[0024] like Figure 1 The pressure frame shown includes a bottom frame 01 and an upper cover 02, wherein the bottom frame 01 includes a bottom wall and side walls disposed on both sides of the bottom wall and capable of being bent upwards, and the upper cover 02 is used to seal the top of the bottom frame 01. A protrusion 03 is disposed on the lower surface of the bottom wall.

[0025] like Figure 2 A tooling for the pressure frame shown in the figure includes a base plate 04 and a clamping plate 05, wherein the two clamping plates 05 are arranged opposite to each other, and the two clamping plates 05 are arranged on the surface of the base plate 04. Here, the opposite arrangement means that the two clamping plates 05 are parallel to each other. A sliding plate 06 that can slide up and down is sandwiched between the two clamping plates 05, and a clamping portion is arranged at one end of the clamping plate 05 away from the base plate 04, and the clamping portion is used to fix the bottom frame 01 and keep the bottom frame 01 in an open state. The clamping portion is located on the side where the two clamping plates 05 are close to each other. A guide plate 07 is also arranged between the clamping plate 05 and the sliding plate 06, and an inclined surface biased toward the clamping plate 05 is arranged on the upper end of the side of the guide plate 07.

[0026] In this technical solution, the bottom frame 01 is fixed in the tooling by pressing, and the side of the guide plate 07 guides the bottom frame 01 to open and is fixed by the clamping part, which prevents the bottom frame 01 from changing its opened shape. In order to prevent the side of the guide plate 07 from scratching the bottom frame 01, it can be chamfered.

[0027] The sliding up and down movement of the sliding plate 06 is achieved in the following manner: a guide column 08 is provided between the two clamping plates 05, the guide column 08 is vertically fixed on the bottom plate 04, and an elastic device 081 is sleeved on the guide column 08. The function of the guide column 08 is to guide the movement direction of the elastic device 081, and the elastic device 081 is preferably a spring. The guide column 08 is preferably a convex cylinder, one end of the spring is fixed to the guide column 08, and the other end is fixed to the sliding plate 06. Multiple sets of guide columns 08 and elastic devices 081 can be provided to facilitate the sliding plate 06 to remain horizontal and stable during the sliding process.

[0028] The upper surface of the sliding plate 06 is provided with a ridge 061, which is used to cooperate with the protrusion 03 of the bottom frame 01 to achieve positioning and fixing. The ridge 061 and the projection of the clamping plate 05 on the bottom plate 04 are perpendicular to each other.

[0029] In order to prevent foreign matter from falling between the sliding plate 06 and the bottom plate 04 when the tooling is in use, the present invention further provides a baffle 09, which is arranged on both sides of the clamping plate 05 near one end of the bottom plate 04, and has the same height as the height of the sliding plate 06 when the elastic device 081 is in a free state. The baffle is not drawn in the figure to clearly show the internal structure.

[0030] The aforementioned clamping part includes a first clamping part and a second clamping part, the first clamping part is arranged on both sides of one end of the clamping plate 05 away from the bottom plate 04, and a plurality of the second clamping parts are arranged between the two first clamping parts, and the plurality of the clamping parts are arranged at intervals. The first clamping part includes a first protrusion and a second protrusion, and the second clamping part includes two second protrusions and a first protrusion arranged between the two second protrusions, and the thickness of the first protrusion is greater than the thickness of the second protrusion. The first clamping part and the second clamping part are both arranged on the surface of the clamping plate 05, and the bottom surfaces of the first clamping part and the second clamping part form the same angle with the clamping plate 05, which is an obtuse angle. When the sliding plate 06 moves downward, as the bottom frame 01 moves downward, the two ends of the bottom frame 01 will be clamped in the clamping part; when the bottom frame 01 needs to be folded to form a "concave" shape, the two ends of the bottom frame 01 slide out from the angle, which is convenient and quick. Moreover, the interval setting distance of the clamping part should be adapted to the width of the bottom frame 01, and the clamping part also has the function of positioning and limiting. Of course, the clamping portion and the clamping plate 05 can be integrally formed as in the present embodiment, or can be fixed together in other ways.

[0031] like Figure 3-9The illustrated embodiment of a feeding mechanism for a horizontal battery pressure frame upper cover comprises a feeding mechanism 1 and a covering mechanism 2, wherein the covering mechanism 2 comprises a lifting platform 27 and a suction structure 21, wherein the suction structure 21 is used to suck the upper cover transported by the feeding mechanism and press the upper cover onto the bottom frame located on the lifting platform 27. The feeding mechanism 1 comprises a horizontally movable pushing structure 12, wherein the end of the moving path of the pushing structure 12 is located between the suction structure 21 and the lifting platform 27, wherein the distance between the suction structure 21 and the lifting platform 27 specifically refers to the vertical direction.

[0032] In the present technical solution, the feeding mechanism 1 transports the upper cover to the covering mechanism 2, so that the covering mechanism 2 can press the upper cover onto the bottom frame. The reciprocating alternating motion of the feeding mechanism 1 and the suction structure 21 can effectively save assembly time and greatly improve efficiency. Moreover, the compact installation of the feeding mechanism 1 and the covering mechanism 2 can greatly reduce the space occupied by the device.

[0033] Furthermore, the feeding mechanism 1 includes a workbench 11, and a material-dispensing opening 111 is provided on one side of the workbench 11 close to the covering mechanism 2, and a plurality of material-dispensing openings 111 are provided at intervals. The pushing structure 12 is provided below the workbench 11. A stacking rack 112 is provided above the material-dispensing opening 111, and the stacking rack 112 includes a plurality of longitudinal stacking channels 113, and a detection hole is provided below the side wall of the stacking channel 113, and a detection hole 114 is preferably provided horizontally through the stacking rack 112, and a detection element 115 is provided in the detection hole.

[0034] Specifically, the stacked upper covers are prevented from being placed in the stacking channel 113, and the pushing structure 12 is used to move the upper covers. The setting of the multiple material-moving ports 111 can move multiple upper covers at one time, which speeds up the assembly efficiency. The function of the detection element 115 is to detect the number of upper covers in the stacking channel 113. In this embodiment, the detection element 115 uses an infrared distance sensor; different upper cover residual materials can be set according to the different heights of the detection hole in the stacking rack 112. In this embodiment, the detection hole is set above the upper cover of the lowest layer. When there are a sufficient number of upper covers in the stacking channel 113, the infrared distance sensor is blocked by the upper cover and cannot penetrate the stacking rack 112, and the infrared distance sensor generates a first signal; when there is only one upper cover in each stacking channel 113, the infrared distance sensor cannot be blocked, and the infrared distance sensor generates a second signal. The detection element 115 is connected to the PLC signal, and the PLC is also connected to a speaker. When the PLC receives the first signal, there is no action instruction; when the PLC receives the second signal, the PLC sends an instruction to the speaker to remind the worker to load the cover.

[0035] In this solution, in order to achieve work preparation, multiple stacking channels 113 facilitate multiple pushes of the pushing structure 12, thereby improving efficiency. In addition, the setting of the detection element 115 can automatically detect the remaining amount of the upper cover without the need for personnel supervision, thereby greatly liberating manpower.

[0036] Further, the pushing structure 12 includes a toggle frame 121, which is arranged below the workbench 11. Two bearing supports 123 are arranged on the toggle frame 121. The two bearing supports 123 are rotatably connected to a rotating shaft 124. A push block 125 is arranged on the rotating shaft 124, and a plurality of push blocks 125 are arranged at intervals. The upper end of the push block 125 can partially exceed the material-dispensing opening 111, and the push block 125 is fixedly connected to the rotating shaft 124. The toggle frame 121 also includes a driver, which is used to drive the rotating shaft 124 to rotate. The driver includes a driving block 1261 and a second cylinder 1262. The driving block 1261 is fixedly arranged on the rotating shaft 124, the second cylinder 1262 is arranged below the workbench 11, and the movable end of the second cylinder 1262 is hinged to the driving block 1261. The toggle frame 121 also includes a first cylinder 122, which is used to push the toggle frame 121 to move horizontally. The first cylinder 122 is disposed below the workbench 11. The pushing structure 12 further includes a sliding frame 127, which is slidably connected to the bottom of the workbench 11 and is used to support the upper cover pushed out by the pushing block 125. The sliding frame 127 includes a supporting platform 1271, which is slidably connected to the bottom of the workbench 11. The supporting platform 1271 is also connected to a third cylinder 1272 that pushes the supporting platform 1271 to move horizontally, and the third cylinder 1272 is fixed to the bottom of the workbench 11.

[0037] Specifically, the support platform 1271 is slidably connected to the workbench 11 through a slide rail, two slide rails are arranged on both sides of the support platform 1271, and the third cylinder 1272 is arranged in the middle of the support platform 1271. The slide rail not only reduces friction and facilitates movement, but also has a limiting function to prevent the support platform 1271 from twisting during movement. Preferably, the push block 125 selects a rectangular block, and a chamfer is performed on one side of the workbench 11 far from the upper end of the push block 125. Preferably, two push blocks 125 are allowed to move in each material dispensing port 111, and similarly, the upper cover is prevented from twisting during movement. Preferably, the drive block 1261 selects a shape that is approximately conical, and the projection of the drive block 1261 and the push block 125 on the side forms an angle, and the preferred angle is a right angle. The second cylinder 1262 is vertically arranged below the workbench 11, and the second cylinder 1262 is hinged to the drive block 1261. When the second cylinder 1262 is in motion, it drives the driving block 1261. At this time, the driving block 1261 rotates with the rotating shaft 124, driving the push block 125 to rotate. The second cylinder 1262 and the third cylinder 1272 are connected to the aforementioned PLC signal.

[0038] In the present technical solution, in the initial state, the push block 125 remains in a vertical state, and the supporting platform 1271 is in contact with the workbench 11. As the first cylinder 122 extends, the push block 125 pushes the upper cover to the workbench 11 and is supported by the supporting platform 1271. The upper cover located in the stacking channel 113 falls due to the action of gravity. When the first cylinder 122 is shortened, the second cylinder 1262 is activated at the same time, and the push block 125 rotates to a horizontal state. When the first cylinder 122 is shortened to below the workbench 11, the second cylinder 1262 is activated, so that the push block 125 is changed to a vertical state here, in preparation for the next push. After being supported by the supporting platform 1271, the upper cover is connected to the supporting platform 1271 by the third cylinder 1272 and pushed to the covering mechanism 2, in preparation for the next step. From the previous description, we can know that chamfering the push block 125 not only prevents the sharp push block 125 from scratching the upper cover, but more importantly, it will not interfere with the upper cover during the rotation of the push block 125. Not chamfering the other side of the push block 125 makes it easier for the push block 125 to push the upper cover out.

[0039] Furthermore, the surface of the support platform 1271 is provided with a groove 1273 of the same shape as the upper cover, and the support platform 1271 is at the same height as the workbench 11. When the support platform 1271 supports the upper cover, it is convenient for the upper cover to slide into the groove 1273, and it can also prevent the upper cover from falling during the movement of the support platform 1271.

[0040] The aforementioned capping mechanism 2 includes a support body 22. The aforementioned suction structure 21 is arranged at the top of the support body 22, and the suction structure 21 includes a fourth cylinder 23, the fourth cylinder 23 is arranged at the top of the support body 22, and a pressing plate 25 is arranged at the movable end of the fourth cylinder 23, and the pressing plate 25 is provided with a plurality of vacuum suction nozzles 26 for sucking the upper cover, and a lifting platform 27 is arranged below the vacuum suction nozzle 26, and the lifting platform 27 is arranged in the middle of the support body 22, and a mounting portion for mounting tooling is arranged on the surface of the lifting platform 27.

[0041] Specifically, the suction structure 21 is located above the support platform 1271, and is used to suck the upper cover on the support platform 1271 and press it onto the bottom frame. Preferably, clamping plates are provided on both sides of the pressing plate 25, and the two clamping plates clamp the pressing plate 25 at the central position, and the clamping plates can prevent the pressing plate 25 from being pressed down too much.

[0042] Furthermore, push handles 271 for horizontal pressing tooling are provided on both sides of the lifting platform 27. The push handles 271 are provided on the sides of the support body 22. The push handles 271 include a fifth cylinder 2711 and a pressing block 2712. The fixed end of the fifth cylinder 2711 is provided on the side of the support body 22, and the pressing block 2712 is provided on the movable end of the fifth cylinder 2711. The pressing block 2712 passes through the tooling and abuts against the bottom frame.

[0043] In the present technical solution, the function of the push handle 271 is to press the bottom frame installed in the tooling in the horizontal direction so that the upper cover and the bottom frame are firmly fixed.

[0044] Furthermore, a sixth cylinder 28 is provided on the lower surface of the lifting platform 27 , and a fixed end of the sixth cylinder 28 is provided therebehind, and a movable end is connected to the lower surface of the lifting platform 27 .

[0045] In the above technical solution, the fourth cylinder 23, the fifth cylinder 2711, the sixth cylinder 28, and the first cylinder 122 are all connected to the PLC by signals and controlled by the PLC. In addition, in this embodiment, the cylinder and the first cylinder 122 can use other parts with a stroke pushing function that can be controlled by electronic components.

[0046] In this embodiment, after the vacuum nozzle 26 sucks the upper cover from the supporting platform 1271, the supporting platform 1271 is returned to the workbench 11, and the fourth cylinder 23 pushes the pressing plate 25 to move downward, so that the upper cover and the bottom frame are in contact and pressed together. While the upper cover and the bottom frame are pressed together, the fifth cylinder 2711 pushes the pressing block 2712 to complete the locking, and the upper cover and the bottom frame are firmly fixed.

[0047] The advantages of the present invention are as follows: First, automated and batch loading can greatly improve production efficiency; second, the detection element 115 is used to automatically detect the upper cover remainder in the stacking channel 113, freeing up manpower; third, the covering mechanism 2 can perfectly press the upper cover and the bottom frame located in the tooling to achieve the locking of the two, without the need for secondary processing of the pressure frame at a later stage, and the finished product efficiency is high and the failure rate is low.

[0048] The above description is only a preferred embodiment of the present invention and does not constitute a limitation on the protection scope of the present invention.
