Description

Technical Field

[0001] This invention relates to the field of fully automated manufacturing technology of integrated terminal blocks, and particularly to a fully automated terminal block forming equipment and forming method. Background Technology

[0002] Terminal blocks are important components for connecting batteries to external circuits, serving to connect external devices and conduct current. Currently, the terminals of batteries are composed of copper cores and lead bases, which are then sealed with adhesive base glue and colored glue after being matched with the terminal slots in the middle cover. Therefore, most existing terminal blocks are made of copper or aluminum.

[0003] Terminal blocks typically consist of connecting pieces, terminals, and positioning posts. They are classified as either integrated or separate. Chinese patent CN201711022559.4 discloses a weld-free integrated terminal block and its processing technology and equipment. This design addresses the technical problems of existing welded products, which suffer from poor strength, conductivity, and lifespan, as well as inefficient manufacturing processes and low automation. The copper terminals of this type of terminal block have copper inserts and copper pieces integrally formed. The key feature is that the copper terminal is made from irregularly shaped copper material, cut into irregularly shaped copper blocks using an automatic cutting machine. These blocks are then processed by an automatic CNC machine to form large and small cylindrical copper inserts on both sides of one end. Simultaneously, the large cylindrical copper inserts pass through screw holes formed by the automatic CNC machine. Finally, the copper inserts of the copper terminal are formed by stamping and milling. Thus, the entire copper terminal is integrally formed from an irregularly shaped copper block, eliminating the need for welding and die casting of similar products. It is particularly suitable for use as the positive and negative terminals of lead-acid batteries.

[0004] However, in the above technical solutions, the processing of the wiring terminals requires transfer and switching, and the processing reference changes, resulting in low processing accuracy, cumbersome processing steps, and low degree of automation. Summary of the Invention

[0005] To address the above problems, this invention provides a fully automatic terminal block forming equipment and method. By utilizing the cooperation of a cutting saw group, a positioning turntable group, a first milling cutter group, a drilling group, a tapping group, a stamping group, a chamfering group, a second milling cutter group, and an ejector pin group, the fully automatic integrated forming process of the terminal block is achieved. The terminal block does not require changing the processing reference during the processing, has high processing accuracy, simplified processing steps, and requires no manual intervention.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated forming equipment for terminal blocks is disclosed, which processes one-piece terminal blocks. The terminal block includes a terminal piece, a terminal post, and a positioning post. The terminal piece is oblong in shape, and the terminal post and the positioning post are respectively disposed on both sides of the terminal piece. The automated forming equipment includes: Cutting saw assembly, positioning turntable assembly, first milling cutter assembly, drilling assembly, tapping assembly, stamping assembly, chamfering assembly, second milling cutter assembly, and ejector pin assembly; The cutting saw cuts the bar material into segments of a fixed length. The positioning turntable assembly is rotatably arranged, and the positioning turntable assembly is provided with a number of positioning slots. The positioning slots are configured to mimic the shape of the segment material, and the positioning slots are used to position the segment material. The first milling cutter group, drilling group, tapping group, stamping group, chamfering group, second milling cutter group, and ejector pin group are arranged sequentially along the circumference of the positioning turntable group, and the first milling cutter group, drilling group, tapping group, stamping group, chamfering group, second milling cutter group, and ejector pin group each correspond to a positioning groove of a group; The first milling cutter group processes the terminal block, the drilling group processes the terminal hole on the terminal block and the positioning hole on the terminal piece, the tapping group processes the thread in the terminal hole, the stamping group stamps the stamp on the terminal block, the chamfering group chamfers the positioning hole and the terminal hole, the second milling cutter group processes the positioning post, and the ejector pin group ejects the processed terminal block from the positioning groove.

[0007] As an improvement, the cutting saw assembly includes a first saw blade, a second saw blade, and a third saw blade that rotate synchronously and are arranged in parallel. The first saw blade cuts the bar material into segments, and the second and third saw blades respectively form a first cutting groove and a second cutting groove on the segments.

[0008] As an improvement, the distance between the first cutting groove and the second cutting groove is equal to the thickness of the connector piece.

[0009] As an improvement, the positioning turntable assembly includes a turntable, a connecting block, and a clamping block; The turntable is self-rotating, and several sets of connecting blocks are provided. The connecting blocks are equidistantly arranged along the circumference of the turntable. The clamping blocks are arranged in one-to-one correspondence with the connecting blocks, and the clamping blocks are provided with positioning grooves.

[0010] As an improvement, the material segment is slidably adjusted within the corresponding positioning groove.

[0011] As an improvement, both the first and second milling cutter groups include milling cutters and mandrels, with the milling cutters and mandrels respectively located on both sides of the corresponding material section, and each milling cutter having a forming groove at its center.

[0012] As an improvement, the drilling group is provided in two sets, each corresponding to a forming groove in one set during operation. Each drilling group includes a drill bit and a positioning head respectively located on both sides of the corresponding segment. The drill bit rotates to form the wiring hole or the positioning hole, and the positioning head abuts against the segment to block the segment.

[0013] As an improvement, the tapping assembly includes a tap head and a blocking head respectively disposed on both sides of the corresponding section of material. The tap head is rotatably disposed, and the blocking head blocks the section of material.

[0014] As an improvement, the stamping assembly includes a stamping head and a limiting head respectively disposed on both sides of the corresponding segment material, the stamping head being telescopically oriented, and the limiting head blocking the segment material.

[0015] Furthermore, the present invention also provides a molding method based on the fully automatic molding equipment for terminal blocks described in any one of the above claims, comprising the following steps: Step a: Fixed-length cutting. Long strips of bar material are cut into fixed-length segments using a cutting saw set. Step b: Terminal forming. A fixed-length section of material is driven by the clamping of the positioning turntable group to rotate to the first milling cutter group, where the first milling cutter group processes and forms a cylindrical terminal. Step c: Drilling. After the terminal block is formed, the positioning turntable group drives the segment to rotate to the drilling group, and the drilling group sequentially completes the drilling of the positioning hole and the terminal block. Step d, tapping: After drilling is completed, the positioning turntable group drives the section material to rotate to the tapping group, and the tapping group performs thread tapping on the wiring hole. Step e: Stamping. After tapping, the positioning turntable group drives the segment to rotate to the stamping group, where the stamping group strikes the end of the terminal to form a stamp. Step f, chamfering: After the steel stamp is formed, the positioning turntable group drives the segment material to rotate to the chamfering group, where the chamfering group performs chamfering processing on the positioning hole and the wiring hole; Step g: After the positioning post is formed and chamfered, the positioning turntable group drives the segment material to rotate to the second milling cutter group, where the second milling cutter group processes and forms the positioning post, thus completing the terminal block processing; Step h, Output: After the positioning post is formed, the positioning turntable group drives the terminal block to rotate to the ejector pin group, and the ejector pin group pushes the terminal block out of the positioning turntable group.

[0016] The beneficial effects of this invention are as follows: (1) The present invention uses a positioning turntable group in conjunction with a first milling cutter group, a drilling group, a tapping group, a stamping group, a chamfering group, a second milling cutter group and a pin group to enable the processing steps of the terminal block to be automatically switched between the components without manual intervention. Moreover, all processing steps of the terminal block are completed automatically without manual operation, resulting in a higher degree of automation. (2) The cutting saw assembly of the present invention uses a combination of three synchronous parallel saw blades, namely the first, second and third blades, which not only realizes the fixed-length cutting of bar material into segments, but also simultaneously processes the first and second cutting grooves on the segments. The distance between the two grooves is precisely matched with the thickness of the connecting piece. This changes the traditional step-by-step processing mode of cutting segments first and then grooving, and combines the fixed-length cutting and grooving process of connecting piece thickness into one, reducing equipment stations and processing steps, eliminating secondary clamping and positioning errors, and greatly improving the cutting accuracy and processing efficiency. (3) The present invention adopts a circular production line layout of positioning turntable group + first milling cutter group, drilling group, tapping group, stamping group, chamfering group, second milling cutter group and ejector pin group arranged in circumferential direction. Each station corresponds to a set of positioning slots on the turntable, so that the material section can be intermittently rotated with the turntable and complete the entire process in sequence. It integrates milling, drilling, tapping, stamping, chamfering, forming and unloading into one, realizing the full-process automated continuous production of integrated terminal blocks, replacing multiple single machines for step-by-step processing. The equipment has high integration, small footprint and continuous cycle. (4) The positioning turntable assembly of the present invention consists of a turntable, a connecting block and a clamping block. The clamping block has a positioning groove that conforms to the shape of the material segment, and the material segment can slide and adjust in the positioning groove. It works in conjunction with the top head, limit head and blocking top head of each station to limit the position. The conforming positioning groove is adapted to the shape of the blank. The sliding adjustment structure is compatible with the specification fine adjustment. The station fixed point limit prevents the blank from shifting during processing. The clamping positioning accuracy is high and the versatility is strong, ensuring the consistency of the forming of the connecting piece, the connecting post and the positioning post. (5) The present invention adopts a double-sided split structure for the milling cutter group, drilling group, tapping group and stamping group. One side is the milling cutter, drill bit, tap and stamping head for processing, and the other side is the top head / limiting / blocking top head for bidirectional clamping and alignment. The milling cutter has a built-in forming groove in the center and the two drill bits work on the same side to drill holes. The double-sided top-type processing has balanced force and avoids blank deformation when milling, drilling and tapping on one side. The modular station structure performs its own function and accurately completes the exclusive forming of the terminal, positioning post, terminal hole and positioning hole respectively. The processing and forming accuracy is high and the product yield is significantly improved. (6) The present invention designs a dedicated sequential forming process flow of fixed length cutting → terminal milling → double hole drilling → terminal hole tapping → end steel stamping → hole chamfering → positioning post milling → automatic ejection. It is adapted to the structural features of integrated terminal blocks. The process sequence conforms to the machining logic. The process sequence reasonably avoids process defects such as chamfering before drilling or tapping before stamping. The entire process does not require manual transfer or secondary clamping. It realizes one-stop fully automatic forming from bar stock to finished terminal block, which greatly saves labor costs. The production cycle is standardized and can be mass-produced in batches.

[0017] In summary, this invention has the advantages of high automation, stable continuous operation, close process connection, and high processing efficiency, and is especially suitable for the field of integrated terminal block forming and processing technology. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example 1: like Figures 1-5 As shown, an automatic terminal block forming equipment processes an integrated terminal block 1. The terminal block 1 includes a terminal piece 11, a terminal post 12, and a positioning post 13. The terminal piece 11 is oblong in shape, and the terminal post 12 and the positioning post 13 are respectively disposed on both sides of the terminal piece 11. The automatic forming equipment includes: Cutting saw assembly 21, positioning turntable assembly 22, first milling cutter assembly 23, drilling assembly 24, tapping assembly 25, stamping assembly 26, chamfering assembly 27, second milling cutter assembly 28, and ejector pin assembly 29; The cutting saw assembly 21 cuts the bar stock 10 into segments 100 of a fixed length; The positioning turntable assembly 22 is rotatably arranged, and the positioning turntable assembly 22 is provided with a plurality of positioning grooves 220. The positioning grooves 220 are configured to conform to the shape of the segment material 100, and the positioning grooves are used to position the segment material 100. The first milling cutter group 23, drilling group 24, tapping group 25, stamping group 26, chamfering group 27, second milling cutter group 28, and ejector pin group 29 are arranged sequentially along the circumference of the positioning turntable group 22, and the first milling cutter group 23, drilling group 24, tapping group 25, stamping group 26, chamfering group 27, second milling cutter group 28, and ejector pin group 29 each correspond to a group of positioning grooves 220; The first milling cutter group 23 processes the terminal block 12, the drilling group 24 processes the terminal hole 121 on the terminal block 12 and the positioning hole 111 on the terminal piece 11, the tapping group 25 processes the thread in the terminal hole 121, the stamping group 26 stamps the stamp 122 on the terminal block 12, the chamfering group 27 chamfers the positioning hole 111 and the terminal hole 121, the second milling cutter group 28 processes the positioning post 13, and the ejector pin group 29 ejects the processed terminal block 1 in the positioning groove 220.

[0024] The positioning turntable assembly 22 includes a turntable 221, a connecting block 222, and a clamping block 223. The turntable 221 is self-rotating. Specifically, the turntable 221 is driven by an electric spindle to rotate. When the electric spindle drives the turntable 221 to rotate, an intermittent rotation mode is adopted, so that the material 100 can switch between different workstations while obtaining processing time. Several sets of connecting blocks 222 are provided. The connecting blocks 222 are equidistantly arranged along the circumference of the turntable 221. The connecting blocks 222 and the turntable 221 are connected and fixed by threaded fasteners. The clamping blocks 223 are arranged in a one-to-one correspondence with the connecting blocks 222. The clamping blocks 223 and the connecting blocks 222 are also connected and fixed by threaded fasteners. The clamping blocks 223 are composed of two symmetrically arranged sub-blocks 2231. The clamping blocks 223 have positioning grooves 220. The shape of the positioning grooves 220 is similar to the shape of the bar 10, and the shape of the bar 10 is consistent with the top view outline of the terminal block.

[0025] Furthermore, the segment 100 is slidably adjusted within the corresponding positioning groove 220. Specifically, the segment 100 is inserted and fitted within the positioning groove 220, but by applying external force, the segment 100 can still slide and adjust within the positioning groove 220. At the same time, when the turntable 221 rotates and the segment 100 is transferred and switched, the segment 100 will not fall out of the positioning groove 220. To further explain, the opening on the side of the positioning groove 220 corresponding to the segment 100 being inserted has a certain slope, that is, it is set in the shape of a flared mouth, so that the segment 100 can be smoothly inserted into the positioning groove 220.

[0026] It is worth emphasizing that the clamping structure of the positioning turntable group 22 not only ensures the processing accuracy of the segment material, but also ensures that the processing part can be switched during the processing of the segment material without the need for release and re-clamping like traditional clamps, making the processing more flexible.

[0027] Furthermore, both the first milling cutter group 23 and the second milling cutter group 28 include a milling cutter 231 and a mandrel 232. The milling cutter 231 and the mandrel 232 are respectively disposed on both sides of the corresponding segment 100, and the center of each milling cutter 231 is provided with a forming groove 233. The milling cutter 231 is driven to rotate by a corresponding electric drive system and has a horizontal movement structure, which can move towards the segment. This technology is a conventional technology, so it will not be described in detail in this invention. The mandrel 232 is driven to extend and retract by a corresponding pneumatic component. Before the milling cutter 231 processes the segment 100, the mandrel 232 will first contact the segment 100 before the milling cutter 231, so that the segment 100 is limited. Then the milling cutter 231 contacts the segment processing part and forms a structure. The structure formed by the forming groove 233 is a terminal or positioning post.

[0028] The drilling group 24 is provided in two sets, each corresponding to a forming groove 233 during operation. Each drilling group 24 includes a drill bit 241 and a positioning head 242 respectively disposed on both sides of the corresponding segment 100. The drill bit 241 rotates to form the wiring hole 121 or the positioning hole 111. The positioning head 242 abuts against the segment 100 and blocks the segment 100.

[0029] It should be noted that the drilling group 24 is set with two groups corresponding to the machining of the wiring hole 121 and the positioning hole 111 respectively. The driving method of the drill bit 241 is the same as that of the existing electric drill bit. At the same time, the drill bit 241 has a horizontal movement structure, that is, the drill bit 241 can move towards or away from the segment 100, thereby forming the wiring hole and the positioning hole. Similar to the first milling cutter group and the second milling cutter group, the segment needs to be resisted and limited before machining. The positioning top head 242 is also driven by the corresponding pneumatic component to extend and retract, resisting and limiting the segment.

[0030] The tapping assembly 25 includes a tap 251 and a blocking head 252 respectively disposed on both sides of the corresponding section 100. The tap 251 is rotatably disposed, and the blocking head 252 blocks the section 100.

[0031] It should be noted that the structure of the tapping assembly 25 is similar to that of the drilling assembly, the only difference being the driving method of the machining. The tapping assembly 25 performs tapping machining on the inner ring of the connecting hole 121. The working process and working principle are similar to those of the drilling assembly, so they will not be described in detail here.

[0032] The stamping assembly 26 includes a stamping head 261 and a limiting head 262 respectively disposed on both sides of the corresponding segment 100. The stamping head 261 is telescopically arranged, and the limiting head 262 blocks the segment 100.

[0033] It should be noted that a steel stamp is provided at the end of the terminal block. The steel stamp is formed by the hammering of the steel stamp head 261. The steel stamp head 261 is driven by a corresponding pneumatic component to move telescopically. Before the steel stamp head 261 strikes, the limiting head 262 is also driven by a corresponding pneumatic component to move telescopically, so that the segment is blocked and limited, thereby satisfying the hammering of the steel stamp head 261.

[0034] The chamfering assembly 27 includes chamfering cutter heads 271 and blocking rods 272 respectively disposed on both sides of the corresponding segment 100. The chamfering cutter heads 271 are rotatably disposed, and the blocking rods 272 block the segment 100.

[0035] The chamfering head 271 is also driven by a corresponding electric drive structure, which is existing technology. The chamfering head 271 also has the ability to move horizontally. As mentioned above, before the chamfering head 271 performs processing, it is also stopped by the blocking rod 272. The telescopic structure of the blocking rod 272 is also existing technology.

[0036] The ejector pin assembly 29 includes an ejector pin 291 that is telescopically disposed on one side of the turntable 221. The ejector pin 291 is inserted into the corresponding positioning groove 220 to eject the processed terminal 1, so that the terminal is output through the discharge channel. The ejector pin 291 is driven by the corresponding pneumatic component, and the ejector pin passes into the positioning groove 220 to eject the processed terminal directly from the positioning groove 220.

[0037] Example 2: Referring to Example 1, the difference between Example 2 and Example 1 lies in the following: like Figure 6 and Figure 7 As shown, the cutting saw assembly 21 includes a first saw blade 211, a second saw blade 212, and a third saw blade 213 that rotate synchronously and are arranged in parallel. The first saw blade 211 cuts the bar stock 10 into the segment stock 100, and the second saw blade 212 and the third saw blade 213 respectively form the first cutting groove 101 and the second cutting groove 102 on the segment stock 100.

[0038] The distance between the first cutting groove 101 and the second cutting groove 102 is equal to the thickness of the connector 11.

[0039] It should be noted that when the bar stock 10 is slit, the present invention does not directly cut the bar stock into segments of a fixed length. Instead, during the cutting process, the first cutting groove 101 and the second cutting groove 102 are simultaneously cut on the segments 100 to directly determine the thickness of the connecting piece 11 and obtain the processing reference for the connecting piece 11. The first saw blade 211, the second saw blade 212, and the third saw blade 213 are all driven by the same electric drive structure, which is existing technology and will not be described in detail here. It is important to emphasize that the forming of the first cutting groove 101 and the second cutting groove 102 not only ensures the processing reference for the connecting piece 11, but also forms the processing reference for the positioning post 13. That is, when the second milling cutter group processes the positioning post, the processing of the positioning post is completed when it reaches the position of the first cutting groove 101.

[0040] Example 3: Referring to Example 1, the difference between Example 3 and Example 1 lies in the following: like Figure 8 As shown, a molding method for a fully automatic terminal block molding device based on either Embodiment 1 or Embodiment 2 includes the following steps: Step a: Fixed-length cutting. The long strip of bar 10 is cut into fixed-length segments 100 by the cutting saw group 21. Step b: Terminal forming. The fixed-length section 100 is driven by the clamping of the positioning turntable group 22 to rotate to the first milling cutter group 23, where the first milling cutter group 23 processes and forms a cylindrical terminal 12. Step c: Drilling. After the terminal block is formed, the positioning turntable group 22 drives the segment material 100 to rotate to the drilling group 24, and the drilling group 24 sequentially completes the drilling of the positioning hole 111 and the terminal hole 121. Step d, tapping: After drilling is completed, the positioning turntable group 22 drives the section material 100 to rotate to the tapping group 25, and the tapping group 25 performs thread tapping on the wiring hole 121. Step e: Stamping. After tapping, the positioning turntable group 22 drives the segment material 100 to rotate to the stamping group 26, where the stamping group 26 strikes the end of the terminal 12 to form a stamp. Step f, chamfering: After the steel stamp is formed, the positioning turntable group 22 drives the segment material 100 to rotate to the chamfering group 27, and the chamfering group 27 performs chamfering processing on the positioning hole 111 and the wiring hole 121. Step g: After the positioning post is formed and chamfered, the positioning turntable group 22 drives the segment material 100 to rotate to the second milling cutter group 28, where the positioning post 13 is formed by the second milling cutter group 28, thus completing the processing of the terminal block 1. Step h, Output: After the positioning post is formed, the positioning turntable group 22 drives the terminal block 1 to rotate to the ejector pin group 29, and the ejector pin group 29 pushes the terminal block 1 out from the positioning turntable group 22.

[0041] It should be noted that the processing steps of the terminal forming method of the present invention can be adjusted according to the structure of the forming equipment, that is, step g can also be adjusted to be before step b.

[0042] Furthermore, it should be emphasized that the present invention places the positioning post forming step at the end of the processing steps, which fully considers the strength relationship of the connector during the positioning hole and chamfering of the connector. By placing the positioning post forming step later, the positioning post blank can be used to form a structural reinforcement for the connector during processing, offsetting the impact of the drilling group and chamfering group on the connector, avoiding deformation of the connector during processing, and ensuring processing accuracy.

[0043] like Figure 9 As shown, the two sets of drilling groups 24 of the present invention can be arranged adjacent to each other, that is, after the wiring hole is processed, the positioning hole can be processed directly by rotation. Alternatively, after the wiring hole is drilled, tapping can be performed, and then the positioning hole can be drilled. That is, the two sets of drilling groups 24 are arranged at intervals.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
