[0002] Massage comb teeth are commonly used combing tools in people's daily lives. Since the beads at the end of the massage comb teeth contact the scalp over a larger area and provide stronger stimulation, this point massage is very significant and has a good massage effect, and can make hair fuller and fluffier, so it is popular among users. When assembling the comb bead head with the silicone body, manual material picking and assembly are adopted. In addition, the beads of the conventional massage comb bead heads are of different sizes, the shape of the bead heads is unstable and the bead heads are not round enough. Due to the inconsistent strength of each operator and the one-time assembly, manual assembly cannot guarantee the stability of the comb bead head and the silicone body, and cannot improve the assembly firmness of the comb bead head and the silicone body, which increases the rework rate. In addition, the comb bead head is a connected whole after injection molding, and it needs to be hot-cut to separate the independent comb bead heads. In the past, it was also completed by manual hot-cut operation mode. Pure manual operation will make the production cycle unstable and greatly increase the labor cost. In summary, it is necessary to develop and design a complete set of equipment, which can greatly reduce the labor operation cost, make the operation cycle more stable, the product can be stably output, shorten the working time, improve efficiency, and eliminate many quality defects caused by manual material picking and assembly to solve the problems in actual production.

[0013] Directions:

[0014] Step 1, installation of comb teeth and silicone body: First, the operator puts the comb teeth into the jig that carries the comb teeth, and then puts the comb teeth jig loaded with comb teeth on the hot-cut carrier positioning mold closest to the handling, clamping and pre-insertion module position of each hot-cut module group for clamping and fixing. Three hot-cut carrier positioning molds are arranged equidistantly in a straight line structure on each hot-cut module group, and these three hot-cut carrier positioning molds are connected as a whole by equidistant stainless steel cylinders to facilitate the horizontal movement of the whole set. At the same time, the operator puts the silicone body to be assembled with the comb teeth into the silicone body positioning and rotating mold closest to the handling, clamping and pre-insertion module position of the pre-insertion pressing module group for clamping and fixing. Similarly, the pre-insertion pressing module group is also provided with equidistant stainless steel cylinders in a straight line structure. Three silicone body positioning rotating molds are arranged, and these three silicone body positioning rotating molds are connected into one body by equidistant stainless steel cylinders, which is also convenient for the horizontal movement of the whole set. Then, turn on the start button on the touch screen, and under the action of the electric control cabinet, let the hot cutting carrier conveyor belt in each hot cutting module group operate, and at the same time, let the pre-insertion pressing carrier conveyor belt in the pre-insertion pressing module group operate, so that the hot cutting carrier positioning mold closest to the transport clamping pre-insertion module position in each hot cutting module group is conveyed to the position at the bottom of the hot cutting device under the transmission of the hot cutting carrier conveyor belt, and at the same time, let the silicone body positioning rotating mold closest to the transport clamping pre-insertion module position in the pre-insertion pressing module group be conveyed to the position at the bottom of the pressing device under the transmission of the pre-insertion pressing carrier conveyor belt;

[0015] Step 2, comb teeth hot cutting material head: when the hot cutting carrier positioning mold closest to the handling clamping pre-insertion module position in each hot cutting module group is transmitted to the position below the hot cutting device under the transmission of the hot cutting carrier conveyor belt, the hot cutting carrier conveyor belt will automatically stop, so that the comb teeth fixture loaded with comb teeth in the hot cutting carrier positioning mold will be retained directly below the hot cutting device, and the hot cutting device is used to hot cut the comb teeth in the comb teeth fixture in the hot cutting carrier positioning mold, and the connecting material head of the comb teeth is hot cut, so that the original comb teeth injection molding integrated part is hot cut into each comb tooth independent individual, which is convenient for subsequent clamping and pressing. Under the action of the electric control cabinet, the hot cutting operations in the two groups of hot cutting modules are carried out together;

[0016] Step 3: Comb teeth positioning and flipping: When the material head in the comb teeth fixture is cut off, the hot cutting carrier conveyor belts in the two sets of hot cutting modules will start at the same time, and the comb teeth fixtures loaded with comb teeth after cutting are transferred to the two comb teeth positioning and flipping devices at the end of each set of hot cutting modules. The two comb teeth positioning and flipping devices are mirror-image structures and are located on both sides of the hot cutting carrier conveyor belt. They are used to clamp the comb teeth after hot cutting and flip them 90 degrees. First, the flipping drive device clamps the comb teeth in the comb teeth fixture in the hot cutting carrier positioning mold with two comb teeth clamping pliers on one side of the comb teeth. Then, under the push of the lifting drive device, the comb teeth in the comb teeth fixture in the hot cutting carrier positioning mold are flipped. The flip support platform is lifted upward along the four lifting and positioning rods. The four lifting and positioning rods play a role of telescopic positioning, standardizing the moving trajectory of the flip support platform and keeping the flip support platform away from the base. Since the flip bracket is installed on the upper part of the flip support platform, as the flip support platform is lifted, the flip driving device on the flip bracket is driven to move the two comb tooth clamps on the comb tooth side to separate the already clamped comb teeth from the comb tooth fixture in the hot cutting carrier positioning mold. Then, the comb teeth clamped by the two comb tooth clamps are driven by the flip driving device to rotate upward 90°, so that the comb teeth are converted from a horizontal placement state to a vertical placement state, so as to facilitate the subsequent extraction of the comb tooth clamping device;

[0017] Step 4, automatic clamping, pre-insertion and pressing of comb teeth: when the comb teeth in the comb tooth fixture in the hot-cut carrier positioning mold are turned over, the comb tooth clamping device on the transport clamping and pre-insertion mold group will extract the comb teeth that have been turned over and are in a vertical position. Then, the transport drive motor drives the transport linkage device, and the transport linkage device adopts a slideway transmission belt, so that the comb tooth clamping device connected to the transport linkage device can move horizontally along the transport linkage device. Then, the comb teeth extracted by the comb tooth clamping device are inserted into the silicone body in the silicone body positioning rotating mold on the pre-insertion and pressing mold group that is closest to the transport clamping and pre-insertion mold position. After the pre-insertion is completed once, the silicone body positioning rotating mold is driven by the pre-insertion and pressing carrier conveyor belt and is conveyed to the pressing The comb teeth after pre-insertion are pressed directly below the closing device, thereby completing one pre-insertion and pressing of the comb teeth. It is necessary to use the comb tooth clamping device to repeatedly pre-insert and press one comb tooth three times, that is, pre-insert once and press once, for a total of three times, so that the comb teeth and the silicone body are assembled more firmly; the comb tooth clamping device is used in conjunction with the pressing device, and after completing the pre-insertion and pressing operation of the current comb teeth, the comb teeth in each group of hot-cutting modules that have been flipped 90° by the comb tooth positioning flipping device are clamped and transmitted, and three pre-insertion and pressing are completed, so that the comb teeth in the comb tooth fixture in the hot-cutting carrier positioning mold at the current position in each group of hot-cutting modules and the silicone body inside the silicone body positioning rotating mold in the pre-insertion and pressing module complete the pre-insertion and pressing operation;

[0018] Step 5. Removal of assembled finished products: After the comb teeth and silicone body pre-insertion and pressing of the three hot-cut carrier positioning dies on the top of each hot-cut module group and the three silicone body positioning rotating dies on the top of the pre-insertion and pressing module group are at the same horizontal line, the operator is responsible for manually taking out the silicone body finished parts with comb teeth that have been assembled in the silicone body positioning rotating dies on the top of the pre-insertion and pressing module group;

[0019] Step 6, cyclic operation: while the comb teeth and silicone body at the same horizontal position of the three hot cutting carrier positioning molds on the top of each group of hot cutting modules and the three silicone body positioning rotating molds on the top of the pre-insertion and pressing modules are automatically pre-inserted and pressed, the operator can continue to put the comb teeth into the jig carrying the comb teeth, and put the comb teeth jig with comb teeth into the vacant hot cutting carrier positioning mold. Similarly, the operator can continue to put the silicone body into the vacant silicone body positioning rotating mold for subsequent pre-insertion and pressing; the operator can put the comb teeth jig loaded with comb teeth and the silicone body into the three hot cutting carrier positioning molds and the three silicone body positioning rotating molds at one time, or can place the comb teeth jig loaded with comb teeth and the silicone body while performing the pre-insertion and pressing operation. The operation is flexible and changeable, and the pre-insertion and pressing operations of steps one to five are repeatedly performed.

[0020] The beneficial effects of the present invention are as follows: the automatic assembly mechanism is used for the assembly of the comb tooth bead head and the silicone body. The whole set of equipment adopts a design concept combining a double-station hot cutting mechanism with an assembly pressing mechanism, and is used in the installation process of the comb tooth bead head and the silicone body, thereby realizing the repeated operations of automatic hot cutting, automatic flipping, automatic clamping, pre-insertion and pressing of the comb tooth material head, thereby saving the cycle operation time, shortening the working time by using the stroke planning, eliminating the manual material taking and assembly, and the operation and assembly time of a finished product is about 25 seconds, excluding the manual loading and unloading time, making the operation cycle more stable, improving the work efficiency and reducing the labor cost.

Each hot-cutting carrier positioning mold 7 adopts a steel carrier for the clamping of the comb tooth fixture, which is not easy to be damaged during baking and hot-cutting operations; at the same time, the operator puts the silicone body to be assembled with the comb teeth into the silicone body positioning rotating mold 19 closest to the handling clamping pre-insertion mold 21 of the pre-insertion pressing mold group 17 for clamping and fixing. Similarly, three silicone body positioning rotating molds 19 are arranged equidistantly in a straight line structure on the pre-insertion pressing mold group 17, and these three silicone body positioning rotating molds The molds 19 are connected as one by equidistant stainless steel cylinders, which is also convenient for the horizontal movement of the whole set. Then, the start button on the touch screen 27 is turned on. Under the action of the electric control cabinet 1, the hot cutting carrier conveyor belt 6 in each hot cutting module group 5 is operated, and the pre-insertion pressing carrier conveyor belt 18 in the pre-insertion pressing module group 17 is also operated, so that the hot cutting carrier positioning mold 7 in each hot cutting module group 5, which is closest to the handling clamping pre-insertion module 21, is transmitted to the lower part of the hot cutting device 16 under the transmission of the hot cutting carrier conveyor belt 6. At the same time, the silicone body positioning rotating mold 19 at the position closest to the handling and clamping pre-insertion mold 21 in the pre-insertion and pressing mold group 17 is also transmitted to the position at the bottom of the pressing device 20 under the transmission of the pre-insertion and pressing carrier conveyor belt 18. The hot-cutting carrier conveyor belt 6 and the pre-insertion and pressing carrier conveyor belt 18 both adopt double-track servo-driven conveyor belts with CNC drive, which can ensure the accuracy of the movement of the three hot-cutting carrier positioning molds 7 and the three silicone body positioning rotating molds 19, thereby standardizing the travel trajectory.

[0041] Step 2, comb teeth hot cutting material head: when the hot cutting carrier positioning mold 7 closest to the handling clamping pre-insertion module 21 in each hot cutting module group 5 is transmitted to the position below the hot cutting device 16 under the drive of the hot cutting carrier conveyor belt 6, the hot cutting carrier conveyor belt 6 will automatically stop, so that the comb teeth fixture loaded with comb teeth in the hot cutting carrier positioning mold 7 will be retained directly below the hot cutting device 16, and the hot cutting device 16 is used to hot cut the comb teeth in the comb teeth fixture in the hot cutting carrier positioning mold 7, and hot cut the connecting material head of the comb teeth, so that the original comb teeth injection molding one-piece is hot cut into each comb tooth independent individual, which is convenient for subsequent clamping and pressing. Under the action of the electric control cabinet 1, the hot cutting operations in the two groups of hot cutting modules 5 are carried out together.

[0042] Step 3, comb teeth positioning and flipping: when the material head in the comb teeth fixture is cut off, the hot cutting carrier conveyor belts 6 in the two groups of hot cutting modules 5 will start at the same time, and the comb teeth fixtures loaded with comb teeth after cutting are conveyed to the two comb teeth positioning and flipping devices 8 at the end position of each group of hot cutting modules 5. The two comb teeth positioning and flipping devices 8 are mirror-image structures and are located on both sides of the hot cutting carrier conveyor belt 6, respectively, for clamping the comb teeth after hot cutting and flipping 90°. Each comb teeth positioning and flipping device 8 is composed of a base 9, a lifting drive device 10, four lifting positioning rods 11, a flip support platform 12, a flip bracket 13, a flip drive device 14 and two comb teeth clamping pliers 15. First, the flip drive device 14 clamps the comb teeth in the comb teeth fixture in the hot cutting carrier positioning mold 7 with the two comb teeth clamping pliers 15 on the comb teeth side. The comb teeth clamping pliers 15 are all automatic clamps, which are easy to set and control. Then , driven by the lifting drive device 10, the flip support platform 12 is lifted upward along the four lifting positioning rods 11. The four lifting positioning rods 11 play a role of telescopic positioning, standardizing the moving trajectory of the flip support platform 12 and keeping the flip support platform 12 away from the base 9. Since the flip bracket 13 is installed on the upper part of the flip support platform 12, as the flip support platform 12 is lifted, the flip drive device 14 on the flip bracket 13 is driven to move toward the two comb tooth clamping pliers 15 on the comb tooth side to separate the clamped comb teeth from the comb tooth fixture in the hot cutting carrier positioning mold 7. Then, the comb teeth clamped by the two comb tooth clamping pliers 15 are driven by the flip drive device 14 to rotate upward 90°. The flip drive device 14 adopts a servo motor driver, so that the flip drive device 14 can drive the flip bracket 13 to move more accurately, so that the comb teeth are converted from a horizontal placement state to a vertical placement state, so as to facilitate the subsequent extraction of the comb tooth clamping device 25.

[0043] Step 4: Automatically clamp, pre-insert and press the comb teeth: When the comb teeth in the comb teeth fixture in the hot-cut carrier positioning mold 7 are turned over, the comb teeth clamping device 25 on the handling, clamping and pre-insertion module 21 will extract the comb teeth that have been turned over and are in a vertical position. The comb teeth clamping device 25 also uses an automatic clamp, which is easy to set and control, and is used to clamp the turned comb teeth. A comb teeth pre-insertion drive motor 26 is also installed on the upper part of the comb teeth clamping device 25. The comb teeth pre-insertion drive motor 26 also uses a servo drive. The motor driver is used to drive the comb teeth clamping device 25 to push downward so as to complete the pre-insertion operation between the comb teeth and the silicone body; then, the transport drive motor 24 drives the transport linkage device 23, and the transport drive motor 24 also adopts a servo motor driver, so as to drive the transmission distance and position of the transport linkage device 23 to be more accurate, and the transport linkage device 23 adopts a slide-type transmission belt, so that the comb teeth clamping device 25 connected to the transport linkage device 23 can move horizontally along the transport linkage device 23, and then, the comb teeth clamping device 25 The extracted comb teeth are inserted into the silicone body in the silicone body positioning rotary mold 19 on the pre-insertion and pressing mold group 17, which is closest to the position of the transport clamping and pre-insertion mold group 21. After the pre-insertion is completed once, the silicone body positioning rotary mold 19 is driven by the pre-insertion and pressing carrier conveyor belt 18 and is conveyed to the bottom of the pressing device 20 to press the pre-inserted comb teeth, thereby completing the pre-insertion and pressing of the comb teeth. The comb tooth clamping device 25 is required to repeatedly perform pre-insertion and pressing on a comb tooth three times, that is, pre-insertion once and pressing once, for a total of three times. The comb teeth and the silicone body are assembled more firmly; the comb tooth clamping device 25 is used in conjunction with the pressing device 20 to complete the pre-insertion and pressing operation of the current comb teeth, and then the comb teeth in each group of hot cutting modules 5 that have been flipped 90° by the comb tooth positioning and flipping device 8 are clamped and transmitted, and three pre-insertion and pressing are completed, so that the comb teeth in the comb tooth fixture in the hot cutting carrier positioning mold 7 at the current position in each group of hot cutting modules 5 and the silicone body inside the silicone body positioning rotating mold 19 in the pre-insertion and pressing module 17 complete the pre-insertion and pressing operation.

[0044] Step 5. Removal of assembled finished products: After the comb teeth and silicone body pre-insertion and pressing of the three hot-cutting carrier positioning molds 7 on the top of each group of hot-cutting molds 5 and the three silicone body positioning rotating molds 19 on the top of the pre-insertion and pressing mold group 17 are at the same horizontal position, the operator is responsible for manually taking out the assembled silicone body finished parts with comb teeth in the silicone body positioning rotating mold 19 on the top of the pre-insertion and pressing mold group 17.

[0045] Step 6, cyclic operation: while the comb teeth and silicone body at the same horizontal position of the three hot-cutting carrier positioning molds 7 on the top of each group of hot-cutting modules 5 and the three silicone body positioning rotating molds 19 on the top of the pre-insertion and pressing module group 17 are automatically pre-inserted and pressed, the operator can continue to put the comb teeth into the jig carrying the comb teeth, and put the comb teeth jig with comb teeth into the vacant hot-cutting carrier positioning mold 7. Similarly, the operator can continue to put the silicone body into the vacant silicone body positioning rotating mold 19 for subsequent pre-insertion and pressing; the operator can put the comb teeth jig loaded with comb teeth and the silicone body into the three hot-cutting carrier positioning molds 7 and the three silicone body positioning rotating molds 19 at one time, or can put the comb teeth jig loaded with comb teeth and the silicone body while performing the pre-insertion and pressing operation. The operation is flexible and changeable, and the pre-insertion and pressing operations of steps 1 to 5 are repeatedly performed.

[0046] The whole set of equipment adopts the design concept of combining a double-station hot cutting mechanism with an assembly and pressing mechanism, which is used in the installation process of the comb tooth bead head and the silicone body, thereby realizing the repeated operations of automatic hot cutting, automatic flipping, automatic clamping, pre-insertion and pressing of the comb tooth material head, thereby saving cycle operation time, using stroke planning to shorten working time, eliminating manual material picking and assembly, and operating and assembling a finished product in about 25 seconds, excluding manual loading and unloading time, making the operation cycle more stable, improving work efficiency and reducing labor costs.

7. A method for using a double-station automatic assembly mechanism for comb bead heads according to any one of claims 1 to 6: Step 1, installation of comb teeth and silicone body: First, the operator puts the comb teeth into the jig that carries the comb teeth, and then puts the comb teeth jig loaded with comb teeth on the hot-cut carrier positioning mold closest to the handling, clamping and pre-insertion module position of each hot-cut module group for clamping and fixing. Three hot-cut carrier positioning molds are arranged equidistantly in a straight line structure on each hot-cut module group, and these three hot-cut carrier positioning molds are connected as a whole by equidistant stainless steel cylinders to facilitate the horizontal movement of the whole set. At the same time, the operator puts the silicone body to be assembled with the comb teeth into the silicone body positioning and rotating mold closest to the handling, clamping and pre-insertion module position of the pre-insertion pressing module group for clamping and fixing. Similarly, the pre-insertion pressing module group is also provided with equidistant stainless steel cylinders in a straight line structure. Three silicone body positioning rotating molds are arranged, and these three silicone body positioning rotating molds are connected into one body by equidistant stainless steel cylinders, which is also convenient for the horizontal movement of the whole set. Then, turn on the start button on the touch screen, and under the action of the electric control cabinet, let the hot cutting carrier conveyor belt in each hot cutting module group operate, and at the same time, let the pre-insertion pressing carrier conveyor belt in the pre-insertion pressing module group operate, so that the hot cutting carrier positioning mold closest to the transport clamping pre-insertion module position in each hot cutting module group is conveyed to the position at the bottom of the hot cutting device under the transmission of the hot cutting carrier conveyor belt, and at the same time, let the silicone body positioning rotating mold closest to the transport clamping pre-insertion module position in the pre-insertion pressing module group be conveyed to the position at the bottom of the pressing device under the transmission of the pre-insertion pressing carrier conveyor belt; Step 2, comb teeth hot cutting material head: when the hot cutting carrier positioning mold closest to the handling clamping pre-insertion module position in each hot cutting module group is transmitted to the position below the hot cutting device under the transmission of the hot cutting carrier conveyor belt, the hot cutting carrier conveyor belt will automatically stop, so that the comb teeth fixture loaded with comb teeth in the hot cutting carrier positioning mold will be retained directly below the hot cutting device, and the hot cutting device is used to hot cut the comb teeth in the comb teeth fixture in the hot cutting carrier positioning mold, and the connecting material head of the comb teeth is hot cut, so that the original comb teeth injection molding integrated part is hot cut into each comb tooth independent individual, which is convenient for subsequent clamping and pressing. Under the action of the electric control cabinet, the hot cutting operations in the two groups of hot cutting modules are carried out together; Step 3: Comb teeth positioning and flipping: When the material head in the comb teeth fixture is cut off, the hot cutting carrier conveyor belts in the two sets of hot cutting modules will start at the same time, and the comb teeth fixtures loaded with comb teeth after cutting are transferred to the two comb teeth positioning and flipping devices at the end of each set of hot cutting modules. The two comb teeth positioning and flipping devices are mirror-image structures and are located on both sides of the hot cutting carrier conveyor belt. They are used to clamp the comb teeth after hot cutting and flip them 90 degrees. First, the flipping drive device clamps the comb teeth in the comb teeth fixture in the hot cutting carrier positioning mold with two comb teeth clamping pliers on one side of the comb teeth. Then, under the push of the lifting drive device, the comb teeth in the comb teeth fixture in the hot cutting carrier positioning mold are flipped. The flip support platform is lifted upward along the four lifting and positioning rods. The four lifting and positioning rods play a role of telescopic positioning, standardizing the moving trajectory of the flip support platform and keeping the flip support platform away from the base. Since the flip bracket is installed on the upper part of the flip support platform, as the flip support platform is lifted, the flip driving device on the flip bracket is driven to move the two comb tooth clamps on the comb tooth side to separate the already clamped comb teeth from the comb tooth fixture in the hot cutting carrier positioning mold. Then, the comb teeth clamped by the two comb tooth clamps are driven by the flip driving device to rotate upward 90°, so that the comb teeth are converted from a horizontal placement state to a vertical placement state, so as to facilitate the subsequent extraction of the comb tooth clamping device; Step 4, automatic clamping, pre-insertion and pressing of comb teeth: when the comb teeth in the comb tooth fixture in the hot-cut carrier positioning mold are turned over, the comb tooth clamping device on the transport clamping and pre-insertion mold group will extract the comb teeth that have been turned over and are in a vertical position. Then, the transport drive motor drives the transport linkage device, and the transport linkage device adopts a slideway transmission belt, so that the comb tooth clamping device connected to the transport linkage device can move horizontally along the transport linkage device. Then, the comb teeth extracted by the comb tooth clamping device are inserted into the silicone body in the silicone body positioning rotating mold on the pre-insertion and pressing mold group that is closest to the transport clamping and pre-insertion mold position. After the pre-insertion is completed once, the silicone body positioning rotating mold is driven by the pre-insertion and pressing carrier conveyor belt and is conveyed to the pressing The comb teeth after pre-insertion are pressed directly below the closing device, thereby completing one pre-insertion and pressing of the comb teeth. It is necessary to use the comb tooth clamping device to repeatedly pre-insert and press one comb tooth three times, that is, pre-insert once and press once, for a total of three times, so that the comb teeth and the silicone body are assembled more firmly; the comb tooth clamping device is used in conjunction with the pressing device, and after completing the pre-insertion and pressing operation of the current comb teeth, the comb teeth in each group of hot-cutting modules that have been flipped 90° by the comb tooth positioning flipping device are clamped and transmitted, and three pre-insertion and pressing are completed, so that the comb teeth in the comb tooth fixture in the hot-cutting carrier positioning mold at the current position in each group of hot-cutting modules and the silicone body inside the silicone body positioning rotating mold in the pre-insertion and pressing module complete the pre-insertion and pressing operation; Step 5. Removal of assembled finished products: After the comb teeth and silicone body pre-insertion and pressing of the three hot-cut carrier positioning dies on the top of each hot-cut module group and the three silicone body positioning rotating dies on the top of the pre-insertion and pressing module group are at the same horizontal line, the operator is responsible for manually taking out the silicone body finished parts with comb teeth that have been assembled in the silicone body positioning rotating dies on the top of the pre-insertion and pressing module group; Step 6, cyclic operation: while the comb teeth and silicone body at the same horizontal position of the three hot cutting carrier positioning molds on the top of each group of hot cutting modules and the three silicone body positioning rotating molds on the top of the pre-insertion and pressing modules are automatically pre-inserted and pressed, the operator can continue to put the comb teeth into the jig carrying the comb teeth, and put the comb teeth jig with comb teeth into the vacant hot cutting carrier positioning mold. Similarly, the operator can continue to put the silicone body into the vacant silicone body positioning rotating mold for subsequent pre-insertion and pressing; the operator can put the comb teeth jig loaded with comb teeth and the silicone body into the three hot cutting carrier positioning molds and the three silicone body positioning rotating molds at one time, or can place the comb teeth jig loaded with comb teeth and the silicone body while performing the pre-insertion and pressing operation.
