Description

Technical Field

[0001] The present invention relates to the technical field of opening and closing equipment, in particular to a flip cover mechanism and a linked box opening device. Background Art

[0002] As the name suggests, a packaging box is a box used to package products and is now widely used in various industries. Generally, in order to facilitate opening and closing, the sealing part of the packaging box is composed of two packaging leaves. When using the packaging box, you need to open the two packaging leaves, then place the product into the cavity of the packaging box, and finally buckle the two packaging boxes to the two packaging leaves to seal them, thereby completing the product packaging.

[0003] However, the opening process of the packaging leaf is not a simple linear motion. After the vacuum adsorption mechanism is used to adsorb the packaging leaf to a fixed position, the lifting mechanism, the rotation mechanism, and the translation mechanism need to cooperate to complete an arc motion trajectory to complete the flipping action. In order to solve this problem, the existing technology uses a multi-axis robotic arm to simulate the movement of a human arm to complete the grasping and flipping actions. However, opening the packaging box is just an ordinary process on the production line, which only requires repeating a mechanical action. The multi-axis robotic arm has precise displacement and control, but it is expensive. It is a waste of resources and costs to achieve a simple box opening action. Therefore, a simpler flipping mechanism is needed.

[0004] Moreover, it is useless to simply open the packaging leaves of the packaging box. During the actual packaging process, it is necessary to continuously ensure that the packaging leaves are in an open state. This requires the flip mechanism to continuously act on the packaging leaves during the packaging process. However, in the actual production process, this idea is unrealistic, because the flip mechanism needs to apply force from the top of the packaging box to complete the flipping action of the packaging leaves. At the same time, in the process of placing the product into the packaging box, the boxing mechanism also needs to complete the boxing action from the top of the packaging box. These two mechanisms will interfere with each other in the packaging box. Therefore, in order to complete the box opening action and meet the assembly requirements, it is not enough to just set up a flip mechanism. It is necessary to provide a box opening device that can cooperate with the flip mechanism. Summary of the Invention

[0005] To this end, the technical problem to be solved by the present invention is to overcome the problems existing in the packaging box opening equipment in the prior art and the problem that the flip mechanism cannot realize the box opening action alone, and provide a flip mechanism and a linkage box opening device. The flip mechanism is set to realize the box opening action of the packaging box, and the flip mechanism is set to cooperate with the pin dialing mechanism to ensure that the packaging box is in an open state, and does not interfere with the box loading mechanism and does not affect the box loading action of the box loading mechanism.

[0006] In order to solve the above technical problems, the present invention provides a flip cover mechanism, comprising:

[0007] Mounting plate;

[0008] A flip cover drive assembly is arranged on the mounting plate;

[0009] A slider connected to the flip cover drive assembly, wherein the flip cover drive assembly drives the slider to reciprocate along a first direction on the mounting plate;

[0010] a suction cup connected to the slider, the suction cup extending along the second direction, the first direction and the second direction both being arranged on the plane where the mounting plate is located, and the first direction and the second direction being perpendicular, the slider being provided with a slide groove extending along the second direction, the suction cup being slidably hinged in the slide groove via a pin, and the pin being capable of moving in the slide groove;

[0011] Wherein: the suction cup abuts against the blade to be flipped, the suction cup is pushed by the reaction force to move the pin to the high position of the slide groove, the suction cup absorbs the blade to be flipped, and the flip cover driving assembly drives the suction cup to move along the first direction. During the movement, the suction cup rotates relative to the slider through the pin, and at the same time, the pin moves from the high position of the slide groove to the low position of the slide groove, and the blade to be flipped is driven to flip a certain angle.

[0012] In one embodiment of the present invention, the flip drive assembly includes:

[0013] a flip cover driving source, applying a driving force in a second direction;

[0014] A cam, arranged at an output end of the flip cover driving source;

[0015] a steering block, disposed in the direction of force applied by the flip cover drive source, the steering block being connected to the slider, the steering block being provided with an inclined surface for sliding of the cam, the flip cover drive source driving the cam to slide along the inclined surface, converting the driving force applied in the second direction into a sliding force that pushes the slider to slide in the first direction;

[0016] The first elastic member acts on the slider. Before the flip drive source applies force to the steering block, the first elastic member is not subjected to force. When the flip drive source applies force to push the slider to slide, the first elastic member applies a force opposite to the sliding direction of the slider. When the flip drive source stops applying force, the first elastic member drives the slider to reset.

[0017] In one embodiment of the present invention, the flip drive assembly further includes:

[0018] a stopper connected to the output end of the flip cover driving source;

[0019] The upper limit block and the lower limit block are arranged on the upper and lower sides of the block along the moving direction of the output end of the flip cover drive source. The block abuts against the upper limit block and the lower limit block respectively to limit the moving position of the output end of the flip cover drive source, thereby limiting the flip angle of the blade to be flipped.

[0020] In one embodiment of the present invention, the slider includes: a first slider and a second slider, which are driven by the flip-cover driving assembly to slide synchronously toward or in opposite directions along a first direction, and the suction cup includes: a first suction cup and a second suction cup, the first suction cup is connected to the first slider, and the second suction cup is connected to the second slider, the first suction cup and the second suction cup respectively adsorb two blades to be flipped, and the first suction cup and the second suction cup drive the two blades to be flipped to rotate in two directions.

[0021] In one embodiment of the present invention, a leaf spring extending toward the suction cup is provided on the side of the slider, and the leaf spring limits the suction cup from always extending along the second direction when no external force is applied.

[0022] In order to solve the above technical problems, the present invention also provides a linkage box opening device, comprising the above flip cover mechanism, and further comprising: a pin setting mechanism, wherein the pin setting mechanism comprises:

[0023] a slide module for applying a driving force along a third direction, wherein the third direction is perpendicular to the mounting plate;

[0024] A needle-setting drive assembly is provided on the slide module, and the needle-setting drive assembly moves back and forth along the third direction driven by the slide module;

[0025] A setting needle, connected to the setting needle driving assembly and driven by the setting needle driving assembly to move along a first direction;

[0026] Wherein: after the flip cover mechanism drives the blade to be flipped to flip a certain angle, the slide module in the needle setting mechanism drives the setting needle to be inserted from the third direction to the bottom of the blade to be flipped, and the needle setting drive assembly drives the setting needle to move along the first direction and press against the blade to be flipped, and continues to move to push the blade to be flipped to unfold outward.

[0027] In one embodiment of the present invention, the needle setting drive assembly includes:

[0028] A needle-setting drive source is provided on the slide module and applies a driving force along a third direction;

[0029] The mounting platform is connected to the needle-setting drive source and is driven by the needle-setting drive source to reciprocate along the third direction. A limiting slide groove is provided on the mounting platform, and the limiting slide groove is inclined relative to the third direction.

[0030] A setting needle adapter block, one end of which is slidably disposed in the limiting sliding groove and the other end of which is connected to the setting needle, wherein the setting needle adapter block converts the driving force applied in the third direction into a sliding force that drives the setting needle to slide in the first direction;

[0031] The second elastic member acts on the needle shifting adapter block. Before the needle shifting drive source applies force to the needle shifting adapter block, the second elastic member is not subjected to force. When the needle shifting drive source applies force to drive the needle shifting adapter block to move, the second elastic member applies a force opposite to the moving direction of the needle shifting adapter block. When the needle shifting drive source stops applying force, the second elastic member drives the needle shifting adapter block to reset.

[0032] In one embodiment of the present invention, the needle setting drive assembly further includes: a limit baffle, which is arranged on the moving path of the mounting platform. When the needle setting drive source drives the mounting platform to abut against the limit baffle, the needle pushes the blade to be flipped to open to the maximum angle.

[0033] In one embodiment of the present invention, it further comprises:

[0034] The carrier is used to clamp, position and drive the product to be opened, and the needle-moving mechanism is arranged on the side of the carrier along the third direction;

[0035] The transfer mechanism is connected to the flip mechanism, and the transfer mechanism drives the flip mechanism to move above the carrier.

[0036] In one embodiment of the present invention, a plurality of groups of flipping mechanisms are provided on the transfer mechanism, and a plurality of groups of needle setting mechanisms are provided corresponding to the flipping mechanisms.

[0037] The above technical solution of the present invention has the following advantages over the prior art:

[0038] The flip cover mechanism described in the present invention sets the suction cup in the sliding groove of the slider through the pin, so that the suction cup can not only slide relative to the slider, but also rotate axially relative to the slider. In actual use, the suction cup is used to abut the blade to be flipped (i.e., the packaging blade), and the suction cup is pushed by the reaction force to move the pin to the high position of the slide groove. The suction cup adsorbs the blade to be flipped, and the flip cover driving component drives the suction cup to move along the first direction. During the movement, the suction cup rotates relative to the slider through the pin. At the same time, the pin moves from the high position of the slide groove to the low position of the slide groove. This series of actions completes an arc motion trajectory, so that the blade to be flipped is driven to flip a certain angle. The flip cover mechanism of the present invention only requires the flip cover driving component to provide a linear driving force. Compared with the existing box opening equipment, the rotating mechanism and the lifting mechanism are omitted. Only the translation mechanism is set to complete the box opening action equivalent to that of a multi-axis robotic arm, saving equipment cost.

[0039] The combined box opening device described in the present invention is provided with a pin-shifting mechanism to cooperate with the above-mentioned flip-cover mechanism. After the flip-cover mechanism completes the adsorption and flipping action, it is inserted from the side under the blade to be flipped, and unfolded in the flipping direction of the blade to be flipped, pressing and fixing the blade to be flipped, and continuously pushing the blade to be flipped to unfold and be in the unfolded position. At this time, the flip-cover mechanism can be controlled to reset so that the flip-cover mechanism no longer acts on the blade to be flipped, and assembly space can be reserved above the blade to be flipped. The box loading mechanism can be used to complete the box loading action on the blade to be flipped, and the pin-shifting mechanism continuously presses and limits the blade to be flipped, so that the blade to be flipped is in the box opening state, and does not interfere with the box loading mechanism, and does not affect the box loading action of the box loading mechanism.

[0055] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. Example 1

[0056] Reference Figure 1As shown, the present invention discloses a flip mechanism, comprising: a mounting plate 11, a flip drive assembly 12, a slider 13 and a suction cup 14, wherein: the mounting plate 11 is vertically arranged in the space, the horizontal direction of the plane where the mounting plate 11 is located is a first direction, and the vertical direction of the plane where the mounting plate 11 is located is a second direction, the flip drive assembly 12 and the slider 13 are both arranged on the plane of the mounting plate 11, the slider 13 is connected to the driving end of the flip drive assembly 12, the flip drive assembly 12 drives the slider 13 to reciprocate on the mounting plate 11 along the first direction, the suction cup 14 is connected to the slider 13, and the suction cup 14 is extended along the second direction. In this embodiment, the suction cup 14 is a hollow adsorption head, which is used to adsorb the blades to be flipped, that is, the packaging blades of the packaging box, and the flip drive assembly 12 drives the adsorbed blades to be flipped to complete the flipping action, thereby realizing the opening action of the packaging box.

[0057] As mentioned above, since the opening process of the packaging leaf is not a simple linear motion, after the suction cup 14 is adsorbed to the fixed position of the leaf to be flipped, it is necessary to use the lifting mechanism, the rotation mechanism and the translation mechanism to complete an arc motion trajectory before the flipping action can be completed. In order to solve this problem, the present invention refers to Figure 2 and Figure 3 As shown, a slide groove 15 extending along the second direction is formed on the slider 13, and the suction cup 14 is slidably hinged in the slide groove 15 via a pin 16. The pin 16 can move in the slide groove 15. Therefore, the suction cup 14 in the present invention can not only slide relative to the slider 13, but also rotate axially relative to the slider 13;

[0058] Reference Figure 2 As shown, in actual use, the suction cup 14 is used to move from the upper side of the blade to be flipped toward the blade to be flipped. When the suction cup 14 abuts against the blade to be flipped, the suction cup 14 is continuously driven to move. The suction cup 14 is pushed by the reaction force to move the pin 16 to the high position of the chute 15. The chute 15 restricts the movement of the pin 16, thereby restricting the suction cup 14 from continuing to move. At this time, the suction cup 14 is turned on, that is, the blade to be flipped is vacuum-adsorbed; refer to Figure 3 As shown, the flip-cover drive assembly 12 drives the suction cup 14 to move in the first direction. During the movement, the suction cup 14 rotates relative to the slider 13 through the pin. At the same time, the pin moves from the high position of the slide groove 15 to the low position of the slide groove 15. This series of actions completes an arc motion trajectory, so that the blade to be flipped is driven to flip a certain angle. The flip-cover mechanism of the present invention only requires the flip-cover drive assembly 12 to provide a linear driving force. Compared with the existing box opening equipment, the rotating mechanism and the lifting mechanism are omitted. Only the translation mechanism is set to complete the box opening action equivalent to a multi-axis robotic arm, saving equipment costs.

[0059] In actual use, under normal circumstances, the packaging box has two leaves to be turned over. Figure 4 As shown, in this embodiment, the slider 13 is provided to include: a first slider 131 and a second slider 132, and the first slider 131 and the second slider 132 are driven by the flip-cover driving component 12 to slide synchronously toward or in opposite directions along a first direction, and the suction cup 14 includes: a first suction cup 141 and a second suction cup 142, the first suction cup 141 is connected to the first slider 131, and the second suction cup 142 is connected to the second slider 132, the first suction cup 141 and the second suction cup 142 respectively adsorb two blades to be flipped, and the first suction cup 141 and the second suction cup 142 drive the two blades to be flipped to rotate in two directions, so that the flip mechanism described in the present invention can realize the synchronous opening action of the two blades to be flipped through a flip-cover driving component 12.

[0060] Specifically, in some special packaging boxes, there may be multiple openings in the packaging box, refer to Figure 1 As shown, in order to solve this problem, the slider 13 is provided with multiple branches, and a suction cup 14 can be provided on each minute of the slider 13, so that multiple suction cups 14 can be provided according to the number of openings of the packaging box, so that the synchronous opening action of multiple openings can be realized, which can match the use of packaging boxes with multiple openings.

[0061] Reference Figure 4 As shown, in this embodiment, in order to set the flip cover drive component 12 to provide a sliding force that pushes the slider 13 along the first direction, the flip cover drive component 12 is specifically provided to include: a flip cover drive source 121, a cam 122, a steering block 123 and a first elastic member 124, wherein: in this embodiment, the vertical space on the mounting plate 11 is relatively abundant, so the flip cover drive source 121 is provided to apply a driving force in the second direction, for example: a cylinder drive source, for this purpose it is necessary to convert the driving force applied in the second direction into the first direction, so the cam 122 and the steering block 123 are provided. 23, the cam 122 is arranged at the output end of the flip cover drive source 121, the steering block 123 is arranged in the force application direction of the flip cover drive source 121, that is, it is arranged below the cam 122, the steering block 123 is connected to the slider 13, and the steering block 123 is provided with an inclined surface for the cam 122 to slide. The flip cover drive source 121 drives the cam 122 to slide along the inclined surface, converting the driving force applied in the second direction into a sliding force that pushes the slider 13 to slide in the first direction, thereby realizing the steering of power;

[0062] In actual use, power is also required for resetting, that is, when the flip-cover drive source 121 is reset, the slider 13 needs to be driven to reset. However, in this embodiment, the cam 122 and the steering block 123 are coordinated, and the resetting power of the flip-cover drive source 121 cannot be transmitted to the slider 13. Therefore, in this embodiment, a first elastic member 124 is also provided, and the first elastic member 124 acts on the slider 13. Before the flip-cover drive source 121 applies force to the steering block 123, the first elastic member 124 is not subjected to force. When the flip-cover drive source 121 applies force to push the slider 13 to slide, the first elastic member 124 applies a force opposite to the sliding direction of the slider 13. When the flip-cover drive source 121 stops applying force, the first elastic member 124 drives the slider 13 to reset.

[0063] In actual use, it is necessary to limit the flip angle of the blade to be flipped. In this embodiment, the flip cover drive source 121 is the only power output unit. As long as the flip cover drive source 121 drives the stroke of the slider 13, the flip angle of the blade to be flipped can be controlled. Therefore, referring to Figure 4 As shown, the flip-cover drive assembly 12 also includes: a stopper 125, an upper limit block 126 and a lower limit block 127. The stopper 125 is connected to the output end of the flip-cover drive source 121. The upper limit block 126 and the lower limit block 127 are arranged on the upper and lower sides of the stopper 125 along the moving direction of the output end of the flip-cover drive source 121. The stopper 125 abuts against the upper limit block 126 and the lower limit block 127 respectively to limit the moving position of the output end of the flip-cover drive source 121, thereby limiting the flipping angle of the blade to be flipped.

[0064] In this embodiment, since the suction cup 14 is movably connected to the slider 13 using the pin 16, in order to prevent the suction cup 14 from swinging at will during actual use, Figure 2 As shown, a leaf spring 17 extending toward the suction cup 14 is provided on the side of the slider 13. The leaf spring 17 limits the suction cup 14 to always extend along the second direction when not subject to external force. The suction cup 14 is elastically supported by the leaf spring 17. When not subject to force, the leaf spring 17 can limit the swing of the suction cup 14, ensuring that the suction cup 14 can be accurately adsorbed at the designated position of the blade to be flipped during actual use. Example 2

[0065] As mentioned above, it is useless to simply open the packaging leaves of the packaging box. In the actual packaging process, it is necessary to continuously ensure that the packaging leaves are in an open state. This requires the flip mechanism to continuously act on the packaging leaves during the packaging process. However, in the actual production process, this idea is unrealistic, because the flip mechanism needs to apply force from the top of the packaging box to complete the flipping action of the packaging leaves. At the same time, in the process of placing the product into the packaging box, the packaging mechanism also needs to complete the packaging action from the top of the packaging box. These two mechanisms will interfere with each other in the packaging box. Therefore, in order to complete the box opening action and meet the assembly requirements, it is not enough to just set up the flip mechanism. In order to solve this problem, refer to Figure 5 As shown, this embodiment provides a linked box opening device, including the flip cover mechanism 1 described in the above embodiment 1, and also includes a pin setting mechanism 2. The pin setting mechanism 2 cooperates with the flip cover mechanism 1 to ensure that the packaging box is in an open box state, and does not interfere with the box loading mechanism and does not affect the box loading action of the box loading mechanism.

[0066] Specifically, refer to Figure 6 As shown, the needle-setting mechanism 2 includes: a slide module 21, a needle-setting drive assembly 22 and a needle-setting 23, wherein: the slide module 21 applies a driving force along a third direction, the third direction is perpendicular to the mounting plate 11, the needle-setting drive assembly 22 is arranged on the slide module 21, the needle-setting drive assembly 22 reciprocates along the third direction under the drive of the slide module 21, the needle-setting drive assembly 22 is connected to the needle-setting drive assembly 22, and is driven by the needle-setting drive assembly 22 to move along the first direction. When actually used, after the flip mechanism 1 drives the blade to be flipped to flip a certain angle, the slide module 21 in the needle-setting mechanism 2 drives the needle-setting 23 from The third direction is inserted under the blade to be flipped, and the needle driving assembly 22 drives the needle 23 to move along the first direction and press on the blade to be flipped, and continues to move to push the blade to be flipped to unfold outward, presses and fixes the blade to be flipped, and continues to push the blade to be flipped to unfold and be in the unfolded position. At this time, the flip cover mechanism 1 can be controlled to reset so that the flip cover mechanism 1 no longer acts on the blade to be flipped, and assembly space can be reserved above the blade to be flipped. The boxing mechanism can be used to complete the boxing action on the blade to be flipped, and the needle mechanism 2 continues to press and limit the blade to be flipped, so that the blade to be flipped is in the open box state without interfering with the boxing mechanism and affecting the boxing action of the boxing mechanism.

[0067] Reference Figure 7As shown, in this embodiment, the needle-setting drive assembly 22 includes: a needle-setting drive source 221, a mounting platform 222, a needle-setting adapter block 223, and a second elastic member 224, wherein: the purpose of the needle-setting drive source 221 is to drive the needle-setting 23 to move along the first direction. However, in actual production, due to the small size of the packaging box, there is not enough space to set the needle-setting drive source 221 along the first direction to directly drive the movement of the needle-setting 23. Therefore, the needle-setting drive source 221 is set on the slide module 21, and the setting of the needle-setting drive source 221 can apply a driving force along the third direction. For example: a cylinder driving source, the mounting platform 222 is connected to the output end of the needle driving source 221, and the mounting platform 222 is driven by the needle driving source 221 to reciprocate along the third direction. A limiting slide groove 2221 is provided on the mounting platform 222, and the limiting slide groove 2221 is inclined relative to the third direction. One end of the needle adapter block 223 is slidably arranged in the limiting slide groove 2221, and the moving trajectory of the needle adapter block 223 is limited by the limiting slide groove 2221, and the other end is connected to the needle 23. When the needle driving source 221 drives the mounting platform 222 to move in the third direction, the needle adapter block 223 can only move along the limiting slide groove 2221, so that the driving force applied along the third direction can be converted into a sliding force that drives the needle 23 to slide along the first direction, thereby realizing the steering of power;

[0068] In actual use, power is required for resetting, that is, when the needle-setting drive source 221 is reset, the needle-setting adapter block 223 needs to be driven to reset. However, in this embodiment, the needle-setting drive source 221 acts on the mounting platform 222. Therefore, a second elastic member 224 is provided, and the second elastic member 224 acts on the needle-setting adapter block 223. Before the needle-setting drive source 221 applies force to the needle-setting adapter block 223, the second elastic member 224 is not subjected to force. When the needle-setting drive source 221 applies force to drive the needle-setting adapter block 223 to move, the second elastic member 224 applies a force opposite to the moving direction of the needle-setting adapter block 223. When the needle-setting drive source 221 stops applying force, the second elastic member 224 drives the needle-setting adapter block 223 to reset.

[0069] As described in Example 1, generally, the packaging box has two leaves to be turned over. Figure 7 As shown, in this embodiment, two limiting slide grooves 2221 are provided on the mounting platform 222, and two shifting pin adapter blocks 223 are also provided. Each of the shifting pin adapter blocks 223 is connected to a shifting pin 23, namely a first shifting pin 231 and a second shifting pin 232. When the shifting pin driving source 221 drives the mounting platform 222 to move, the first shifting pin 231 and the second shifting pin 232 move in two directions, thereby supporting and fixing the two leaves to be flipped on the packaging box.

[0070] As described in Example 1, in some special packaging boxes, there may be multiple openings in the packaging box. Figure 7 As shown, in order to solve this problem, a group of limiting slides 2221 are opened on the mounting platform 222, and each group of limiting slides 2221 includes two corresponding limiting slides 2221. Similarly, multiple groups of pin adapter blocks 223 are provided, and each group of pin adapter blocks 223 includes two pin adapter blocks 223. Each pin adapter block 223 is provided with a pin 23, so that the synchronous opening action of multiple openings can be realized, which can match the use of packaging boxes with multiple openings.

[0071] Reference Figure 5 As shown, the linked box opening device described in this embodiment also includes a carrier 3 and a transfer mechanism 4, wherein: the carrier 3 is used to clamp, position and drive the product to be opened, the needle mechanism 2 is arranged on the side of the carrier 3 along the third direction, and the transfer mechanism 4 is connected to the flip mechanism 1, and the transfer mechanism 4 drives the flip mechanism 1 to move to the top of the carrier 3.

[0072] Reference Figure 8 As shown, the carrier 3 includes: a carrier placement platform 31 and a carrier 32 arranged on the carrier placement platform 31, a product accommodating groove 321 is arranged on the carrier 32, and the product accommodating groove 321 has an opening. The product can be inserted into the product accommodating groove 321 from the opening and protrude from the product accommodating groove 321, and a clamping arm 312 is arranged on the carrier placement platform 31, and the clamping arm 312 can slide and press on the product to press and fix the product in the product accommodating groove 321.

[0073] In actual use, it is necessary to limit the tilting angle of the blade to be tilted. In this embodiment, the needle-setting drive source 221 serves as the sole power output unit. By controlling the travel of the mounting platform 222 driven by the needle-setting drive source 221, the tilting angle of the blade to be tilted can be controlled. Therefore, the needle-setting drive assembly 22 also includes a limit baffle 24 disposed in the movement path of the mounting platform 222. When the needle-setting drive source 221 drives the mounting platform 222 to abut against the limit baffle 24, the needle-setting drive 23 pushes the blade to be tilted to open to its maximum angle. In this embodiment, the clamping arm 312 is disposed in the movement path of the mounting platform 222, and therefore, the limit baffle 24 is also disposed on the clamping arm 312.

[0074] Reference Figure 9As shown, the transfer mechanism 4 is actually a lifting mechanism, and its purpose is to drive the flip mechanism 1 to adsorb the blades to be flipped from above the product. In this embodiment, the transfer mechanism 4 is provided to include a linear module 41, a linear guide rail 42 and a supporting platform 43. The linear module 41 drives the supporting platform 43 to slide along the linear guide rail 42, and the flip mechanism 1 is fixedly installed on the supporting platform 43.

[0075] Specifically, the transfer mechanism 4 also includes a sensing sheet 44 arranged on the supporting platform 43 and a photoelectric sensor 45 arranged on the linear module 41. The sensing sheet 44 cooperates with the photoelectric sensor 45 to limit the movement position of the supporting platform 43, thereby ensuring that the suction cup 14 in the flip mechanism 1 can accurately be adsorbed on the flip blade of the product.

[0076] Specifically, multiple sets of flipping mechanisms 1 are provided on the carrying platform 43 of the transfer mechanism 4, and multiple sets of needle-shifting mechanisms 2 are provided corresponding to the flipping mechanisms 1, which can synchronously complete the opening action of multiple products, further improving the working efficiency of the equipment.
