting plates 4 are used to mount the film-laying head 200.

[0067] Each adjustment plate 4 is elastically connected to each positioning component 5 in a corresponding manner, and the adjustment plate 4 can be adsorbed onto the mounting frame 1 through the positioning component 5;

[0068] The transverse drive assembly 2 is mounted on the mounting bracket 1, and the telescopic assembly 3 is mounted on the drive end of the transverse drive assembly 2. The transverse drive assembly 2 is configured to drive the telescopic assembly 3 to move along the first direction, so that the telescopic assembly 3 moves to the positioning assembly 5 corresponding to the adjustment plate 4 to be adjusted.

[0069] The telescopic end of the telescopic component 3 is configured to drive the positioning component 5 away from the mounting frame 1 along the second direction, so as to release the positioning component 5 from the mounting frame 1; the second direction is perpendicular to the first direction.

[0070] The telescopic end of the telescopic component 3 is also configured to separate from the positioning component 5, so that the positioning component 5 springs back to restore its adhesion to the mounting bracket 1.

[0071] Optionally, the mounting bracket 1 may be made of a high-strength, corrosion-resistant metal, such as aluminum alloy or stainless steel, to ensure its long-term stability and durability. The mounting bracket 1 has multiple mounting holes for mounting other components.

[0072] The distance adjusting mechanism provided by the application adjusts the position of the film placing head 200 through the mounting frame 1, the horizontal movement driving assembly 2, the telescopic assembly 3, the plurality of adjusting plates 4 and the plurality of positioning assemblies 5. This design effectively solves the problem of low efficiency of manually adjusting the distance of the film placing head 200. The mounting frame 1 serves as the basis of the entire mechanism and provides stable support for each component. The adjusting plate 4 is slidably mounted on the mounting frame 1 along the first direction. In this way, each film placing head 200 can be freely moved along the first direction independently, thereby adapting to back plates of different sizes. The combination of the horizontal movement driving assembly 2 and the telescopic assembly 3 makes the distance adjustment of the adjusting plate 4 more automated. The horizontal movement driving assembly 2 accurately moves the telescopic assembly 3 to the position of the adjusting plate 4 to be adjusted, and the telescopic end of the telescopic assembly 3 moves along the second direction to temporarily detach the positioning assembly 5 from the mounting frame 1, allowing the adjusting plate 4 to slide freely. After adjustment, the telescopic end of the telescopic assembly 3 is separated from the positioning assembly 5, and the positioning assembly 5 is elastically connected to return to its original position and re-adsorb on the mounting frame 1. This automated adjustment not only greatly improves production efficiency, but also reduces errors in manual operation, ensuring the accuracy of the distance of the film placing head 200 and ultimately improving the quality of the attached reflective film strip and the light energy utilization rate of the photovoltaic module.

[0073] Optionally, as shown in Figures 2-3 The mounting frame 1 includes a frame body 11 and an adsorption plate 12 mounted on the frame body 11, and the positioning assembly 5 includes a first floating plate 52, a plurality of magnets 53 and a plurality of first elastic bodies 51.

[0074] The first floating plate 52 is located between the adjusting plate 4 and the adsorption plate 12;

[0075] The end of the first floating plate 52 away from the adsorption plate 12 is elastically connected to the adjusting plate 4 through the plurality of first elastic bodies 51;

[0076] The end of the first floating plate 52 close to the adsorption plate 12 is mounted with the plurality of magnets 53, and the first floating plate 52 can be magnetically adsorbed on the adsorption plate 12 through the plurality of magnets 53;

[0077] The first elastic body 51 is configured to contract when the telescopic end of the telescopic assembly 3 pushes the first floating plate 52 along the second direction, so that the first floating plate 52 is close to the adjusting plate 4 and away from the adsorption plate 12;

[0078] The first elastic body 51 is also configured to return to its original position when the telescopic end of the telescopic assembly 3 is separated from the first floating plate 52, so that the magnets 53 on the first floating plate 52 are magnetically adsorbed on the adsorption plate 12.

[0079] Optionally, the first floating plate 52 can be made of light metal material, such as aluminum alloy or magnesium alloy. The magnets 53 can be made of high-strength permanent magnet material, such as neodymium iron boron or samarium cobalt. The shape of the magnets 53 can be cylindrical or square, which can be selected according to actual needs. The surface treatment of the magnets 53, such as nickel plating or paint spraying, can improve their corrosion resistance and prolong their service life.

[0080] The positioning assembly 5 includes the first floating plate 52, the plurality of magnets 53, and the plurality of first elastic bodies 51. This design not only improves the accuracy of the spacing adjustment, but also enhances the stability and reliability of the system. The first floating plate 52 is located between the adjustment plate 4 and the adsorption plate 12, and is stably fixed on the mounting frame 1 by magnetic adsorption between the magnets 53 and the adsorption plate 12. This magnetic adsorption method not only has strong adsorption force, but also can maintain stability during production. The first elastic body 51 contracts when the first floating plate 52 is pushed by the extension end of the extension assembly 3, causing the first floating plate 52 to move closer to the adjustment plate 4 and away from the adsorption plate 12, thereby releasing the magnetic adsorption. When the extension end of the extension assembly 3 is separated from the first floating plate 52, the first elastic body 51 returns to its original position, and the first floating plate 52 is re-adsorbed on the adsorption plate 12. The first elastic body 51 allows the first floating plate 52 to quickly reset after adjustment, improving the adjustment speed and production efficiency. In addition, this design also facilitates maintenance and replacement, reduces the failure rate and maintenance cost of the equipment, and improves the overall reliability and service life of the system.

[0081] Optionally, the first elastic body 51 includes a guide rod and a spring. The first floating plate 52 is movably connected to the adjustment plate 4 through the guide rod, and the spring is sleeved on the guide rod between the first floating plate 52 and the adjustment plate 4. The first end of the spring abuts against the first floating plate 52, and the second end of the spring abuts against the adjustment plate 4. The diameter and length of the spring are designed according to actual needs to ensure its stability and reliability during compression and rebound.

[0082] The first elastic body 51 includes a guide rod and a spring. When the first floating plate 52 is pushed by the extension end of the extension assembly 3, the spring is compressed, causing the first floating plate 52 to move closer to the adjustment plate 4 and away from the adsorption plate 12. When the extension end of the extension assembly 3 is separated from the first floating plate 52, the spring returns to its original position, and the first floating plate 52 is re-adsorbed on the adsorption plate 12. The high recovery force and uniform stress characteristics of the spring ensure that the first floating plate 52 does not deviate excessively or jam during adjustment, improving the stability and reliability of the system. In addition, the combination of the guide rod and the spring also facilitates maintenance and replacement, reduces the failure rate and maintenance cost of the equipment, and prolongs the service life of the equipment.

[0083] Optionally, continuing to refer to Figure 3The telescopic assembly 3 comprises a telescopic driving member 31 and a push rod 32, the push rod 32 is installed at the driving end of the telescopic driving member 31, the telescopic driving member 31 is configured to drive the push rod 32 to extend or retract, and the push rod 32 constitutes the telescopic end of the telescopic assembly 3.

[0084] The telescopic assembly 3 comprises a telescopic driving member 31 and a push rod 32, wherein the telescopic driving member 31 serves as the driving source of the push rod 32, and can adopt a high-precision and high-response-speed driving device such as a pneumatic cylinder or an electric cylinder, so as to ensure the accurate telescoping of the push rod 32 in the second direction. The push rod 32 serves as the telescopic end of the telescopic assembly 3, and its extension and retraction directly affect the adsorption and release of the positioning assembly 5. When the push rod 32 extends, it pushes the positioning assembly 5 in the second direction, so that the positioning assembly 5 temporarily separates from the mounting rack 1, thereby allowing the adjustment plate 4 to slide freely; when the push rod 32 retracts, it separates from the positioning assembly 5, and the positioning assembly 5 is reset by the elastic connection and rebounds, and is re-adsorbed on the mounting rack 1. Such a design not only simplifies the mechanism, but also improves the adjustment speed and accuracy. The high reliability of the telescopic driving member 31 ensures that each adjustment can be accurately completed, and reduces the equipment failure rate.

[0085] Optionally, continuing to refer to Figure 3 Each of the positioning assemblies 5 is provided with a first insertion hole, the diameter of the leading end of the push rod 32 is less than or equal to the diameter of the first insertion hole; the leading end of the push rod 32 can pass through or exit the first insertion hole along with the extension or retraction of the push rod 32.

[0086] The diameter of the trailing end of the push rod 32 is greater than the diameter of the first insertion hole, and the trailing end of the push rod 32 can abut against the outer edge of the first insertion hole along with the extension of the push rod 32, thereby pushing the positioning assembly 5 away from the mounting rack 1.

[0087] Optionally, the first insertion hole is provided on the first floating plate 52; each of the adjustment plates 4 is provided with a second insertion hole 41, and the diameter of the leading end of the push rod 32 is less than or equal to the diameter of the second insertion hole 41.

[0088] The second insertion hole 41 on the adjustment plate 4 and the first insertion hole on the positioning assembly 5 corresponding to the adjustment plate 4 are located at the same height, so that the leading end of the push rod 32 can pass through the second insertion hole 41 and the first insertion hole at the same time.

[0089] The design of the first socket on the positioning assembly 5 cooperating with the leading end of the push rod 32 not only improves the accuracy of the spacing adjustment, but also enhances the reliability and maintainability of the system. The diameter of the leading end of the push rod 32 is less than or equal to the hole diameter of the first socket, so that the push rod 32 can smoothly pass through the first socket and achieve precise positioning. When the push rod 32 is extended, its leading end passes through the first socket, and then the trailing end of the push rod 32 abuts against the outer edge of the first socket, thereby pushing the positioning assembly 5 away from the mounting rack 1. When the push rod 32 is retracted, its leading end exits the first socket, and the positioning assembly 5 returns to its original position and re-adsorbs on the mounting rack 1. This socket structure not only improves the stability and reliability of the adjustment process, but also simplifies the maintenance and replacement process. The structural design of the push rod 32 makes the influence on the positioning assembly 5 more uniform and stable during extension and retraction, avoiding the problem of adjustment plate 4 deviation or jamming caused by uneven local stress. In addition, the size design of the leading end and trailing end of the push rod 32 enables it to cooperate more effectively with the positioning assembly 5, ensuring efficient and accurate adjustment.

[0090] Optionally, the positioning assembly 5 includes a second floating plate, a plurality of suction cups, and a plurality of second elastic bodies, wherein:

[0091] The second floating plate is located between the adjustment plate 4 and the mounting rack 1;

[0092] One end of the second floating plate away from the mounting rack 1 is elastically connected to the adjustment plate 4 through a plurality of second elastic bodies;

[0093] The second floating plate is installed with a plurality of suction cups at one end close to the mounting rack 1, and the second floating plate can be adsorbed on the mounting rack 1 through the plurality of suction cups;

[0094] The second elastic body is configured to contract when the extension end of the extension assembly 3 pushes the second floating plate in the second direction, so that the second floating plate is close to the adjustment plate 4 and away from the mounting rack 1;

[0095] The second elastic body is also configured to return to its original position when the extension end of the extension assembly 3 separates from the second floating plate, so that the suction cups on the second floating plate adsorb on the mounting rack 1.

[0096] Optionally, the suction cups are made of high-vacuum and wear-resistant materials such as silicone or rubber. The diameter and thickness of the suction cups are designed according to actual needs to ensure their stability and reliability during adsorption. The inner wall of the suction cup is provided with a plurality of grooves to increase its adsorption force and air leakage prevention performance. The outer wall of the suction cup is provided with a guide slope to facilitate its cooperation with the adsorption surface on the mounting rack 1.

[0097] The positioning assembly 5 includes a second floating plate, a plurality of suction cups, and a plurality of second elastic bodies. This design not only improves the accuracy of the spacing adjustment, but also enhances the stability and versatility of the system. The second floating plate is located between the adjusting plate 4 and the mounting rack 1. Through the suction force between the suction cups and the mounting rack 1, the positioning assembly 5 is stably fixed on the mounting rack 1. The use of suction cups makes the suction force strong and uniform, so that the system can remain stable even on mounting racks 1 with different surface characteristics, improving the versatility and adaptability of the system. The second elastic body contracts when the second floating plate is pushed by the telescopic end of the telescopic assembly 3, causing the second floating plate to move closer to the adjusting plate 4 and away from the mounting rack 1, thereby releasing the suction. When the telescopic end of the telescopic assembly 3 is separated from the second floating plate, the second elastic body returns to its original position, and the second floating plate is reattached to the mounting rack 1 by the suction cups. This elastic design ensures smooth adjustment each time, reducing equipment failures caused by sudden release or reset. Overall, this design not only improves the accuracy of the adjustment, but also enhances the stability and versatility of the system, making it suitable for a variety of production environments.

[0098] Optionally, referring back to Figure 3 , the spacing adjustment mechanism further includes a photoelectric sensor 6 and a plurality of sensing pieces 7;

The telescopic end of the telescopic assembly 3 is used to push the corresponding positioning assembly 5 after the corresponding sensing piece 7 is sensed.

[0101] The photoelectric sensor 6 is installed on the driving end of the horizontal movement driving assembly 2, and the sensing pieces 7 are installed one by one on the adjusting plate 4. This design not only improves the accuracy of the spacing adjustment, but also enhances the degree of automation and reliability of the system. When the horizontal movement driving assembly 2 drives the photoelectric sensor 6 to move, the photoelectric sensor 6 can detect the corresponding sensing piece 7, thereby determining the position of the adjusting plate 4. This position detection method not only has high accuracy, but also has fast response speed, reducing manual intervention during the adjustment process. The telescopic end of the telescopic assembly 3 pushes the corresponding positioning assembly 5 after the corresponding sensing piece 7 is sensed, realizing the spacing adjustment. The high sensitivity and fast response characteristics of the photoelectric sensor 6 make the adjustment process more rapid and smooth, improving production efficiency.

This design not only improves the compactness and stability of the system, but also ensures the smooth progress of the distance adjustment process. The avoidance space allows the telescopic end of the telescopic assembly 3 to extend through the avoidance space and directly push the positioning assembly 5 away from the mounting frame 1, and when it is retracted, it separates from the positioning assembly 5, without affecting the reset of the positioning assembly 5. The structure of the mounting frame 1 on the upper and lower sides of the avoidance space ensures the adsorption area of the positioning assembly 5, improving the stability and reliability of adsorption. Overall, this arrangement not only simplifies the system design, but also improves the performance and applicability of the distance adjustment mechanism, making it more suitable for automated production lines.

The modulus and pressure angle of the gear are selected according to actual needs to ensure its transmission efficiency and stability. The rack 22 is made of high-strength and wear-resistant material such as steel or stainless steel. The rack 22 is designed to match the gear teeth to ensure the precision of its engagement. The surface treatment of the rack 22 (such as chrome plating or paint spraying) can improve its wear resistance and rust resistance, prolonging its service life.

[0111] The transverse drive assembly 2 includes a motor 21, a gear, a rack 22 and a moving plate 23. This design not only improves the accuracy of the pitch adjustment, but also enhances the reliability and automation of the system. The motor 21 serves as the power source, and its high precision and programmability ensure accurate control of the transverse drive assembly 2. The combination of the gear and the rack 22 converts the rotational motion of the motor 21 into linear motion, allowing the moving plate 23 to slide in the first direction. The moving plate 23 serves as the carrier of the telescopic assembly 3, and through its sliding, the telescopic assembly 3 can accurately reach the position of the adjustment plate 4 to be adjusted. This structure not only simplifies the system design, but also ensures the stability and accuracy of the entire adjustment process. The high precision transmission characteristics of the gear and the rack 22 allow the movement position of each adjustment plate 4 to be accurately controlled, reducing the problem of film strip attachment caused by inaccurate adjustment plate 4 position.

The use of the pitch adjustment mechanism 100 allows the pitch of the film releasing heads 200 to be quickly and accurately adjusted, adapting to different sizes of back plates. The plurality of film releasing heads 200 can simultaneously release multiple reflective film strips, improving the film releasing speed and consistency. This design of the film releasing device not only applies to large-scale production, but also flexibly meets the demand for back plates of different sizes, with high market competitiveness and application prospect.
