Description

Technical Field

[0001] This invention relates to the field of battery production, and more specifically to a welding strip processing device. Background Technology

[0002] The front side of the inter-branch (IBC) solar cell has no main grid lines; both the positive and negative electrode arrays are located on the back side of the cell, thereby reducing shading and improving the light conversion efficiency of the cell.

[0003] like Figure 1 The back-mounted battery cell 200 shown has a first electrode (such as a positive electrode) and a second electrode (such as a negative electrode) with opposite polarities on its back side. The first electrodes are arranged in rows to form at least two rows of first electrode rows 201, and the second electrodes are arranged in rows to form at least two rows of second electrode rows 202. The first electrode rows 201 and the second electrode rows 202 are arranged alternately.

[0004] like Figure 2 As shown, the back-mounted solar cells are welded into strings as follows: N solar cells 200 (4 in the figure) are laid out sequentially with their backs facing up, and the polarities of the electrode arrays of adjacent solar cells on the same straight line are opposite. N+1 (5 in the figure) solder ribbon groups are used to weld the N solar cells 200 into strings, wherein the first solder ribbon group (the 1st, 3rd, and 5th solder ribbon groups in the figure) and the second solder ribbon group (the 2nd and 4th solder ribbon groups in the figure) are laid out alternately.

[0005] In the traditional back-connected battery string welding process, in order to achieve staggered placement of the first and second welding strip groups, the welding strip traction mechanism needs to alternately pull and obtain the first and second welding strip groups from the welding strip supply station, and then lay the first and second welding strip groups alternately onto the battery cells.

[0006] Traditional back-connected battery string welding process has low solder strip processing efficiency, which ultimately affects the production efficiency of battery strings. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides a solder strip processing device, which adopts the following technical solution:

[0008] A welding strip processing device is used to process multiple welding strips extending along a first horizontal direction to obtain several first welding strip groups and several second welding strip groups. The welding strip processing device includes a welding strip traction mechanism and a welding strip processing mechanism, wherein:

[0010] The welding strip processing mechanism is used for staggering all the odd-numbered welding strips and all the even-numbered welding strips in the first horizontal direction by a predetermined distance, and alternately cutting all the odd-numbered welding strips and all the even-numbered welding strips to obtain a plurality of first welding strip groups and a plurality of second welding strip groups;

[0011] The welding strip processing mechanism is further used for adjusting the interval between each first welding strip group and the interval between each second welding strip group to a first predetermined interval.

[0019] Through cooperation of the first solder strip clamping assembly, the second solder strip clamping assembly, the first solder strip cutter and the second solder strip cutter, the solder strip processing mechanism realizes staggered processing between the first solder strip groups and the second solder strip groups, and adjusts the spacing between each first solder strip group and the spacing between each second solder strip group to a predetermined value.

[0067] In order to make the above-mentioned objectives, characteristics and advantages of the present application more apparent, further detailed description will be given below in combination with the drawings and specific embodiments.

[0068] In order to realize the staggered laying of the first solder strip group and the second solder strip group, the conventional back contact type battery piece welding equipment needs to be provided with two solder strip material roll groups, each of which includes a plurality of solder strip material rolls. The solder strip traction mechanism alternately tracts and obtains the first solder strip group and the second solder strip group from the two solder strip material roll groups, and lays the first solder strip group and the second solder strip group on the battery piece in a staggered manner.

[0069] The conventional back contact type battery piece welding equipment has low solder strip processing efficiency, which finally affects the production efficiency of the battery string.

[0070] In view of this, the present application provides a solder strip processing device which can realize simultaneous feeding of the first solder strip group and the second solder strip group, traction and processing of the solder strip required for an entire battery string at one time, thereby significantly improving the solder strip processing efficiency.

[0071] As shown in Figure 3 The solder strip processing device provided by the present application includes a solder strip traction mechanism 10 and a solder strip processing mechanism 20, wherein:

[0072] The solder strip traction mechanism 20 is used to tract a plurality of solder strips to the solder strip processing mechanism 20.

[0073] The solder strip processing mechanism 20 is used to stagger all the odd-numbered solder strips and all the even-numbered solder strips by a predetermined distance in a first horizontal direction, and alternately cut all the odd-numbered solder strips and all the even-numbered solder strips to obtain a plurality of first solder strip groups and a plurality of second solder strip groups.

[0074] The solder strip processing mechanism 20 is also used to adjust the spacing between each first solder strip group and the spacing between each second solder strip group to a first predetermined spacing.

[0075] The working process of the solder strip processing device of the present application is as follows:

[0076] The solder strip traction mechanism 10 tracts a plurality of solder strips extending along a first horizontal direction (such as the X-axis direction) to the solder strip processing mechanism 20.

[0077] The solder strip processing mechanism 20 implements processing of the solder strips, specifically including:

[0078] Firstly, the solder strip processing mechanism 20 staggers all the odd-numbered solder strips and all the even-numbered solder strips by a predetermined distance in the first horizontal direction.

[0079] Then, the solder strip processing mechanism 20 cuts off all the odd-numbered solder strips and all the even-numbered solder strips alternately, so as to obtain a plurality of first solder strip groups and a plurality of second solder strip groups.

[0080] Finally, the solder strip processing mechanism 20 adjusts the interval between each first solder strip group and the interval between each second solder strip group to a first predetermined interval respectively.

[0081] It can be seen that, through the cooperation of the solder strip traction mechanism 10 and the solder strip processing mechanism 20, the solder strip processing device of the present application completes the misalignment processing between the first solder strip group and the second solder strip group, and adjusts the interval between each first solder strip group and the interval between each second solder strip group to a predetermined value.

[0082] That is, the solder strip processing mechanism realizes simultaneous feeding of the first solder strip group and the second solder strip group, and completes the interval adjustment of the first solder strip group and the second solder strip group. In this way, the subsequent conveying mechanism can place all the first solder strip groups and the second solder strip groups on a plurality of battery pieces laid in advance at one time, thereby greatly improving the production efficiency of the battery string.

[0083] As shown in Figures 4 to 6 The solder strip processing mechanism 20 includes a plurality of first solder strip clamping assemblies 21, a plurality of second solder strip clamping assemblies 22, a plurality of first solder strip cutters 23 and a plurality of second solder strip cutters 24 arranged along a first horizontal direction, wherein:

[0084] The plurality of first solder strip clamping assemblies 21 clamp all the odd-numbered solder strips, and each adjacent first solder strip clamping assembly 21 is provided with a first solder strip cutter 23, each first solder strip cutter 23 is used to cut off all the odd-numbered solder strips at the corresponding position, so as to obtain a plurality of first solder strip groups.

[0085] The plurality of second solder strip clamping assemblies 22 clamp all the even-numbered solder strips, and each adjacent second solder strip clamping assembly 22 is provided with a second solder strip cutter 24, each second solder strip cutter 24 is used to cut off all the even-numbered solder strips at the corresponding position, so as to obtain a plurality of second solder strip groups.

[0086] Before all the odd-numbered solder strips are cut off, the plurality of first solder strip clamping assemblies 21 and the plurality of second solder strip clamping assemblies 22 are relatively translated in the first horizontal direction, so that all the odd-numbered solder strips and all the even-numbered solder strips are staggered by a predetermined distance in the first horizontal direction.

[0087] After all the odd-numbered solder strips are cut off, each first solder strip clamping assembly 21 clamps a corresponding first solder strip group thereon, and each first solder strip clamping assembly 21 is further configured to be separated in the first horizontal direction so as to adjust the spacing between each first solder strip group to a first predetermined spacing.

[0088] After all the even-numbered solder strips are cut off, each second solder strip clamping assembly 22 clamps a corresponding second solder strip group thereon, and each second solder strip clamping assembly 22 is further configured to be separated in the first horizontal direction so as to adjust the spacing between each second solder strip group to a first predetermined spacing.

[0089] In order to enable those skilled in the art to more clearly understand the structure and working principle of the solder strip processing mechanism 20, the working process of the solder strip processing mechanism 20 in the embodiment will be exemplarily described below.

[0090] As shown in Figure 6 one embodiment, the solder strip processing mechanism 20 includes six first solder strip clamping assemblies 21, six second solder strip clamping assemblies 22, five first solder strip cutters 23, and five second solder strip cutters 24, wherein: one first solder strip cutter 23 is arranged between each adjacent two first solder strip clamping assemblies 21, and one second solder strip cutter 24 is arranged between each adjacent two second solder strip clamping assemblies 22.

[0091] Figure 6 The working process of the solder strip processing mechanism 20 in the embodiment is as follows:

[0092] The solder strip pulling mechanism 10 is controlled to pull a plurality of (e.g., 17 in the figure) solder strips extending in the first horizontal direction (e.g., the X-axis direction in the figure) to the solder strip processing mechanism 20.

[0093] The first solder strip clamping assemblies 21 and the second solder strip clamping assemblies 22 are controlled to clamp the solder strips, wherein: the six first solder strip clamping assemblies 21 cooperate to clamp all the odd-numbered solder strips from different positions, and the six second solder strip clamping assemblies 22 cooperate to clamp all the even-numbered solder strips from different positions.

[0094] The six first solder strip clamping assemblies 21 are controlled to translate relative to the six second solder strip clamping assemblies 22, so that all the odd-numbered solder strips are staggered from all the even-numbered solder strips by a predetermined distance in the first horizontal direction.

[0095] Then, the five first solder strip cutters 23 and the five second solder strip cutters 24 are controlled to cut off all the odd-numbered solder strips and all the even-numbered solder strips from the corresponding positions synchronously. In this way, six first solder strip groups and six second solder strip groups are obtained. Each first solder strip group is clamped on a corresponding first solder strip clamping assembly 21, and each second solder strip group is clamped on a corresponding second solder strip clamping assembly 22.

[0096] Finally, the six first solder strip clamping assemblies 21 are controlled to translate and separate, thereby adjusting the spacing between the six first solder strip groups to a first predetermined spacing. The six second solder strip clamping assemblies 22 are controlled to translate and separate, thereby adjusting the spacing between the six second solder strip groups to the first predetermined spacing.

[0097] Continue to refer to Figure 4 As shown, optionally, the solder strip processing mechanism 20 further includes a base, and a staggered slide rail 25, a first solder strip group spacing slide rail 26, and a second solder strip group spacing slide rail 27 extending along a first horizontal direction, wherein:

[0098] The misaligned slide rail 25 is mounted on the base, the first strip group spacing slide rail 26 is slidably connected to the misaligned slide rail 25, and a number of first strip clamping assemblies 21 are connected to the first strip group spacing slide rail 26.

[0099] The second strip group spacing slide rail 27 is mounted on the base, and several second strip clamping assemblies 22 are connected to the second strip group spacing slide rail 27.

[0100] Before all the odd-numbered weld strips are cut, the first weld strip group is controlled to slide along the offset slide rail 25 on the offset slide rail 26, so that all the odd-numbered weld strips are offset from all the even-numbered weld strips in the first horizontal direction by a predetermined distance.

[0101] After all the odd-numbered solder strips are cut, several first solder strip clamping assemblies 21 are controlled to slide apart along the first solder strip group spacing slide rail 26, thereby adjusting the spacing between each first solder strip group to a first predetermined spacing. After all the even-numbered solder strips are cut, several second solder strip clamping assemblies 22 are controlled to slide apart along the second solder strip group spacing slide rail 27, thereby adjusting the spacing between each second solder strip group to a first predetermined spacing.

[0102] like Figure 7 As shown, optionally, the first solder strip clamping assembly 21 includes a first solder strip head clamp group 211 and a first solder strip tail clamp group 212. When the solder strip is pulled onto the solder strip processing mechanism 20, the first solder strip head clamp group 211 and the first solder strip tail clamp group 212 cooperate to clamp all the odd-numbered solder strips at corresponding positions. After all the odd-numbered solder strips are cut, the first solder strip head clamp group 211 clamps the head of the corresponding first solder strip group, and the first solder strip tail clamp group 212 clamps the tail of the corresponding first solder strip group.

[0103] The structure of the second solder strip clamping assembly 22 is the same as that of the first solder strip clamping assembly 21, which includes a second solder strip head chuck set and a second solder strip tail chuck set. When the solder strips are drawn onto the solder strip processing mechanism 20, the second solder strip head chuck set and the second solder strip tail chuck set clamp all the even-numbered solder strips at the corresponding positions. When all the even-numbered solder strips are cut off, the second solder strip head chuck set clamps the head of the corresponding second solder strip group, and the second solder strip tail chuck set clamps the tail of the corresponding second solder strip group.

[0104] Optionally, the first solder strip head chuck set 211 and the first solder strip tail chuck set 212 each include a plurality of first chucks arranged along a second horizontal direction (such as the Y-axis direction in FIG. 1) perpendicular to the first horizontal direction. After all the odd-numbered solder strips are cut off, each first chuck in the first solder strip head chuck set 211 clamps the head of a corresponding first solder strip, and each first chuck in the first solder strip tail chuck set 212 clamps the tail of a corresponding first solder strip. Figure 7

[0105] Similarly, the second solder strip head chuck set and the second solder strip tail chuck set each include a plurality of second chucks arranged along the second horizontal direction. After all the even-numbered solder strips are cut off, each second chuck in the second solder strip tail chuck set clamps the head of a corresponding second solder strip, and each second chuck in the second solder strip tail chuck set clamps the tail of a corresponding second solder strip.

[0106] Optionally, the first solder strip cutter 23 and the second solder strip cutter 24 have the same structure. Taking the first solder strip cutter 23 as an example, as shown in FIG. 2, the first solder strip cutter 23 includes a first mounting bracket 231, a fixed cutter 232, a movable cutter 233, and a movable cutter driving mechanism 234, wherein: Figure 8

[0107] The fixed cutter 232 is fixedly arranged on the first mounting bracket 231 and extends along the second horizontal direction. An upper side edge of the fixed cutter 232 is formed with a fixed cutting edge.

[0108] The movable cutter 233 is slidingly arranged on the first mounting bracket 231 and abuts against the fixed cutter 232. A plurality of hook cutters 235 are arranged side by side on the movable cutter 233 along the second horizontal direction. The hook cutters 235 extend upward beyond the upper side edge of the movable cutter 233, and a lower side edge of each hook cutter 235 is formed with a movable cutting edge.

[0109] ​​The movable cutter driving mechanism 234 is used to drive the movable cutter 233 to slide relative to the fixed cutter 232, so as to switch the position of the movable cutter 233 between the high position and the low position. When the movable cutter 233 slides to the high position, the movable cutting edges of each hook cutter 235 and the fixed cutting edges of the fixed cutter 232 form gaps for the welding ribbons to pass through. When the movable cutter 233 slides to the low position, the movable cutting edges of each hook cutter 235 and the fixed cutting edges of the fixed cutter 232 cooperate to cut off the welding ribbons passing therethrough.

[0110] Since the avoiding spaces are formed between the adjacent hook cutters 235, the first welding ribbon cutter 23 can avoid all the even-numbered welding ribbons which do not need to be cut when cutting off all the odd-numbered welding ribbons.

[0111] Similarly, the second welding ribbon cutter 24 can avoid all the odd-numbered welding ribbons which do not need to be cut when cutting off all the even-numbered welding ribbons.

[0112] As known by those skilled in the art, the number of the first welding ribbon groups and the second welding ribbon groups included in the back contact type battery string can be different, for example, as shown in Figure 2 When the battery string is welded by the even-numbered (4 in the figure) battery pieces, the number of the first welding ribbon groups (1st, 3rd and 5th welding ribbon groups in the figure) used is more than the number of the second welding ribbon groups (2nd and 4th welding ribbon groups in the figure) used.

[0113] In this case, the length of all the odd-numbered welding ribbons pulled out by the welding ribbon pulling mechanism 10 is longer than the length of all the even-numbered welding ribbons pulled out. That is, when pulling the welding ribbons, the welding ribbon pulling mechanism 10 needs to pull all the odd-numbered welding ribbons and all the even-numbered welding ribbons to different welding ribbon placing stations.

[0114] In order to be able to pull all the odd-numbered welding ribbons and all the even-numbered welding ribbons to different welding ribbon placing stations, the embodiment of the present application provides a new type of welding ribbon pulling mechanism 10, as shown in Figure 9 and Figure 10 The welding ribbon pulling mechanism 10 includes a first moving mechanism 11, a second mounting bracket 12, a fixed clamping plate 13, a first driving assembly 14, a second driving assembly 15, and a plurality of first clamping jaws 16 and a plurality of second clamping jaws 17 arranged staggered along the second horizontal direction. Wherein:

[0115] The second mounting bracket 12 is mounted on the movable part of the first moving mechanism 11, and the first moving mechanism 11 is used to drive the second mounting bracket 12 to move.

[0116] The fixed clamping plate 13 is fixedly connected to the mounting bracket 12.

[0117] The first driving assembly 14 is arranged on the mounting bracket 12, and the first clamping jaws 16 are configured to press all the odd-numbered solder strips against the fixed clamping plate 13 under the driving of the first driving assembly 14.

[0118] The second driving assembly 15 is arranged on the mounting bracket 12, and the second clamping jaws 17 are configured to press all the even-numbered solder strips against the fixed clamping plate 13 under the driving of the second driving assembly 15.

[0119] For the application scenario shown in the figure, that is, the length of all the odd-numbered solder strips pulled out is longer than the length of all the even-numbered solder strips pulled out, the working process of the solder strip pulling mechanism 10 is as follows: Figure 2 The first moving mechanism 11 drives the mounting bracket 12 to move to the initial pulling position of the solder strips (such as the solder strip cutting position), so that the pulling ends of all the odd-numbered solder strips and all the even-numbered solder strips extend onto the fixed clamping plate 13 and are located below the corresponding first clamping jaw 16 or second clamping jaw 17.

[0120] The first driving assembly 14 and the second driving assembly 15 drive the first clamping jaw 16 and the second clamping jaw 17 to rotate towards the fixed clamping plate 13, respectively, so that all the odd-numbered solder strips and all the even-numbered solder strips are pressed against the fixed clamping plate 13.

[0121] Then, the first moving mechanism 11 drives the mounting bracket 12 to move to the first solder strip placement position, and the second driving assembly 15 drives each second clamping jaw 17 to rotate away from the fixed clamping plate 13, so that the pulling ends of all the even-numbered solder strips are separated from the fixed clamping plate 13 and fall onto the first solder strip placement position.

[0122] The first moving mechanism 11 drives the control mounting bracket 12 to continue to move to the second solder strip placement position located behind the first solder strip placement position, and the first driving assembly 14 drives each first clamping jaw 16 to rotate away from the fixed clamping plate 13, so that the pulling ends of all the odd-numbered solder strips are separated from the fixed clamping plate 13 and fall onto the first solder strip placement position.

[0123] In this way, the length of all the odd-numbered solder strips pulled out by the solder strip pulling mechanism 10 can be ensured to be longer than the length of all the even-numbered solder strips pulled out.

[0124]

[0125] ​Of course, the solder strip pulling mechanism 10 can also control the first driving assembly 14 to perform the releasing action prior to the second driving assembly 15, so that the length of all the even-numbered solder strips pulled out is longer than the length of all the odd-numbered solder strips pulled out. Or control the first driving assembly 14 and the second driving assembly 15 to perform the releasing action at the same time, so that the length of all the even-numbered solder strips pulled out is the same as the length of all the odd-numbered solder strips pulled out, that is, all the even-numbered solder strips and all the odd-numbered solder strips are pulled to the same solder strip placement station.

[0126] In order to realize the avoidance of the solder strip pulling mechanism, optionally, the first solder strip clamping assembly or the second solder strip clamping assembly located at the front end is configured to be liftable.

[0127] When it is necessary to pull the solder strip to the solder strip processing mechanism, the first solder strip clamping assembly or the second solder strip clamping assembly located at the front end is first controlled to be lowered to a low position, so as to realize the avoidance of the solder strip pulling mechanism. After the pulling of the solder strip is completed, the first solder strip clamping assembly or the second solder strip clamping assembly located at the front end is controlled to be raised to reset.

[0128] Further, in an implementation manner, only the chuck clamping the head of the solder strip in the first solder strip clamping assembly at the front end or only the chuck clamping the head of the solder strip in the second solder strip clamping assembly at the front end is configured to be liftable. When it is necessary to pull the solder strip to the solder strip processing mechanism, the chuck clamping the head of the solder strip in the first solder strip clamping assembly at the front end is first controlled to be lowered to a low position, or the chuck clamping the head of the solder strip in the second solder strip clamping assembly at the front end is first controlled to be lowered to a low position; so as to realize the avoidance of the solder strip pulling mechanism. After the pulling of the solder strip is completed, the chuck clamping the head of the solder strip in the first solder strip clamping assembly at the front end or the chuck clamping the head of the solder strip in the second solder strip clamping assembly at the front end is controlled to be raised to reset.

[0129] Continuing to refer to Figure 1 As shown, optionally, the battery string welding equipment provided by the embodiment of the present application further comprises a solder strip unwinding mechanism and a solder strip cutting mechanism 30. The solder strip unwinding mechanism comprises a first mounting plate and a plurality of unwinding discs arranged on the first mounting plate. Each unwinding disc supports a roll of solder strip material and unwinds a solder strip. The solder strip unwound by the unwinding disc is guided into the solder strip cutting mechanism 30. The solder strip pulling mechanism 10 pulls the solder strip from the solder strip cutting mechanism 30 and pulls the solder strip to the solder strip processing mechanism 20.

[0130] When all the odd-numbered solder strips and all the even-numbered solder strips are pulled to the same solder strip placement position or different solder strip placement positions by the solder strip pulling mechanism 10, the solder strip cutting mechanism 30 cuts the solder strip.

[0131] Optionally, the battery string welding equipment provided in this embodiment of the invention further includes a tooling support frame 40 disposed above the welding strip processing mechanism 20 and configured to be liftable.

[0132] The tooling support frame 40 is used to receive and support several welding strip pressing tools with a second predetermined spacing. The welding strip pressing tools are aligned vertically with the first and second welding strip groups after separation on the welding strip processing mechanism 20 according to a predetermined rule.

[0133] When the welding strip traction device 10 and the welding strip processing structure 20 are performing welding strip traction and welding strip processing, the tooling support frame 40 is positioned at a high position away from the welding strip processing mechanism 20, thereby avoiding the welding strip traction device 10.

[0134] After the welding strip processing structure 20 completes the welding strip processing, the tooling support frame 40 carries several welding strip pressing tools supported on it and descends to a low position close to the welding strip processing mechanism 20.

[0135] Next, all the welding strip clamping fixtures, all the first welding strip groups and all the second welding strip groups are picked up from the tooling support frame 40 and the welding strip processing mechanism 10, and the picked-up welding strip clamping fixtures, first welding strip groups and second welding strip groups are laid on the pre-laid battery cells in one go.

[0136] In this way, only one handling and laying action is needed to simultaneously handle and stack multiple ribbon groups and multiple ribbon pressing fixtures onto the laid solar cells. After stacking, each ribbon pressing fixture presses the corresponding ribbon group onto the corresponding solar cell.

[0137] Optionally, the battery string welding equipment provided in this embodiment of the invention further includes a conveying mechanism.

[0140] Both the tooling suction part 62 and the welding strip clamping part 63 are mounted on the third mounting bracket 61.

[0141] When the third mounting bracket 61 is driven by the second moving mechanism to move to the pickup station above the tool carrying frame 40, the tool suction part 62 sucks a plurality of welding band pressing tools from the tool carrying frame 40, and the welding band clamping part 63 clamps a plurality of first welding band groups and a plurality of second welding band groups processed by the welding band processing mechanism 20.

[0142] When the third mounting bracket 61 is driven by the second moving mechanism to move to the laying station above the battery piece, the tool suction part 62 and the welding band clamping part 63 release a plurality of welding band pressing tools, a plurality of first welding band groups and a plurality of second welding band groups respectively, so that each welding band pressing tool, each first welding band group and each second welding band group are stacked on the corresponding battery piece.

[0146] The tool discharging carrying mechanism is used to carry the welding band pressing tools from the welded battery string back to the tool circulating conveying mechanism after the welding is completed.

[0147] Through the cooperation of the tool circulating conveying mechanism, the tool feeding carrying mechanism 50 and the tool discharging carrying mechanism, the present application realizes the circulation of the welding band pressing tools and the automatic feeding and discharging.

[0151] The plurality of tool suction plates 54 are slidingly connected side by side to the second mounting plate 52, and each tool suction plate 54 is used to suck one welding band pressing tool.

[0152] The mounting plate lifting mechanism 53 is used to drive the second mounting plate 52 to slide up and down along the fourth mounting support 51, so as to drive the various tool adsorption plates 54 to synchronously lift.

[0153] The interval driving mechanism 55 is used to drive the various tool adsorption plates 54 to slide to the middle or apart to adjust the interval between the various tool adsorption plates 54 to the second predetermined interval.

[0154] The working process of the tool loading and carrying mechanism 50 is as follows:

[0155] In the initial state, the various tool adsorption plates 54 are in the close state, and the second mounting plate 52 is in the initial high position.

[0156] The third moving mechanism drives the fourth mounting support 51 to move above the tool circulating conveying mechanism, and the mounting plate lifting mechanism 53 drives the second mounting plate 52 to descend to the low position, and the various tool adsorption plates 54 each adsorb a tool from the tool circulating conveying mechanism.
