Description

Technical Field

[0001] This invention relates to the field of pickle processing equipment technology, and more specifically to automated pickle welding equipment. Background Technology

[0002] Peakball, also known as pickle ball, is a competitive ball sport that combines elements of tennis, table tennis, and badminton. It involves hitting a ball with a racket over a net. Depending on the playing field, peakball is divided into indoor and outdoor types. The commonly used manufacturing process for indoor peakballs is injection molding, where two hemispheres are fused together to form a sphere.

[0003] For example, announcement number CN222407203U, announcement date 2025-01-28, discloses a shell welding device, including a frame, a hot melt plate, and a pressing mechanism. A horizontally arranged guide rod is provided between the side frames, and a closing plate is provided in the middle of the guide rod. A model plate is placed between the two closing plates. The pressing mechanism includes a closing motor, a threaded sleeve, and a lead screw. The threaded sleeve is located in the middle of the side frame, and the lead screw is threadedly connected to the center of the threaded sleeve. One end of the lead screw is rotatably connected to the model plate. The closing plate can be moved between the two model plates by the lead screw to abut against each other, so that the contact distance between the pick ball shell in the cavity of the model plate and the hot melt plate can be precisely controlled with a small difference, effectively controlling the melting degree of the welding plane of the pick ball shell and reducing the burrs on the surface of the pick ball shell.

[0004] The shortcomings of existing pickball welding equipment, including the aforementioned patents, are that, in order to facilitate the separation of the heated hemisphere from the hot melt plate, existing equipment uses a spring placed on the hot melt plate. When the mold moves the hemisphere toward the hot melt plate, it squeezes the spring and compresses it. After heating, the elasticity of the spring can assist in the separation of the heated hemisphere from the hot melt plate. However, due to continuous processing, the spring is prone to failure after being in contact with the hot melt plate for a long time and being heated. Moreover, the heated spring is prone to melting the inner wall of the hemisphere due to excessive temperature, causing the inner wall of the hemisphere to stick to the spring. Summary of the Invention

[0005] The purpose of this invention is to provide an automated equipment for pinball welding.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The automated equipment for welding peaked balls includes a workbench with two parallel mounting frames. Each mounting frame has a vertically mounted bonding template. The two bonding templates are driven to move closer to each other. A hot melt plate is placed above the two bonding templates and is driven to move down between the two bonding templates. Several placement seats for placing hemispheres are fixed to each of the two bonding templates. Each placement seat has a limiter that is driven to restrict the hemisphere within the placement seat.

[0008] The aforementioned automated equipment includes a positioning rod disposed inside the mounting base, with a limiting block slidably mounted on the positioning rod, and the limiting block being driven to move radially along the positioning rod.

[0009] The aforementioned automated equipment has an adjusting component on the mounting frame. When the templates are driven to approach each other, they sequentially pass through the first stroke, the second stroke, and the third stroke. The distance between the two templates is the largest at the beginning of the first stroke. During the second stroke, the adjusting component drives the limiting block to extend outward along the radial direction of the positioning rod. During the third stroke, the adjusting component drives the limiting block to retract inward into the positioning rod.

[0010] The aforementioned automated equipment includes an adjusting component comprising a trigger rod fixed to a mounting frame, an adjusting rod disposed within a positioning rod, one end of the adjusting rod being fixedly connected to a limit block, and an adjusting column fixedly connected to the other end of the adjusting rod. A trapezoidal groove is provided on the trigger rod. When the closing template is in the second stroke, the adjusting column is located in the trapezoidal groove. An elastic element is provided on the closing template corresponding to the positioning rod, and the elastic element maintains the relative position of the adjusting rod and the positioning rod.

[0011] The aforementioned automated equipment is equipped with an ejector mechanism in each mounting seat. In the initial stage when the closing template is driven to move in the reverse direction from the end of the third stroke, the ejector mechanism pushes the whole ball to separate from its mounting seat.

[0012] The aforementioned automated equipment includes an ejection mechanism comprising a push block, which is slidably mounted on the inner side of a mounting base. A guide groove adapted to the push block is provided in the mounting base, and an ejection spring is provided in the guide groove. When the ejection spring is in its natural state, the push block extends outward from the guide groove to its maximum length. A locking member is provided on the mounting base to restrict the push block within the guide groove. The locking member is driven to release the lock on the push block.

[0013] In the aforementioned automated equipment, the locking component is connected to the adjusting rod via a transmission mechanism. When the closing template is at the end of the third stroke, the adjusting rod drives the locking component to release the locking of the push block.

[0014] The aforementioned automated equipment is also equipped with a punching mechanism on its workbench. The punching assembly includes a material handling assembly and a punching assembly. The material handling assembly is driven to move between the two mold plates and pick up the whole ball.

[0015] The aforementioned automated equipment includes a material handling component comprising a movable seat that is driven to move along the length of the worktable to between two mold plates. A material handling seat is mounted on the movable seat and is driven to move along the width of the worktable to cooperate with the punching mechanism to perform punching.

[0016] The aforementioned automated equipment includes a punching component comprising a support frame on which an annular punching blade is mounted, and a discharge chute located on the worktable below the punching blade.

[0017] In the above technical solution, the automated peak ball welding equipment provided by the present invention ensures that the hemisphere is smoothly separated from the hot melt plate by setting a limiting component in the mounting seat and using the limiting component to block the hemisphere. The limiting component has a stable limiting effect on the hemisphere, is not affected by the high temperature on the hot melt plate, and will not damage the inner wall of the hemisphere.

In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] like Figures 1-7As shown, the automated pickle welding equipment provided in this embodiment of the invention includes a workbench 1, on which two parallel mounting frames 11 are installed. Each mounting frame 11 is vertically mounted with a bonding template 2. The two bonding templates 2 are driven to move closer to each other. A hot melt plate 3 is arranged above the space between the two bonding templates 2. The hot melt plate 3 is driven to move down between the two bonding templates 2. Each bonding template 2 is fixed with a plurality of placement seats 21 for placing hemispheres. Each placement seat 21 is provided with a limiting member 4. The limiting member 4 is driven to restrict the hemisphere within the placement seat 21.

[0031] Specifically, this automated welding equipment is used for welding two hemispheres formed by injection molding. Its main structure is a workbench 1. Two sets of parallel mounting brackets 11 are fixed to the front and rear sides of the upper surface of the workbench 1. Two sets of combined templates 2 are vertically arranged between the two mounting brackets 11. Figure 1 As shown, the assembly template 2 is rectangular, and each assembly template 2 is correspondingly arranged with a mounting frame 11. Each mounting frame 11 is equipped with a hydraulic cylinder 111, the output end of which is fixedly connected to the corresponding assembly template 2. This allows the hydraulic cylinder 111 to extend and push its corresponding assembly template 2 towards another assembly template 2. Furthermore, several guide rods 112 are arranged between the two mounting frames 11. Four sets of guide rods 112 are provided, and guide holes for the guide rods 112 are opened at the four corners of each assembly template 2. The guide rods 112 are formed by… Corresponding guide holes pass through to guide the mating template 2; a hot melt plate 3 is also provided above the two mating templates 2; a bracket 12 is installed on both mounting brackets 11, and an adjusting seat 121 is slidably installed on the bracket 12; a cylinder is provided on both mounting brackets 11, and the output end of the cylinder is fixedly connected to the adjusting seat 121; the hot melt plate 3 is vertically installed in the middle of the adjusting plate, and the adjusting seat 121 can be driven to raise and lower the hot melt plate 3 by the extension and retraction of the cylinder; a mounting seat 21 for placing a hemisphere is fixedly connected to both mating templates 2, such as Figures 1 to 4 As shown, four sets of mounting seats 21 are fixed to both of the two composite templates 2. The four sets of mounting seats 21 are distributed in a rectangular array on the composite template 2. Each mounting seat 21 has a hemispherical groove 211 adapted to the outer wall of the pick ball. Each mounting seat 21 is provided with a limiting member 4. The limiting member 4 has a supporting state and a limiting state. When it is in the supporting state, the hemisphere can be placed in the mounting seat 21. When it is in the limiting state, the hemisphere is blocked in the mounting seat 21 and cannot be removed.

[0032] During operation: First, adjust the limiting member 4 to the supporting state, manually place the injection-molded hemisphere into the mounting seat 21, and then adjust the limiting member 4 to the limiting state; Second, drive the adjusting seat 121 to drive the hot melt plate 3 vertically down between the two mold plates 2 (since it is continuous production, the hot melt plate 3 must always be in the open state); Third, drive the two mold plates 2 closer to each other until the hemisphere in the mounting seat 21 is attached to the hot melt area on the hot melt plate 3; Fourth, drive the two mold plates 2 away from each other, use the limiting member 4 to pull the hemisphere away from the hot melt plate 3, and then drive the adjusting seat 121 to drive the hot melt plate 3 vertically upward until the hot melt plate 3 is higher than the two mold plates 2; Fifth, drive the two mold plates 2 closer to each other again until the hemispheres in the two opposing mounting seats 21 on the two mold plates 2 contact and are pressed into a whole ball; Sixth, adjust the limiting member 4 to the supporting state and drive the two mold plates 2 away from each other, and the whole ball can be removed.

[0033] The automated pickball welding equipment provided in this embodiment of the invention uses a limiting member 4 in the mounting seat 21 to block the hemisphere, ensuring that the hemisphere can be smoothly separated from the hot melt plate 3. The limiting member 4 has a stable limiting effect on the hemisphere, is not affected by the high temperature on the hot melt plate 3, and will not damage the inner wall of the hemisphere.

[0034] Furthermore, the limiting member 4 includes a positioning rod 41 disposed inside the mounting base 21, and a limiting block 42 is slidably mounted on the positioning rod 41. The limiting block 42 is driven to move radially along the positioning rod 41.

[0035] Specifically, the limiting component 4 includes a positioning rod 41, such as... Figure 3 and Figure 4 As shown, the positioning rod 41 is fixed to the inner wall of the mounting base 21. Each mounting base 21 has four sets of positioning rods 41 fixed to its inner wall. The end of each positioning rod 41 is frustum-shaped, allowing it to pass through a small hole in the hemisphere. The end of each positioning rod 41 is located within a hemispherical groove 211 on the mounting base 21. A limiting block 42 is slidably mounted on each positioning rod 41, sliding radially along the positioning rod 41. It should be noted that the positioning rod 41 does not pass through the hemisphere along its radius, but rather... Each hole is opened along the radial direction, so the diameter of the positioning rod 41 needs to be smaller than the diameter of the hole on the hemisphere. When the outer wall of the hemisphere is completely in contact with the inner wall of the mounting base 21, the limiting block 42 is located inside the hemisphere. At this time, if the limiting block 42 extends outward along the radial direction of the positioning rod 41, it can contact the inner wall of the hemisphere. In addition, in this embodiment, the template 2 is also provided with a driving component, such as a cylinder, for driving the limiting block 42 to slide radially along the positioning rod 41. The cylinder drives the corresponding limiting block 42 to move radially along the positioning rod 41.

[0036] In actual production, when the hemisphere is placed into the hemisphere groove 211 on the mounting seat 21, the positioning rod 41 needs to pass through the corresponding hole on the hemisphere. Through the cooperation of the four sets of positioning rods 41, the hemisphere is supported. When the cylinder extends, it drives the limiting block 42 to slide radially along the positioning rod 41 until the limiting block 42 extends outside the positioning rod 41. At this time, the limiting block 42 can block the hemisphere from moving axially along the positioning rod 41, thereby limiting the hemisphere. In the fourth step above, when the two combined templates 2 are driven away from each other, the hemisphere can be pulled apart from the hot melt plate 3 by the limiting block 42.

[0037] Furthermore, the mounting frame 11 is provided with an adjusting member 5. When the two mold plates 2 are driven to approach each other, they pass through the first stroke, the second stroke and the third stroke in sequence. At the beginning of the first stroke, the distance between the two mold plates 2 is the largest. In the second stroke, the adjusting member 5 drives the limiting block 42 to extend outward along the radial direction of the positioning rod 41. In the third stroke, the adjusting member 5 drives the limiting block 42 to retract inward into the positioning rod 41.

[0038] Optionally, the adjusting component 5 includes a trigger rod 51 fixedly connected to the mounting bracket 11, an adjusting rod 52 is provided inside the positioning rod 41, one end of the adjusting rod 52 is fixedly connected to the limiting block 42, and the other end of the adjusting rod 52 is fixedly connected to an adjusting column 521. A trapezoidal groove 511 is provided on the trigger rod 51. When the assembly template 2 is in the second stroke, the adjusting column 521 is in the trapezoidal groove 511. An elastic element 6 is provided on the assembly template 2 corresponding to the positioning rod 41. The elastic element 6 maintains the relative position of the adjusting rod 52 and the positioning rod 41.

[0039] Specifically, in the above embodiment, the limiting block 42 is driven to move radially along the positioning rod 41 by a cylinder mounted on the assembly template 2. On the one hand, the space on the assembly template 2 is limited, while the total number of positioning rods 41 in each mounting seat 21 on the same assembly template 2 is relatively large. Given the limited space on the assembly template 2, it is difficult to install too many cylinders. On the other hand, the distance the limiting block 42 slides radially along the positioning rod 41 is small, making it difficult to control with a cylinder. In this embodiment, an adjusting member 5 is provided on the mounting frame 11. The adjusting member 5 includes a trigger rod 51 fixed to the mounting frame 11, such as... Figure 3 and Figure 4As shown, the trigger rod 51 is set along the moving direction of the assembly template 2, which is also the width direction of the worktable 1. Each positioning rod 41 has an adjusting rod 52 set along its own axial direction. The adjusting rod 52 can move radially along the positioning rod 41. The assembly template 2 has a clearance hole through the position corresponding to the adjusting rod 52 so that the adjusting rod 52 can move radially along its corresponding positioning rod 41. One end of the adjusting rod 52 is fixedly connected to the limiting block 42, and the other end of the adjusting rod 52 passes through the mounting base 21 and the assembly template 2 and extends to the corresponding mounting bracket 11. The end of the adjusting rod 52 away from its corresponding limiting block 42 is fixedly connected to an adjusting column 521. The adjusting column 521 always keeps in contact with the trigger rod 51. The trigger rod 51 has a trapezoidal groove 511. The trapezoidal groove 511 is an isosceles trapezoid, which includes an inclined first hypotenuse 5111, a base 5112 and a second hypotenuse 5113, as shown. Figure 4 As shown, to reduce the number of trigger rods 51, among the four sets of adjusting rods 52 (positioning rods 41) corresponding to the same mounting base 21, a set of trigger rods 51 is provided between the two sets of adjusting rods 52 distributed vertically. Two sets of trapezoidal grooves 511 are provided on the trigger rods 51, symmetrically arranged vertically about the trigger rods 51. One end of the trigger rod 51 is fixedly connected to the mounting bracket 11. Furthermore, an elastic element 6 is provided on the assembly template 2 corresponding to the positioning rods 41. The elastic element 6 maintains the relative position of the adjusting rods 52 and the positioning rods 41, such as... Figure 4 As shown, the elastic element 6 includes a fixing block 61 fixed to the template 2. A guide post 62 is fixed to the adjusting rod 52 at the position corresponding to the fixing block 61. One end of the guide post 62 passes through the fixing block 61 and forms an annular protrusion along its own circumference. A limit spring 63 is fitted on the guide post 62. When the limit spring 63 is in the natural state, the adjusting rod 52 pushes the limit block 42 to extend outside the positioning rod 41.

[0040] During the production process, the pushing force of the limiting spring 63 on the adjusting rod 52 keeps the adjusting column 521 in contact with the trigger rod 51. When the closing template 2 is in the first stroke, the adjusting column 521 slides from the end of the trigger rod 51 away from the closing template 2 toward the middle of the trigger rod 51. When the closing template 2 reaches the end of the first stroke, the adjusting column 521 slides to the position of the first inclined side 5111 of the trigger rod 51 near the trapezoidal groove 511. During this process, the limiting block 42 is always inside the positioning rod 41.

[0041] When the mold plate 2 is in the second stroke, the adjusting column 521 first slides along the first inclined side 5111 of the trapezoidal groove 511 towards the bottom side 5112. At this time, the adjusting rod 52 pushes the limiting block 42 to gradually extend outward from the positioning rod 41. When the adjusting column 521 slides to the bottom side 5112 of the trapezoidal groove 511, the length of the limiting block 42 extending outward from the positioning rod 41 reaches its maximum. When the adjusting column 521 slides to one end of the bottom side 5112 of the trapezoidal groove 511 corresponding to the second inclined side 5113, the second stroke ends. At this time, the mold plate 2 drives each hemisphere to move to contact the hot melt plate 3. In this way, after the hemisphere is hot melted, in the early stage when the mold plate 2 is driven to move in the opposite direction, the adjusting column 521 slides along the bottom side 5112 of the trapezoidal groove 511. During this process, the limiting block 42 always maintains the maximum extension amount, thereby pulling the hemisphere to separate from the hot melt plate 3.

[0042] When the mold plate 2 is in the third stroke, the adjusting column 521 first slides along the second inclined side 5113 of the trapezoidal groove 511. At this time, the adjusting rod 52 drives the limiting block 42 to gradually move from the outside of the positioning rod 41 to the inside. When the adjusting column 521 slides to the end of the second inclined side 5113 that is far away from the bottom edge 5112, the limiting block 42 moves completely into the inside of the positioning rod 41. It should be noted that the mold plate 2 is only in the third stroke when the two hemispheres are welded (as described above). The length of the third stroke is half the thickness of the hot melt plate 3.

[0043] In this embodiment, by adjusting the column 521 and the trigger rod 51, the synchronous driving of each limit block 42 is passively realized during the driving movement of the template 2.

[0044] In another embodiment of the present invention, each mounting seat 21 is provided with an ejection mechanism 7. When the template 2 is driven to move in the reverse direction from the end of the third stroke, the ejection mechanism 7 pushes the whole ball to separate from its mounting seat 21.

[0045] Specifically, since the two mold plates 2 move towards each other, pushing the two hemispheres closer together until they contact and are forcibly squeezed to achieve the fusion of the two hemispheres, during the fusion process, there will be annular scraps on the outer wall of the formed whole ball. When the two mold plates 2 are driven away from each other, the scraps will stick to the end face of a set of mounting seats 21 (which may be any mounting seat 21 on the mold plate 2), making it inconvenient to remove from the mounting seat 21. In this embodiment, each mounting seat 21 is provided with an ejection mechanism 7. In the initial stage when the mold plate 2 is driven to move in the opposite direction from the end of the third stroke, that is, at the beginning of the sixth step mentioned above, the ejection mechanism 7 pushes the whole ball to separate from the mounting seat 21 where it is located. Optionally, the ejection mechanism 7 is a cylinder fixed to the mold plate 2. The output end of the cylinder passes through the mold plate 2 and the corresponding mounting seat 21 in sequence. With this configuration, after the fusion of the two hemispheres is completed, the cylinder can be extended to push the whole ball to separate from the mounting seat 21.

[0046] Furthermore, the ejection mechanism 7 includes a push block 71, which is slidably mounted on the inner side of the mounting base 21. The mounting base 21 has a guide groove 212 adapted to the push block 71. An ejection spring 72 is provided in the guide groove 212. When the ejection spring 72 is in its natural state, the push block 71 extends outward from the guide groove 212 to its maximum length. The mounting base 21 is provided with a locking member 8 for restricting the push block 71 in the guide groove 212. The locking member 8 is driven to release the lock on the push block 71.

[0047] Specifically, in the above embodiment, to ensure the limiting effect on the hemisphere, when the hemisphere is in contact with the inner wall of the mounting base 21, the limiting block 42 is located inside the hemisphere, and when the limiting block 42 extends, it can contact the inner wall of the hemisphere. This ensures that the hemisphere can only be limited when it is completely in contact with the inner wall of the mounting base 21 and the limiting block 42 extends. If the hemisphere is not completely in contact with the inner wall of the mounting base 21, either the limiting block 42 will be blocked by the hole wall of the upper hole of the hemisphere and cannot extend smoothly, or the limiting block 42 will... 2 is located outside the hemisphere. At this time, although the limiting block 42 can extend smoothly, it cannot limit the hemisphere, which will make it difficult for the hemisphere to detach smoothly from the hot melt plate 3. The thickness of the peak ball (the difference between the outer diameter and the inner diameter) is small, and in order to ensure that the hemisphere can be successfully hot melted during the production process, the hemisphere originally needs to protrude from the mounting base 21 when placed in the mounting base 21. This makes it difficult to observe with the naked eye whether the hemisphere is placed in place (completely in contact with the inner wall of the mounting base 21). In this embodiment, as Figure 4As shown, the ejection mechanism 7 includes a push block 71, which is slidably mounted on the inner side of the mounting base 21. The mounting base 21 has a guide groove 212 that communicates with the upper hemispherical groove 211 of the mounting base 21. An ejection spring 72 is provided in the guide groove 212. The mounting base 21 also has a locking member 8 for restricting the push block 71 in the guide groove 212. The locking member 8 is driven to release the lock on the push block 71.

[0048] Push block 71 has a retracted position and an extended position during its sliding stroke along guide groove 212:

[0049] When in the retracted position, the push block 71 is in a position that can be locked by the locking member 8. When in this position, the deformation of the push spring 72 is the largest.

[0050] When in the extended position, the locking member 8 cannot lock the push block 71, and at this time the push block 71 extends outward from the guide groove 212 to its maximum length.

[0051] With this configuration, after the injection-molded hemisphere is placed into the mounting base 21, if the hemisphere can completely fit against the inner wall of the mounting base 21 (fully positioned), the push block 71 can be successfully locked. However, if the hemisphere cannot completely fit against the inner wall of the mounting base 21, the push block 71 cannot be locked. After the hemisphere is released, the ejector spring 72 will return to its original position and push the push block 71 from the retracted position to the extended position, thereby pushing the hemisphere outward a certain distance. This allows the operator to visually observe whether the hemisphere is positioned correctly. Preferably, the surface of the push block 71 away from the ejector spring 72 is adapted to the shape of the outer wall of the hemisphere. This configuration allows the entire ball to be pushed outward from the mounting base 21 by sliding the push block 71 in the guide groove 212, and also allows for monitoring whether the hemisphere is positioned correctly.

[0052] Furthermore, the locking element 8 is connected to the adjusting rod 52 in a transmission manner. When the closing template 2 is at the end of the third stroke, the adjusting rod 52 drives the locking element 8 to release the lock on the push block 71.

[0053] Specifically, such as Figure 5 As shown, the locking component 8 includes a limiting wedge 81, which is slidably installed in the mounting base 21. The push block 71 has an insertion hole 82 for engaging the limiting wedge 81. The mounting base 21 is provided with an adjusting spring 83 to maintain the relative position of the limiting wedge 81 and the push block 71. When the adjusting spring 83 is in its natural state, the limiting wedge 81 is inserted into the insertion hole 82 on the push block 71, at which point the push block 71 is in a locked state. In this embodiment, as... Figure 4As shown, each mounting base 21 has a set of adjusting rods 52, including a first rod 522 and a second rod 523. The structure of the remaining adjusting rods 52 is the same as in the above embodiment. The width of the first rod 522 is greater than the width of the second rod 523. The end of the second rod 523 away from the limiting block 42 is slidably connected to the first rod 522. The sliding direction of the second rod 523 on the first rod 522 is the same as the extension direction of the limiting block 42. Figure 5 As shown, a limiting post 525 is fixedly connected to the second rod 523, extending through to the outside of the first rod 522. A limiting block 42 is fixedly connected to the end of the second rod 523 away from the first rod 522, while an adjusting post 521 is fixedly connected to the end of the first rod 522 away from the second rod 523. A maintaining spring 524 is provided on the first rod 522 to maintain the relative position of the first rod 522 and the second rod 523. Furthermore, a limiting wedge 81 is drively connected to the adjusting rod 52. Figure 4 and Figure 5 As shown, a connecting rod 811 is fixedly connected to the limiting wedge block 81. The end of the connecting rod 811 away from the limiting wedge block 81 passes through the first rod 522 and forms an annular protrusion along its circumference. At the same time, a protrusion 512 with a right-angled trapezoidal cross section is fixedly connected to the trigger rod 51. When the adjusting column 521 slides along the trigger rod 51, the two sides passing through the protrusion 512 are the third inclined side 5121 and the top side 5122 in sequence. The third inclined side 5121 and the second inclined side 5113 of the trapezoidal groove 511 are on the same straight line.

[0054] With this configuration, as the adjusting column 521 moves along the surface of the trigger rod 51, the first rod 522 has a first position, a second position, and a third position relative to its corresponding mounting seat 21:

[0055] When in the first position, the limiting block 42 is always inside the positioning rod 41;

[0056] When in the second position, the length of the limiting block 42 extending outside the positioning rod 41 is at its maximum. At this time, the adjusting column 521 contacts the bottom edge 5112 of the trapezoidal groove 511.

[0057] When in the third position, the limiting block 42 is always inside the positioning rod 41. At the same time, the first rod 522 pulls the limiting wedge 81 and the push block 71 completely apart through the connecting rod 811. That is, the push block 71 is in the unlocked state at this time, and the mold plate 2 is at the end of the third stroke. This allows the two hemispheres to move in the opposite direction (gradually away from the other mold plate 2) after they are welded together. The ejector spring 72 can push the push block 71 to push the whole ball outward from the mounting seat 21 where the push block 71 is located.

[0058] When the template 2 is in the third stroke, the adjusting column 521 moves to the second inclined side 5113 of the trapezoidal groove 511 on the trigger rod 51. Guided by the second inclined side 5113, the adjusting column 521 pushes the first rod 522 from the second position to the first position. During this process, the first rod 522 drives the second rod 523 to move synchronously. The second rod 523 drives the limiting block 42 to move into the positioning rod 41. When the adjusting column 521 moves to the third inclined side 5121 of the protrusion 512 on the trigger rod 51, the first rod 522 is in the first position. At this time, the second rod 523 abuts against the inner wall of the positioning rod 41. The position cannot be moved further. When the adjusting column 521 moves along the third inclined side 5121 of the protrusion 512 towards the top side 5122, the first rod 522 continues to move. At this time, the annular protrusion on the connecting rod 811 contacts the first rod 522 and moves under the push of the first rod 522. The connecting rod 811 pulls the limiting wedge 81 away from the push block 71. When the adjusting column 521 moves to the position where the top side 5122 of the protrusion 512 is located, the limiting wedge 81 is completely separated from the push block 71. At this time, the locking of the push block 71 is released, so that the push block 71 can push the fused whole ball to separate from the mounting seat 21.

[0059] Because the diameter of the positioning rod 41 is small, the adjustment rod 52 can only move a limited distance radially along the positioning rod 41. It can only move the limiting block 42 into the interior of the positioning rod 41, but cannot continue to move to pull the connecting rod 811, so that the connecting rod 811 pulls the limiting wedge 81 to separate from the push block 71. In this embodiment, the adjustment rod 52 is divided into a first rod 522 and a second rod 523, and the first rod 522 has a first position, a second position and a third position, so that the first rod 522 is displaced a distance more than the second rod 523. In the third stroke of the template 2 movement, the distance that the first rod 522 is displaced more than the second rod 523 is used to passively release the locking of the limiting wedge 81 to the push block 71.

[0060] In another embodiment of the present invention, a punching mechanism 9 is also provided on the workbench 1. The punching component 92 includes a material taking component 91 and a punching component 92. The material taking component 91 is driven to move between the two mold plates 2 and take the whole ball.

[0061] Furthermore, the material handling assembly 91 includes a movable seat 911, which is driven to move along the length direction of the worktable 1 to between the two mold plates 2. A material handling seat 912 is installed on the movable seat 911, which is driven to move along the width direction of the worktable 1 to cooperate with the punching mechanism 9 to perform punching.

[0062] Furthermore, the punching assembly 92 includes a support frame 921, on which an annular punching blade 922 is mounted, and a discharge chute 13 is provided on the worktable 1 below the punching blade 922.

[0063] Specifically, because the two hemispheres are pushed closer together by the opposing movement of the two mold plates 2 until they contact and press against each other to achieve fusion, sufficient extrusion pressure is required during the fusion process. This results in annular scraps on the outer wall of the formed sphere. These scraps need to be removed, otherwise it will affect the use of the peak ball. In this embodiment, the worktable 1 is also equipped with a punching mechanism 9, such as... Figure 1 and Figure 6 As shown, the punching mechanism 9 includes a material taking component 91 and a punching component 92. The material taking component 91 includes a movable seat 911, which is slidably mounted on the worktable 1 and is driven to slide along the length direction of the worktable 1 (the two mold plates 2 mentioned above both move along the width direction of the worktable 1). A material taking seat 912 is movably mounted on the movable seat 911. The material taking seat 912 is also provided with a hemispherical groove 211. The hemispherical groove 211 on the material taking seat 912 corresponds one-to-one with the mounting seat 21 on the mold plate 2. The material taking seat 912 is driven to move along the width direction of the worktable 1. The driving of the movable seat 911 and the material taking seat 912 can be achieved by using an existing linear drive mechanism. This is prior art and will not be described in detail.

[0064] After the two hemispheres are welded, one assembly template 2 is moved in the opposite direction, while the other assembly template 2 remains in place. For ease of description, the assembly template 2 that moves first is called the first plate, and the other assembly template 2 is called the second plate. At this time, the push blocks 71 in each mounting seat 21 on the first plate push the whole ball away from the mounting seat 21, so that the whole ball can be retained in the mounting seat 21 on the second plate. After the first plate is completely reset, the moving seat 911 is driven to move between the two assembly templates 2. At this time, the hemisphere grooves 211 on the picking seat 912 are aligned with the mounting seats 21 on the second plate, driving the picking seat 912 to move towards the second plate until half of the whole ball in each mounting seat 21 on the second plate is in the hemisphere grooves 211 on the picking seat 912. At this time, the second plate is driven to move in the opposite direction, through the mounting seats 21 on the second plate... The pusher 71 in the seat 21 pushes the whole ball to separate from the seat 21, so that the whole ball is left in the hemispherical groove 211 on the picking seat 912. Then, the picking seat 912 is reset first, and then the moving seat 911 is driven to reset. After the moving seat 911 is reset, the picking seat 912 is directly opposite the punching mechanism 9. The punching mechanism 9 includes a support frame 921, on which a ring-shaped punching blade 922 is installed. The punching blade 922 and the hemispherical groove 211 on the picking seat 912 are arranged one-to-one. When the picking seat 912 is driven to move toward the punching blade 922, the whole ball is pushed to the inside of the punching blade 922, and the annular scrap of the edge of the whole ball is cut off by the punching blade 922. A discharge groove 13 is provided on the worktable 1 below the punching blade 922. The whole ball that has been cut falls into the discharge groove 13.

[0065] During the resetting process of the moving seat 911, in order to ensure that the whole ball will not fall off the picking seat 912, an electrically controlled clamp can be installed in the hemispherical groove 211; in order to ensure that the whole ball after punching can fall smoothly, a cylinder can be installed on the picking seat 912 corresponding to the hemispherical groove 211. When the cylinder extends, its output end can extend into the hemispherical groove 211 and push the whole ball out. Using an electrically controlled clamp to restrict a ball in the hemispherical groove 211 is existing technology, which can be directly applied and will not be elaborated.

[0066] To improve production efficiency, a feeding component 14 can be installed on the workbench 1. The structure of the feeding component 14 is the same as that of the feeding mechanism in the cited patent, and can be directly applied without further explanation.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
