Technical Field
[0001] This application belongs to the technical field of photovoltaic cell production equipment, and in particular relates to a cell string printing equipment. Background Technology
[0002] In the production process of photovoltaic cells, after the cell strings are welded, adhesive is applied to the surface of the cells using an adhesive printing device to ensure that the solder ribbons and cells are stably fixed together. Existing adhesive printing equipment typically uses a first transport mechanism to move the welded cell strings to the adhesive printing table, where the adhesive printing mechanism applies adhesive to the strings. After printing, a second transport mechanism removes the printed cell strings. While this method allows for automated printing, the first transport mechanism cannot place new cell strings on the printing table until the second transport mechanism removes them, resulting in low production efficiency. Utility Model Content
[0003] The purpose of this application is to provide a battery string printing device to solve the problem of low production efficiency in existing printing devices.

[0006] The battery string printing equipment is arranged in sequence along the first horizontal direction with a material picking station, a printing station and a material unloading station. The printing device is set at the printing station, and the first conveying mechanism and the second conveying mechanism are installed on the base.
[0007] The first conveying mechanism is used to drive the first printing table to slide back and forth along the first horizontal direction. The first conveying mechanism is configured to drive the first printing table to the material pick-up station to receive the battery string to be printed. The first conveying mechanism is also configured to drive the first printing table to the printing station so that the printing device can print the battery string on the first printing table. The first conveying mechanism is also configured to drive the first printing table to the unloading station to wait for the printed battery string to be taken away.
[0008] The second conveying mechanism is used to drive the second printing table to slide back and forth along the first horizontal direction. The second conveying mechanism is configured to drive the second printing table to the material pick-up station to receive the battery string to be printed. The second conveying mechanism is also configured to drive the second printing table to the printing station so that the printing device can print the battery string on the second printing table. The second conveying mechanism is also configured to drive the second printing table to the unloading station to wait for the printed battery string to be taken away.
[0009] The battery string printing equipment proposed in this application is equipped with a first printing station and a second printing station. When the first printing station receives the battery string to be printed at the material pick-up station and moves to the printing station to perform printing, the second printing station moves to the material pick-up station to receive the battery string to be printed. After the battery string printing is completed, the first printing station moves from the printing station to the unloading station, while the second printing station moves from the material pick-up station to the printing station to print the battery string on the second printing station. After the external conveying mechanism picks up the printed battery string from the first printing station at the unloading station, the first printing station moves from the unloading station to the material pick-up station to receive the battery string to be printed. This process is repeated, realizing continuous operation of the battery string printing equipment and improving production efficiency.
[0010] Optionally, the first conveying mechanism includes a first sliding drive and a first sliding member. The first sliding member is slidably mounted on the base along a first horizontal direction. The drive end of the first sliding drive is connected to the first sliding member. The first sliding drive is configured to drive the first sliding member to slide along the first horizontal direction. The first printing table is mounted on the first sliding member.
[0011] The second conveying mechanism includes a second sliding drive and a second sliding member. The second sliding member is slidably mounted on the base along a first horizontal direction. The drive end of the second sliding drive is connected to the second sliding member. The second sliding drive is configured to drive the second sliding member to slide along the first horizontal direction. The second printing table is mounted on the second sliding member.
[0012] The first sliding member is driven by the first sliding drive to slide along the first horizontal direction, thereby enabling the first printing table to move between the material picking station, the printing station, and the unloading station; the second sliding member is driven by the second sliding drive to slide along the first horizontal direction, thereby enabling the second printing table to move between the material picking station, the printing station, and the unloading station, so that the first and second printing tables slide side by side on the same horizontal plane without interfering with each other; a first conveying mechanism and a second conveying mechanism with simple structure and easy to implement are provided.
[0013] Optionally, the movement paths of the first printing table and the second printing table in the first horizontal direction at least partially overlap.

[0015] When the second printing table needs to pass over the first printing table, the first lifting drive unit drives the first printing table to descend so that the upper surface of the first printing table is lower than the bottom surface of the second printing table.
[0016] By setting a first lifting drive component and mounting the first printing table movably on the first sliding component, the lifting and lowering of the first printing table is achieved. Then, when the second printing table needs to pass over the first printing table, the first printing table is lowered to below the second printing table, making it easier for the second printing table to pass over the first printing table. This provides a first conveying mechanism that can drive the first printing table to slide and lift along a first horizontal direction, so as to meet the application scenario where the movement paths of the first and second printing tables in the first horizontal direction at least partially overlap. The structure is simple and the operation is stable and reliable.

[0018] When the second printing table needs to pass over the first printing table, the first lifting drive drives the first printing table to descend, and the second lifting drive drives the second printing table to rise, so that the upper surface of the first printing table is lower than the bottom surface of the second printing table.
[0019] By setting a second lifting drive and mounting the second printing table movably on the second sliding member, the lifting and lowering of the second printing table is achieved. When the second printing table needs to pass over the first printing table, the first printing table descends and the second printing table rises, so that the first printing table descends to below the second printing table, making it easier for the second printing table to pass over the first printing table. This provides a second conveying mechanism that can drive the second printing table to slide and rise and fall along the first horizontal direction, realizing rapid misalignment of the first and second printing tables in the height direction, resulting in high work efficiency.
[0020] Optionally, the first sliding member and the second sliding member are located on both sides of the base along the first horizontal direction.
[0021] By setting the first sliding member and the second sliding member to be located on both sides of the base along the first horizontal direction, the first sliding member and the second sliding member can avoid each other, thus preventing interference when the first sliding member and the second sliding member slide along the first horizontal direction.
[0022] Optionally, the first and second printing tables have the same structure. The first printing table includes a load-bearing component, a lifting base, and several L-shaped support rods, wherein:

The top ends of the two first support plates are respectively fixedly connected to the two ends of the first carrier platform along the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction on the horizontal plane.
[0027] The second printing table includes a second carrier table and two second support plates. The second carrier table is configured to carry the battery string. The two second support plates are spaced apart on the second sliding member along the second horizontal direction. The top ends of the two second support plates are respectively fixedly connected to the two ends of the second carrier table along the second horizontal direction.
[0028] Two second support plates and a second carrier platform form a passageway for the first printing table and the first sliding component to pass under the second carrier platform.
[0029] By cooperating with the first bearing platform and the two first support plates, and with the second bearing platform and the two second support plates, stable and reliable support is achieved at both ends of the first and second bearing platforms in the second horizontal direction.

[0032] By setting an adsorption component on the first and second printing tables, the battery string is adsorbed and fixed on the corresponding first or second printing table, ensuring that the battery string will not shift during transportation. The adsorption of the battery string is achieved through the cooperation of the adsorption chamber, multiple adsorption holes and the air extraction device, providing an adsorption component with a simple structure and easy implementation.

The drive motor drives the driving pulley to rotate, so as to drive the transmission belt to rotate through the cooperation of the driven pulley, and then drive the corresponding first sliding member or second sliding member to slide along the first horizontal direction through the transmission belt.
[0036] The drive motors of the first sliding drive and the second sliding drive are located at the same end of the base along the first horizontal direction, and the rotation axes of the drive pulley of the first sliding drive and the drive pulley of the second sliding drive are collinear.
[0037] By cooperating with the drive motor, the driving pulley, the driven pulley, and the transmission belt, the corresponding first or second sliding component is driven to slide along the first horizontal direction. This provides a first and second sliding drive component with high driving efficiency, high driving accuracy, low noise, and easy maintenance.

The squeegee drive drives the squeegee to descend and press against the screen on the base before sliding to scrape the glue on the screen into the mesh of the screen. The glue flows through the mesh to the battery cells of the battery string on the first printing table or the second printing table.
[0040] Auxiliary support members are respectively provided at both ends of the first printing table or the second printing table along the first horizontal direction. After the third lifting drive member drives the lifting seat to descend, the base of the screen printing assembly abuts against the auxiliary support members of the first printing table or the second printing table located at the printing station along the first horizontal direction.
[0041] The lifting and lowering of the screen printing assembly is achieved through the cooperation of the third lifting drive and the lifting base; the glue on the screen is scraped into the mesh of the screen through the cooperation of the squeegee drive and the squeegee, so as to apply glue to the battery string of the first or second printing table, providing a simple and stable printing device; at the same time, auxiliary support members are set at both ends of the first or second printing table, so as to achieve stable and reliable support for the base of the screen printing assembly at both ends along the first horizontal direction during printing.

[0061] 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.
[0062] In the production process of photovoltaic cells, after the cell strings are welded, adhesive is applied to the surface of the cells using an adhesive printing device to ensure that the solder ribbons and cells are stably fixed together. Existing adhesive printing equipment typically uses a first transport mechanism to move the welded cell strings to the adhesive printing table, where the adhesive printing mechanism applies adhesive to the strings. After printing, a second transport mechanism removes the printed cell strings. While this method allows for automated printing, the first transport mechanism cannot place new cell strings on the printing table until the second transport mechanism removes them, resulting in low production efficiency.
[0063] Therefore, this application proposes a battery string printing apparatus; please refer to [link to relevant documentation]. Figure 1 , Figure 2 and Figure 4 As shown, the battery string printing equipment proposed in this application includes a base 10, a first conveying mechanism 20, a second conveying mechanism 21, a first printing table 30, a second printing table 31, and a printing device 40. The battery string printing equipment is installed along a first horizontal direction ( Figure 1The base 10 is equipped with a material picking station 11, an adhesive printing station 12, and a material unloading station 13 arranged sequentially in the X direction. An adhesive printing device 40 is located at the adhesive printing station 12. A first conveying mechanism 20 and a second conveying mechanism 21 are mounted on the base 10. The first conveying mechanism 20 drives the first adhesive printing table 30 to reciprocate along the first horizontal direction. The first conveying mechanism 20 is configured to drive the first adhesive printing table 30 to the material picking station 11 to receive the battery string 50 to be printed. The first conveying mechanism 20 is also configured to drive the first adhesive printing table 30 to the adhesive printing station 12 so that the adhesive printing device 40 can print adhesive on the battery string 50 on the first adhesive printing table 30. It is also configured to drive the first printing table 30 to the unloading station 13 to wait for the printed battery string 50 to be taken away; the second conveying mechanism 21 is used to drive the second printing table 31 to slide back and forth along the first horizontal direction. The second conveying mechanism 21 is configured to drive the second printing table 31 to the unloading station 11 to receive the battery string 50 to be printed. The second conveying mechanism 21 is also configured to drive the second printing table 31 to the printing station 12 so that the printing device 40 can print the battery string 50 on the second printing table 31. The second conveying mechanism 21 is also configured to drive the second printing table 31 to the unloading station 13 to wait for the printed battery string 50 to be taken away.
[0064] The battery string printing equipment proposed in this application is configured with a first printing station 30 and a second printing station 31. When the first printing station 30 receives the battery string 50 to be printed at the material pick-up station 11 and moves it to the printing station 12 for printing, the second printing station 31 moves to the material pick-up station 11 to receive the battery string 50 to be printed. After the battery string 50 is printed, the first printing station 30 moves from the printing station 12 to the unloading station 13. At the same time, the second printing station 31 moves from the material pick-up station 11 to the printing station 12 to print the battery string 50 on the second printing station 31. After the external conveying mechanism picks up the printed battery string 50 from the first printing station 30 at the unloading station 13, the first printing station 30 moves from the unloading station 13 to the material pick-up station 11 to receive the battery string 50 to be printed. This process is repeated to achieve continuous operation of the battery string printing equipment and improve production efficiency.
[0065] In one embodiment, the first conveying mechanism 20 includes a first sliding drive 22 and a first sliding member 23. The first sliding member 23 is slidably mounted on the base 10 along a first horizontal direction. The drive end of the first sliding drive 22 is connected to the first sliding member 23. The first sliding drive 22 is configured to drive the first sliding member 23 to slide along the first horizontal direction. The first printing table 30 is mounted on the first sliding member 23. The second conveying mechanism 21 includes a second sliding drive 24 and a second sliding member 25. The second sliding member 25 is slidably mounted on the base 10 along a first horizontal direction. The drive end of the second sliding drive 24 is connected to the second sliding member 25. The second sliding drive 24 is configured to drive the second sliding member 25 to slide along the first horizontal direction. The second printing table 31 is mounted on the second sliding member 25.
[0066] As can be seen, by driving the first sliding member 23 to slide along the first horizontal direction through the first sliding drive member 22, the first printing table 30 is moved between the material picking station 11, the printing station 12, and the unloading station 13. By driving the second sliding member 25 to slide along the first horizontal direction through the second sliding drive member 24, the second printing table 31 is moved between the material picking station 11, the printing station 12, and the unloading station 13, so that the first printing table 30 and the second printing table 31 slide side by side on the same horizontal plane without interfering with each other. This provides a first conveying mechanism 20 and a second conveying mechanism 21 with a simple structure that is easy to implement.
[0067] In one implementation, the movement paths of the first printing table 30 and the second printing table 31 in the first horizontal direction at least partially overlap; the first conveying mechanism 20 further includes a first lifting drive 26, the first printing table 30 is movably mounted on the first sliding member 23, the first lifting drive 26 is mounted on the first sliding member 23, the driving end of the first lifting drive 26 is connected to the first printing table 30, and the first lifting drive 26 is configured to drive the first printing table 30 to rise and fall; when the second printing table 31 needs to pass over the first printing table 30, the first lifting drive 26 drives the first printing table 30 to fall so that the upper surface of the first printing table 30 is lower than the bottom surface of the second printing table 31.
[0068] Specifically, the first lifting drive component 26 is a cylinder.
[0069] As can be seen, by setting the first lifting drive component 26 and mounting the first printing table 30 movably on the first sliding component 23, the lifting and lowering of the first printing table 30 is achieved. Then, when the second printing table 31 needs to pass over the first printing table 30, the first printing table 30 is lowered to below the second printing table 31, so that the second printing table 31 can pass over the first printing table 30. This provides a first conveying mechanism 20 that can drive the first printing table 30 to slide and lift along the first horizontal direction, so as to meet the application scenario where the movement paths of the first printing table 30 and the second printing table 31 in the first horizontal direction are at least partially overlapped. The structure is simple and the operation is stable and reliable.
[0070] In one embodiment, the second conveying mechanism 21 further includes a second lifting drive 27. The second printing table 31 is movably mounted on the second sliding member 25. The second lifting drive 27 is mounted on the second sliding member 25. The driving end of the second lifting drive 27 is connected to the second printing table 31. The second lifting drive 27 is configured to drive the second printing table 31 to rise and fall. When the second printing table 31 needs to pass over the first printing table 30, the first lifting drive 26 drives the first printing table 30 to fall, and the second lifting drive 27 drives the second printing table 31 to rise, so that the upper surface of the first printing table 30 is lower than the bottom surface of the second printing table 31.
[0071] Specifically, the second lifting drive component 27 is a cylinder.
[0072] As can be seen, by setting the second lifting drive component 27 and mounting the second printing table 31 movably on the second sliding component 25, the second printing table 31 is driven to rise and fall. When the second printing table 31 needs to pass over the first printing table 30, the first printing table 30 descends and the second printing table 31 rises, so that the first printing table 30 descends as a whole to below the second printing table 31, making it easier for the second printing table 31 to pass over the first printing table 30. This provides a second conveying mechanism 21 that can drive the second printing table 31 to slide and rise and fall along the first horizontal direction, realizing the rapid misalignment of the first printing table 30 and the second printing table 31 in the height direction, resulting in high working efficiency.
[0073] In one embodiment, the first sliding member 23 and the second sliding member 25 are located on both sides of the base 10 along the first horizontal direction.
[0074] It can be seen that by setting the first sliding member 23 and the second sliding member 25 to be located on both sides of the base 10 along the first horizontal direction, the first sliding member 23 and the second sliding member 25 can avoid each other, thus preventing interference when the first sliding member 23 and the second sliding member 25 slide along the first horizontal direction.

The supporting component 300 is configured to support the battery string 50. Several support rods 302 are installed at intervals along a first horizontal direction on the lifting seat 301. The first end of the support rod 302 is fixedly installed on the lifting seat 301, and the second end of the support rod 302 is fixedly installed on the supporting component 300. The lifting seat 301 is movably mounted on the first sliding member 23. The driving end of the first lifting drive member 26 is connected to the corresponding lifting seat 301. The first lifting drive member 26 is configured to drive the lifting seat 301 to move up and down.
[0076] Specifically, the lifting seat 301 has multiple weight-reducing holes.
[0077] As can be seen, by using several L-shaped support rods 302 to support the load-bearing component 300, a first printing table 30 and a second printing table 31 with a single-sided cantilever support structure are provided. Under the premise of ensuring stable and reliable support, it has the advantages of simple structure, easy implementation and space saving.

The drive end of the third lifting drive 43 is connected to the lifting seat 42. The third lifting drive 43 is configured to drive the lifting seat 42 to descend, so that the screen printing assembly 44 approaches the battery string 50 on the first printing table 30 or the second printing table 31. The screen printing assembly 44 is mounted on the lifting seat 42 and includes a base 440, a screen 441, a squeegee drive 442, and a squeegee. The base 440 is mounted on the lifting seat 42, and the screen 441 is detachably mounted on the base 440. The squeegee is positioned on... Above the base 440, the drive end of the squeegee drive 442 is connected to the squeegee. The squeegee drive 442 is configured to drive the squeegee to rise, fall, and slide. The squeegee drive 442 drives the squeegee to fall and press against the screen 441 on the base 440, and then slides to scrape the glue on the screen 441 into the mesh of the screen 441. The glue flows through the mesh to the battery cells of the battery string 50 of the first printing table 30 or the second printing table 31. The first printing table 30 or the second printing table 31 is provided with auxiliary support members 32 at both ends along the first horizontal direction. After the third lifting drive 43 drives the lifting seat 42 to fall, the base 10 of the screen printing assembly 44 abuts against the auxiliary support members 32 of the first printing table 30 or the second printing table 31 located at the printing station 12 along the first horizontal direction.
[0085] Specifically, the third lifting drive component 43 adopts a ball screw type linear module, and the scraper drive component 442 includes at least a lifting module and a translation module, which drive the scraper to move horizontally and lift vertically through the cooperation of the lifting module and the translation module.
[0086] As can be seen, the lifting and lowering of the screen printing assembly 44 is achieved through the cooperation of the third lifting drive 43 and the lifting base 42; the cooperation of the squeegee drive 442 and the squeegee is achieved through the scraping of glue on the screen 441 into the mesh of the screen 441 to apply glue to the battery string 50 of the first printing table 30 or the second printing table 31, providing a simple structure and stable and reliable printing device 40; at the same time, auxiliary support members 32 are set at both ends of the first printing table 30 or the second printing table 31 to achieve stable and reliable support for both ends of the base 10 of the screen printing assembly 44 along the first horizontal direction during glue printing.
[0087] In one embodiment, the printing apparatus 40 further includes a first detection component 45, a second detection component 46, and a photocuring component 47.

The first detection component 45 is configured to detect the position information of the solder ribbons of the battery string 50 on the first printing table 30 or the second printing table 31 to determine whether the position of the solder ribbons is accurate and to send the position information of the accurately positioned solder ribbons to the screen printing component 44, thereby controlling the printing path of the screen printing component 44. The second detection component 46 is disposed between the printing station 12 and the unloading station 13. The second detection component 46 is configured to detect the printing surface of the battery string 50 on the first printing table 30 or the second printing table 31 to determine whether the battery string 50 is qualified after printing. The photocuring component 47 is disposed after the second detection component 46 and is configured to perform photocuring on the adhesive on the qualified battery string 50.
[0088] Specifically, both the first detection component 45 and the second detection component 46 use industrial cameras, and the photocuring component 47 uses a UV curing machine. By irradiating with a UV (ultraviolet) light source, the photosensitizer in the adhesive on the battery string 50 undergoes a chemical reaction, causing the adhesive to quickly transform from a liquid state to a solid state.
[0089] As can be seen, by setting the first detection component 45, the position of the solder ribbon of the battery string 50 is automatically detected before the adhesive is printed, and the printing path is controlled in conjunction with the screen printing component 44; by setting the second detection component 46, the battery string 50 is automatically detected after the adhesive is printed, so as to ensure the printing quality of the battery string; by setting the photocuring component 47, the adhesive on the battery string 50 is cured, so that the adhesive stably connects the solder ribbon and the battery cell.
[0090] The general printing process of the printing apparatus 40 proposed in this application embodiment is as follows:
[0091] S1, the first printing table 30 or the second printing table 31 is moved to the first detection component 45, and the first detection component 45 performs photo detection on the battery string 50 on the first printing table 30 or the second printing table 31 to obtain the position information of the solder strip of the battery string 50 and send the position information of the accurately positioned solder strip to the control module.
[0092] S2, the first printing table 30 or the second printing table 31 moves to the printing station 12, the third lifting drive 44 drives the lifting seat 42 to descend to a preset height, the squeegee drive 442 drives the squeegee to rise and slide to scrape the glue on the screen 441 into the mesh of the screen 441, the glue flows through the mesh to the battery cells of the battery string 50 of the first printing table 30 or the second printing table 31, and the third lifting drive 44 drives the lifting seat 42 to return to its original position;
[0093] S3, the first printing station 30 or the second printing station 31 is moved to the second detection component 46, and the second detection component 46 takes pictures of the printing surface of the battery string 50 on the first printing station 30 or the second printing station 31 to determine whether the battery string 50 is qualified after printing and sends the detection result to the control module.
[0094] S4, the first printing table 30 or the second printing table 31 is moved to the photocuring component 47, and the photocuring component 47 performs photocuring on the adhesive on the qualified battery string 50.
[0095] The general workflow of the battery string printing equipment proposed in this application is as follows:
[0096] S1, In the initial state, the first conveying mechanism 20 conveys the first printing table 30 to the material picking station 11, and receives the battery string to be printed by the first handling mechanism 70 through the first printing table 30.
[0097] S2, the first conveying mechanism 20 conveys the first printing table 30 to the printing station 12, and the printing device 40 prints the battery string 50 on the first printing table 30. After the first printing table 30 leaves the material picking station 11, the second conveying mechanism 21 conveys the second printing table 31 to the material picking station 11, so as to receive the next battery string to be printed by the first conveying mechanism 70 through the second printing table 31.
[0098] S3, the first conveying mechanism 20 conveys the first printing table 30 to the unloading station 13, waiting for the second handling mechanism to remove the battery string 50 after printing on the first printing table 30. After the first printing table 30 leaves the printing station 12, the second conveying mechanism 21 conveys the second printing table 31 to the printing station 12, and prints the battery string 50 on the second printing table 31 through the printing device 40.
[0099] S4, after the second conveying mechanism removes the battery string 50 printed by the first printing table 30, the first conveying mechanism 20 conveys the first printing table 30 to the material picking station 11. After the first printing table 30 leaves the unloading station 13, the second conveying mechanism 21 conveys the second printing table 31 to the unloading station 13, waiting for the second conveying mechanism to remove the battery string 50 printed by the second printing table 31.
[0100] S5. Repeat steps S1-S4 above to achieve continuous printing of adhesive on the battery string.
[0101] Additionally, it should be noted that in this field, battery strings 50 to be printed are generally produced using a stringer. The first conveying mechanism 70 picks up the battery strings 50 to be printed from the discharge end of the stringer. Different stringer manufacturing processes can result in the battery strings 50 being placed with the solder strip facing down or up. The printing equipment needs to print the adhesive on the solder strip side of the battery strings 50. Therefore, if the solder strip side of the battery string 50 is facing up, the first conveying mechanism 70 can directly pick it up from the discharge end of the stringer. If the solder strip side of the battery string 50 is facing down, a flipping mechanism is required to flip the battery strings 50 from the discharge end of the stringer, and then the first conveying mechanism 70 picks up the flipped battery strings 50. Alternatively, the first conveying mechanism 70 can pick up the battery string 50 with the solder strip facing down and place it on the flipping mechanism. The flipping mechanism flips the battery string 50 and places it on the first printing table 30 or the second printing table 31 located at the material picking station 11, ensuring that the battery string 50 is ultimately placed on the first printing table 30 or the second printing table 31 with the solder strip facing up.
[0102] The battery string printing equipment proposed in this application has the following advantages:
[0103] 1) It enables continuous operation of the battery string printing equipment, thereby improving production efficiency;
[0104] 2) The first and second conveying mechanisms adopt three different design forms to meet the requirements of different application scenarios;
[0105] 3) Both the first and second printing tables are equipped with adsorption components to ensure that the battery string does not shift during the transportation process, thereby improving the quality of printing.
[0106] 4) The overall structure is compact, occupies little space, and has a reasonable layout.
[0107] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
